3 Introduction
The new modular concept of the U1604 permits space-saving setup of an ECS Energy Control System in accordance with actual requirements. Thanks to strict software compatibility with the earlier U1601/2/3 summators and downward compatibility to the U1600 summator, previously used systems can be easily replaced or expanded.
An instrument can be set up using the following modules: · U1604 basic module with the following interfaces: · 1 ea. RS 232 (COM-1), 1 ea. RS 485 (COM-2), ECS LAN left + right, LON, 2 ea. S0
relay output · U1614 power pack module with status relay for supplying power to all components via
the TBUS and an additional 24 V DC output (max. 5 W) overall output power amounts to 20 W · U1624 S0IN12 input module with 12 S0-compatible inputs (up to 6 modules, max. 64 S0 inputs)
Connector Terminals All signals are fed to the instrument via screw terminals which can be unplugged (3, 4 or 5-pole). This assures trouble-free replacement in the event that servicing is required.

TBUS
The individual components are connected to each other via the so-called TBUS. The TBUS is laid out as a 5 conductor system and distributes 24 V DC supply power and signals from the TBUS communications interface (RS-485) to all components. The fifth conductor is used to indicate device status. One or two corresponding TBUS adapters are included with each U1604 component. These TBUS adapters (width: 17.5 or 22.5 mm) are snapped into the DIN top-hat rail in the fully assembled state before mounting the devices. Please note: The U1614 power pack module with an overall width of 35 mm requires two 17.5 mm TBUS adapters, and all other devices require one or two of the 22.5 mm TBUS adapters.

Cyclical Generation of all Channel Registers
Due to the fact that each channel has numerous energy data registers (33 registers without maximum values: Etot, EtotT1, EtotT2, Pmom, 10+1 times Eday, 12+1 times Emon, 4+1 times Eyear), only the most important summations are conducted continuously, and the less important ones in accordance with a rotating schedule. For example, Etot is ascertained continuously but Emon-12 only infrequently (roughly every 30 90 seconds). Power values other than Pmom are always calculated from energy values and thus don’t have to be totaled up.

Gossen Metrawatt GmbH

Channel Names A name can be assigned to each channel which can have a length of up to 8 characters. The channel can be better identified for data processing and display purposes with the help of this name. The name also makes it possible to access a specific channel per program system-wide.
<A> Etot Motor5
From summator A: a channel with the name “Motor5” is searched for system-wide and this channel’s total energy is displayed (see also ECL command: FINDER).
Virtual Channels · Each unused channel is available as a virtual channel, in order to generate any desired
sums or differences from physical inputs or other virtual channels. It doesn’t matter which summators the channels are assigned to within the ECS LAN system! · Unused physical channels can also be used as virtual channels, in which case even the maximum value registers of the corresponding physical channel are available. · The synchronizing-interval measurement data list can record data from virtual channels. Differential Coupling (ECL commands dVSUM and dVIRT) As of the moment of definition, incoming energy quanta (~ meter pulses) from the source channels are continuously summed up, and the summed up energy quanta are fed to the virtual channel as if they had actually just been measured. The virtual channel is thus decoupled from the source channels and data can be changed as desired. Application: logical coupling of the input signals (as if the corresponding input signals were connected to a single meter channel).
Example 1 Channel 26 at summator D: generates a cost center consisting of channels 1 5 + 8 of summator B: weighted at 0.7 and channel 4 of summator C: weighted at 0.3
H 1 = `B:DVSUM 1 .. 5+8 0.7, C:VSUM 4 0.3, D:VI
Example 2 Channel 10 is equal to the balance of channels 1 8 and the total sum of channel 9 (sum 1 8 minus channel 9)
H2=’dVSUM 1..8, dVSUM 9 -1, dVIRT 10=’
Numeric Range In order to achieve greatest possible accuracy, all internal calculation operations are conducted with 64-bit floating point numbers. As a result, 15 (!) significant decimal places are available.

Switching the Channel Display On/Off The on/off function only determines whether or not a channel is present at the display when scrolling through channel data or in a read-out with “*” (ECL command: ONOFF). Otherwise, the channel’s function is not influenced in any way.
Start/Stop Channel The acceptance of an input’s meter pulses is controlled with the start/stop function (ECL command: STARTSTOP). · A channel generated with “differential coupling” can be influenced by means of an ana-
log signal with the start/stop function. · Due to the fact that a channel’s binary input status is not influenced, this function can
be used, for example, to avoid undesired counting of binary information.
Energy Metering Meter pulses filtered in this way are integrated per channel in a temporary meter. Roughly once every 1 to 2 seconds, the meter values are converted to the corresponding energy values and the total energy registers are counted in as well. Pulses are converted to energy values in accordance with the following formula:
Energy Calculation

Energy kWh

where:

Uratio = U—U-s–e-p–cr–io-m–n–ad—ra-y–r-y-

Iratio = I–s-I-e-p–cr–io-m–n–ad—ra-y–r-y-

Electrical Power Billing
Instantaneous power is determined on the basis of the intervals between the incoming pulses. All other power values are calculated from the corresponding energy value in consideration of the respective time interval. By default, the calculation of power is based on an energy unit of measure per hour (kWh). In the case of other frames of reference (e.g. liters per minute,) the P factor must be correspondingly adjusted (ECL command: PFACTOR). The standard value is 3600, and for the liters per minute example it would be 60. Formula for calculating power from energy E and timespan dt: P = E * Pfactor / dt Only sensors which are connected via the LON network deliver already calculated power and energy values to the summators.

Six 4-pole connector terminals for two S0 inputs each. S0 input characteristics:
Input voltage = max. 30 V, input resistance = 5.1 k, bipolar, electrically isolated Due to the fact that the utilized optocouplers are bipolar, connection polarity is irrele-
vant.

Debounce Time and Counting Edge Debounce time and the counting edge (trigger edge) can be separately configured for each of the 12 inputs. Sampling time over all of the up to 12 channels amounts to 1 ms.
· Debounce time is adjustable from 0 ms to 20 s in 1 ms steps, ECL command: PULSE
· “+” (1) counting edge: Counting when change occurs from level 0 to level 1, ECL command: EDGE
· “-” (0) counting edge: Counting when change occurs from level 1 to level 0 If an input is used as a binary input, the selected debounce time applies to this operating mode as well. For example, if a debounce time of 1 s has been selected, only signals which remain stable at the “1” or “0” level for at least 1 second are further processed. The input status display at the control panel shows only the debounced signal levels.
4.4 S0 Outputs S1 … S2 The two freely programmable S0 outputs make it possible to transmit messages in the event that certain conditions occur. Switchable voltage is limited to 50 V in this respect. Furthermore, the outputs can also be used as floating pulse outputs for remote transmission of meter values with the help of ECL background programs (see ECL command S0REL 1 … 2).

4.5 Self-Test As long as the electronics are functional and no system errors have been detected, the status LED and the status relay are on. If an error has occurred at the device electronics, the relay drops out and the LED goes out. A horn, which can be controlled with the status relay’s NC contact, is then able to indicate the error status. The current relay status is displayed in the status window (section 6.8 on page 29). The function test can be expanded by means of appropriate programming (ECL command: STATCHECK, further information in the online help via ? STATCHECK). For example, the output can already be deactivated (error status) when available 24 V supply power drops to below 16 V, or when the status of the lithium battery no longer assures reliable data retention.
4.6 RS 232/485 Port Communication with the host PC, radio controlled clock, terminal, COM server, modem or printer is made possible by the RS 232 serial port.
Access to All Measurement Data A PC connected to the RS 232 port has full access to all of the system’s stored measured values. ECSwin parameters configuration software running at a PC manages all ECS data and permits tabular data evaluation.
Connection Configuration The RS 232 port is laid out with the DTE (data terminal equipment) configuration and the signals are available at a 9-pole D-sub plug connector. This DTE configuration corresponds to the same one that is commonly used for PCs and terminals. Refer to section 8 on page 55 concerning connector cable wiring.

4.7 Ethernet Port In addition to the COM-1 and COM-2 ports, ECL inputs via TCP/IP are available as well (see section 7.10 on page 49).

4.8 ECS LAN For applications which necessitate the use of more than 64 channels, several summators can be connected to each other via a multi-master-compatible RS 485 fieldbus (ECS LAN). Linking can be conducted by means of a 2-wire cable with bus or line structure. Maximum length per segment is 1200 m. Distances of several kilometers between 2 summators can be spanned with fiber-optic transmission lines based on 4-wire technology. Up to 255 summators can be connected to the ECS LAN. And thus a maximum distance of roughly 300 km can be spanned without an additional booster.
Multi-Master System Architecture The essential advantage of multi-master architecture results from the fact that each of the connected bus users has full access to the overall system’s data and functions. This means that it’s not necessary to select a single summator as the bus master.
General Information Concerning ECS LAN
· The connection technology for the individual LAN segments is freely selectable and can be mixed as desired.
· Transmission speed is dictated by the maximum cable length in accordance with RS 485. The ECS LAN normally runs at 62.5 kBaud, and the maximum cable length is thus 1.2 km (see also section 7.6 on page 43).
· The transmission cable must be terminated at both ends (but nowhere else) with terminating resistors. The terminating resistors are integrated and can be activated and deac-

Gossen Metrawatt GmbH

tivated via the control panel. Correct functioning of the 2-wire connection can only be assured with integrated terminating resistors. No external resistors may be connected! · Loop resistance of the transmission cable with 2-wire technology may not exceed 100 . · Up to 16 summators can be connected to a bus segment. If the terminating resistors are correctly connected (see above), branch lines have been minimized and the loop resistance of the transmission cable is less than 100 , up to 32 summators can be operated at a single segment. · User statistics can be retrieved via the control panel (device status).
Bus Left, Bus Right Each summator provides 2 complete ECS LAN ports. They’re designated LAN L and LAN R. Each of these ports can be operated with either 2-wire or 4-wire transmission technology (RS 485).
2-Wire A bus system within which several summators are connected to a common bus line must be set up with 2-wire technology.
4-Wire 4-wire technology is used where especially long transmission paths have to be spanned or where boosters are required, in which case only line-to-line connection is possible.
Connection Lengths (LAN bus) If several summators (up to 16) are arranged in relatively close proximity to each other (total bus length of max. 100 m), bus connection with a twisted pair cable is recommended. Line-to-line connection with a twisted four-wire cable should not be set up until the distance between 2 summators is greater than 400 m (max. 1200 m).

Assignment of ECS LAN Connections

User Directory Directory of ECS LAN Users Each summator automatically prepares an internal directory (ECL command: DIR) of all interconnected ECS LAN users (insofar as unequivocal IDs have been assigned throughout the entire system). Each summator indicates its presence system-wide every 3 seconds with a so-called broadcast message, so that all summators which receive this message can correspondingly update their internal directories. If the message is not transmitted for a period of more than 20 seconds, the respective summator is removed from the internal directories.
Unequivocal Identification An unequivocal summator ID must be assigned to each summator within the ECS LAN system. 255 different, freely selectable IDs are possible. An ID has the following format: A, A1 .. A9, B, B1 … B9, .. , Z, Z1 .. Z4
System-Wide Access to Measurement Data Example: You would like to retrieve total energy for channel 1 at summator D1 from summator A:
<A> D1:Etot 1

Gossen Metrawatt GmbH

4.9 LAN LED (LANL/LANR) Two LEDs, one for bus left and the other for bus right, indicate error-free operation of the ECS LAN:
· If no ECS LAN users are connected, the LEDs don’t light up.
· If one or more users are connected to the respective bus segment, the LED lights up.
· If two or more users have the same ID, the corresponding LAN LEDs blink at the users with the same ID. Exception: If the summators with the same ID are connected to the same LAN segment, no unequivocal error message is generated. For this reason, always compare the number of summators with the total shown in the user statistics when installing devices (control panel: device status).
· If the internal terminating resistor is not activated during bus operation, the affected LAN LED blinks.

4.10 LON Connection
LON is an intelligent bus concept which makes it possible for controllers, sensors and actuators to “talk” to each other. Quick and inexpensive wiring is achieved by means of intelligent decentralization. All of the nodes (users) are equipped with a neuron chip and communicate with each other via the LON Talk protocol. Data is transmitted via a standardized, floating, twisted pair cable which can be wired in bus, ring or star topology as desired (free topology!). The electrically isolating FTT10 transceiver used to this end is reverse polarity protected and transmits data at 78 kbps. Up to 63 nodes can thus be additionally connected to a U1604 summator via the integrated LON network. Energy values from the LON meters can be freely assigned to channels K1 to K64 via differential coupling.

5.2 Synchronizing Interval Measurement Data List The energy values measured during a specific interval can be saved to a measurement data list. This interval (duration: 10 s … 999 hrs., default: 15 minutes) is either derived from system time or the interval limit is determined by the edge of the meter pulse (default: channel 11). Energy measured during the interval (EINT) is entered to the list along with date and time. The mean power value for the interval (PINT) is calculated from EINT and the duration of the corresponding interval.
Formatting the Measurement Data List

Attention!

The contents of the measurement data list are deleted during formatting.

The number of entries in the measurement data list depends on the number of channels. The measurement data list can thus be formatted according to the desired number of channels. Formatting is only possible via an interpreter. The resolution of the data range is determined at the same time (ECL command: FORMAT).
Specifying the Number of Entries The format command reserves space within system memory for the selected channels. In this way, the possible number of entries (records) is specified, but not the recording duration which depends entirely on interval time. Example: Only channels 1 through 4, channel 17 and channels 21 through 23 will be recorded to the measurement data list.

<A>FORMAT = 1..4+17+21..23
If the format command is invoked without parameters, status information is read out to the measurement data list. In particular how many entries can be recorded in the measurement data list is shown here.
<A> FORMAT = 1…4 + 17 + 21 …23 <A> format Format (0): 8 channels, 26,214 entries (= 273 days with an interval of 15 minutes) Channels: 1;2;3;4;17;21;22;23
Reading Out the Measurement Data List The data saved to the measurement data list can be read out together with date and time via the serial port by means of ECL command EINT. The following example shows the read-out of all measurement data from channels 1 through 5 in ASCII database format:
<A> Eint/## 1..5 * ** 16.04.93;17:45:00;1;0.5;0.75;0.99;1.36 16.04.93;18:00:00;1.01;0.1;0.76;0.80;0.83 16.04.93;18:15:00;0.99;0.48;0.75;1.02;1.28

…

Gossen Metrawatt GmbH

Retrieving a Specific Entry The ECL command INDEX makes it possible to read out data as of a specific date. The following example (in plain text read-out) shows the value from the measurement data list for channel 1 on 16 April 1993 at 6:15 p.m.:
<A> Index 16.04.93 18h15, Eint/ 1 . 16.04.93 18:15:00 : Eint-863 (01:Motor7) = 0.99 kWh
Memory Structure of the Measurement Data List The measurement data list is a ring buffer of fixed size which is correspondingly formatted. It’s accessed by means of an index number. Index 0 always makes reference to the most up-to-date, current interval. Index 1 makes reference to the last interval and index 2 to the next to last etc. The ECL command INDEX converts a timestamp into the corresponding index number.
Ring Buffer When memory capacity has been exhausted, the oldest entry (with the highest index number) is deleted in favor of the new entry. Index 1 is thus assigned to the interval which has just been concluded, and the index numbers of all previous entries are increased by 1.
Measurement Data List Value Range Limitation of Resolution due to Data Reduction All of the summator’s data registers have an internal width of 8 bytes (64-bit floating point). However, this has to be converted to a data format with a width of 2 bytes for the data list (as of Eint-1), for which overall recording duration is directly dependent on available memory capacity (which is associated with reduced accuracy). The fact that only energy values are saved (and not power values because these are calculated) results in the following limitation of the numeric range with standard “0” formatting:
Data range encoding: (0: standard. Resolution specified in [ ]) 0 : 0…+/-0.8191[0.0001]…+/-81.91[0.01]…+/-8191[1]…+/-819100[100] 1 : 0…+/-8,191[0.001]…+/-81.91[0.01]…+/-819.1[0.1]…+/-8191[1] 2 : 0…+/-16383[1]……+/-163830[10] 3 : 0……+32767[1]………+327670[10] 4 : 0..+/-99999999 [8 decimal places, smallest place: 1E-6] If the number is > 99999999, the leading places are omitted. 1234567890 –> 34567890 Omission of the first 2 places 12345678.9 –> 12345679 8. Place is 5/4 rounded 1234567.8 –> 1234567.8 No limitation 12.345678 –> 12.345678 No limitation 12.3456789 –> 12.345679 8. Place is 5/4 rounded 1.23456789 –> 1.234568 Only 6 places after the decimal (see below)
Notes Encoding types 0, 1, 2 and 3 use two bytes per entry, but encoding type 4 uses four
bytes per entry and memory duration is thus cut in half. Encoding type 4 is only available as of V2.46, and interval data with type 4 encoding
cannot be read out from summators with older firmware versions! With encoding type 4 the smallest resolution is 1E-7, and with faster read-out using
ext.’#’ resolution is 1E-6 (the 6th place after the decimal is 5/4 rounded if required).

6 Operation (display menus)
The U1604 summator is not equipped with any display or control elements. ECSwin software is used for communication and parameters configuration. The display in the panel mode corresponds to menu prompting for a U1601 summator. Extreme care is required when changing the parameters of serial ports COM1 and COM2. In the case of different settings no communication is possible between the PC and the summator. Only one interface should be changed at any given time so that the summator can still be controlled with the other. COM2 is set to ECL or ECL+HP to this end.

Date/Time After entering the time to the first line, the cursor jumps to the date line. Entries are immediately active at the integrated real-time clock for which reason the entry cannot be aborted. ECL command: TIME/DATE
Summator Name The summator name must have a length of 1 to 8 characters. If no name is entered, “-” is automatically assigned as the name. The following characters are possible: _+ 0 … 9 A … Z a … z . ECL command: SUMMATOR
Summator ID Unequivocal IDs must be assigned within an ECS LAN. The same ID may never be assigned twice. Up to 255 IDs are possible. The character string has a maximum length of 2 characters. If a blank space is entered as part of the character string, the character string is cut off as of the blank space after the entry has been acknowledged (F4). An ID has the following format: A, A1 … A9, B, B1 … B9 … Z, Z1 … Z4.
Interval Time Entry range for the synchronizing interval: 10 seconds to 999 hours (entry in seconds). ECL command: INTERVALL (ITV)
Interval Source The synchronizing interval can be generated in three different ways: Time: the intervals are generated in accordance with the selected interval duration. Program: An interval is only generated with the ECL command SYNC=. Channel 11: A meter input serves as a binary input for the synchronization signal. The selected pulse duration and edge are taken into consideration. ECL command: INTERVALSOURCE (IS)
Source (tariff source) The valid tariff, T1 or T2, can be selected in two different ways: Channel 12: A meter input serves as a binary input for specifying the valid tariff. The selected pulse duration is taken into consideration. The edge parameter is used to specify which level is assigned to tariffs T1 and T2. If the “+” (1) edge is selected, logical zero (0 V at the input) corresponds to tariff T1, and logical one (24 V) to tariff T2. The opposite applies when the “-” (0) edge is selected. Program: The valid tariff is specified with ECL command TARIFF=1 or TARIFF=2. These assignments only work if “Program” is selected as the source. ECL command: TARIFFSOURCE (TS)
Tariff Unit The character string has a maximum length of 4 characters. The tariff unit must have a length of at least one character. ECL command: TUNIT
T Fixed Point Specifies the number of places after the decimal which will be used for displaying accrued energy costs. ECL command: TFIX
Cost Factors T1 and T2 The procedure for entering the cost factors for tariffs T1 and T2 is the same. The cost factor is used to convert energy to costs. This conversion can be used for the tariffs’ total energy registers: ETotT1, ETotT2 and ETotT1T2. Entry ranges for cost factors: 0.000 to 99.999 ECL command: COSTFAC1 COSTFAC2

LCD Contrast This menu is used to set contrast at the LCD. 20 steps are possible (-5 … +15). The default value is 0 which provides good results in most cases.
Language All menus, ECL messages and online help texts are displayed in the selected dialog language. ECL command: LANGUAGE
Date Format Three display formats are possible: dd.mm.yy, mm/dd/yy, mm-dd-yy.
S0 Mode Selection of the operating mode of S0 outputs S1 … S2. In the PROG position, a user program (H/P program) determines the status of the outputs. ECL command: RELM.
S0/Level The sensitivity of the S0 input channels (S1 … S2) can be specified in steps (10, 25, 50, 70%). ECL command: LEVEL

4: LON:

The channel is shut down entirely and all functions are off. The U1604 is not equipped with an analog module. PMOM=ANA ENERGY (see section 6.2) A binary input quantity in accordance with the S0 standard is used for energy measurement (COUN) (see section 6.2). Energy measurement data are fed to the system via interconnection of various LON users.

5: LON ANA Analog values via LON for A2000, A210/A230, DME400, U1661, U168X, U128X W1, U138X W1, U228x W1 and U238x W1 (see section 6.5)

7: LON-INP binary inputs via LON for U1660 8: LON-REL relay outputs via LON for OCL210
Channel Names A name can be assigned to each physical channel for improved identification. The name doesn’t have to be unique, unless it will be used as a field name in a database. The character string has a maximum length of 8 characters, and has to be at least one character long. ECL command: CHANNEL
Long Name An extended channel name with up to 20 characters. ECL command: LNAME
E Unit, P Unit A freely definable energy unit (e.g. kWh) and a power unit (e.g. kW) can be assigned to each physical channel. The character string has a maximum length of 4 characters, and has to be at least one character long. ECL command: EEINH, PEINH

(Channel) Visible For each physical channel it can be specified whether or not it will be visible in the case of queries executed at the control panel or in “*” lists in the interpreter mode. This has no effect on the functioning of the channel! For example if only channels 1 to 3 are activated, you can only retrieve values from these 3 channels in the normal display the device appears to have become a 3-channel unit. Even “Etot*”, when queried in the interpreter mode, displays total energy from these three channels only. If all channels are shut down, date and time appear in the normal display. Entries become effective immediately and don’t have to be acknowledged. ECL command: ONOFF
Start/Stop Channel
The acceptance of an input’s meter pulses is controlled with the start/stop function. A channel generated with “differential coupling” can be influenced by means of an analog signal with the start/stop function. Due to the fact that a channel’s binary input status is not influenced, this function can be used, for example, to avoid undesired counting of binary information. Entries become effective immediately and don’t have to be acknowledged. ECL command: STARTSTOP (STSP)

Gossen Metrawatt GmbH

Fixed Point For each physical channel it can be specified with how many places after the decimal point energy or power values should be displayed (not calculated). (0) no places after the decimal point0(2) two places after the decimal point0.00 (1) one place after the decimal point0.0(3) three places after the decimal point0.000 Entries become effective immediately and don’t have to be acknowledged. ECL command: CFIX
C Factor This makes the following possible, for example: The measured quantity is consumption in cubic meters. This should be displayed as standard cubic meters [Nm3] which makes a correction factor necessary. The C factor is thus a multiplication factor for calculating the energy value of a channel.
Meter Constant The meter constant can be separately defined for each of the physical channels. It indicates how many meter pulses a connected meter delivers per kWh and is used in the energy calculation formula (see page 11). ECL command: MCONST
U Ratio, I Ratio The factors for U ratio and I ratio can be separately defined for each of the physical channels. Calculation formula: see page 11. Change plus or minus sign: Press “<<” (F2) when the cursor is all the way to the left. Entry range for U ratio and I ratio: 0.000 to 99,999.999 A channel can be disabled for meter pulses by setting the Urat or Irat factor to zero. However, it’s better to use the start/stop function. ECL command: URAT, IRAT
Note Detailed descriptions of URAT and IRAT are included in the commands list (3348-870-01).
P Factor The P factor can be separately defined for each of the physical channels. Calculation formula: see page 11. Change plus or minus sign: Press “<<” (F2) when the cursor is all the way to the left. Entry range for the P factor: 0.001 to 99,999.999. ECL command: PFACTOR
Pulse Duration The duration for which a pulse must be applied to a channel’s S0 input in order to be recognized as an S0 pulse (debounce time). ECL command: PULSE
Edge Specifies whether the meter pulse will be triggered at its positive (1) or negative (0) edge. ECL command: EDGE

LON Channel LON user U2289 with the selected neuron ID has 36 channels. Of these, channel 40 (active energy import) is represented at local channel 1, when channel 1 is set to the LON mode.
LON Activity The LON user can be shown (run) or hidden (stopped) with this function, without having to shut down individual channels.
Neuron ID This is the globally unique address of a LON user and consists of a 12-place hexadecimal value. The summator automatically establishes contact with the LON user to which this address is assigned. If the local channel is set to the LON mode, the remote “LON CHANNEL” (channel 40 in the above example) is represented.

LON Factor, LON Offset
The values of LON users are standardized to a value of -1 … 0 … +1. The characteristic range curve can be adapted as desired to the measuring task with the help of the LON factor and LON offset parameters. ECL commands: LONFACTOR, LONOFFSET.

ECS LAN via COM
If a 4-wire ECS LAN connection has to be set up by means of an asynchronous V24 interface, a new mode is available for the serial ports as of V2.48:

LAN-R or LAN-L.

Example: Two devices need to be linked by means of a TCP/IP network at the ECS LAN level. Two COM servers are used to this end, each of which is connected to one device via RS 232 port and networked via Ethernet. COM servers forward characters transparently from the RS 232 port to the assigned COM server. As soon as LAN-R or LAN-L is selected in the setup menu from COM-1 or COM-2, the ECS LAN data stream is redirected to this COM port. The interface parameters used by the COM port including baud rate, parity and handshake are then decisive, and not the previous ECS LAN settings any more. Recommendation: highest baud rate (115,200), parity off, handshake RTS/CTS. The selected settings must coincide with the settings of the interconnected COM server, but they can differ from those of the partner if necessary. Please note that the currently unused ECS LAN may/should no longer be utilized. It must also be assured that the terminating resistor is activated for 2-wire parameters configuration, so that no ESC LAN errors can occur.

Gossen Metrawatt GmbH

Special Case: Use of COM and ECS LAN Connection
The ECS LAN connection is shut down in the “ECS LAN via COM” mode. Outgoing frames are transmitted via the corresponding COM port, as well as via the ECS LAN port. Incoming frames from both ports are processed. Nevertheless, this is not a star hub configuration, because the two ports (COM and ECS LAN) don’t “see” each other.

A 2-wire cable is normally used (terminals 45 and 46 or 49 and 50) only in this way is bus configuration possible with several users on the same bus line. However, the integrated terminating resistors in the first and the last device on the bus line have to be activated to this end. Correct functioning of the bus is not possible without terminating resistors (bus LEDs LAN/L and LAN/R blink). For long transmission paths or where boosters are required, 4-wire transmission technology can also be used (only line-to-line connection is possible in this case). The required terminating resistors are activated automatically. The standard baud rate is 62.5 kBaud.

Additional instructions on configuring the port (parameters of the SET… type) can also be found in the commands list (3-348-870-03).

7.8 Firmware Update Installing new firmware is only possible via the RS 232 COM-1 port.
ECSUpdate.exe software with correctly configured INI file (ECSupdate.ini) is required on the PC. The previous program for the U1601/2/3 (Update32.exe) cannot be used. However, the new program supports old U1601/2/3 summators.
In order for the ECSupdate.exe PC program to be able to install the firmware, the bootstrap loader mode has to be activated at the U1604. Proceed as follows to this end:

· Press and hold the SET key for 5 seconds, or hold it depressed while switching power on.
· LED 1 (the top LED) lights up (with brief inverting once per second) 115,200 baud.
· Other baud rates can be selected by repeatedly pressing the SET key. After pressing the key several times, selection starts over again at 115,200 baud (LED 1 lights up):

115,200 1

230,400 1 2

460,800 1 2 3

921,600 1 2 3 4

9,600 4

19,200 3

38,400 2

The correct firmware version is then selected with the PC program and the configuration of the COM port and the associated components is checked. Firmware uploading is started after acknowledging with OK. The LEDs light up continuously during booting, and after several seconds (depending on the baud rate) they’re interrupted repeatedly for roughly 1 to 2 seconds. After booting has been completed, the PC program automatically executes a reset and thus restarts the device. If any problems should occur, this reset can also be forced at the device: Reset: Press and hold the SET key until all LEDs go out or power off/on.
Caution: Partially uploaded firmware is not functional and must be fully uploaded without delay. Nevertheless, the bootstrap loader can generally be started even if the firmware is not functional.

Time required for booting depends on the selected baud rate (approximate values: roughly 3 minutes at 115 kBaud and roughly 35 seconds at 921 kBaud).
Recommendation for selection of the ideal baud rate for the COM-1 port:
· If the PC is equipped with an integrated RS 232 port, the drivers (hardware) are usually not capable of using baud rates of 230 kBaud use 115,200 baud.
· If the USB RS 232 converter cable (with FTDI chip directly in the USB plug) is used, the fastest available baud rate of 921,600 baud can (usually) be used without any trouble.

Gossen Metrawatt GmbH

Using the Z302V Programming Cable The cable requires corresponding Windows drivers which, depending on the Windows version, are installed automatically the first time it’s connected to the PC. In most cases the driver is installed automatically as of Windows 7, and in Windows 10 the driver is already on board.
If the driver has been installed correctly, the user only has to specify the desired COM port. The system automatically assigns a COM port number, which can or must be changed accordingly in the Device Manager. This procedure is described in section 5 of the condensed operating instructions (“COM Settings”) as well as in the following section. Here’s an excerpt:
Device Manager Connections (COM & LPT) — USB Serial Port (COM1) —- Properties of the USB Serial Port (COM1) —— Connection Settings Advanced … ——– Advanced Settings for COM1 ———- Select COM1, COM2, COM3 …
Please refer to the following web pages for more information on the drivers:
http://www.ftdichip.com/Drivers/VCP.htm
The easiest way to install the driver (32 and 64 bit) if it’s not installed automatically is to use the setup executable available at the following address:

Attention!

Changes to the setting may render the device unusable, insofar as the faulty

settings cannot be corrected via another correctly functioning interface.

Recommendation for selection of the ideal baud rate for the RS 232 COM-1 port: · If the PC is equipped with an integrated RS 232 port, the drivers (hardware) are usually
not capable of using baud rates of 230 kBaud use 115,200 baud. · If the USB RS 232 converter cable (with FTDI chip directly in the USB plug) is used,
the fastest available baud rate of 921,600 baud can (usually) be used without any trouble.
Recommendation for selection of the ideal baud rate for the RS 485 COM-2 port: · This RS 485 port works in the half-duplex mode no handshake is possible for which
reason this function is always deactivated. And thus under certain circumstances, the baud rate must be selected such that no buffer overflow can occur (usually no problem with ECL protocol). · With an FTDI chip-based USB RS 485 converter, the fastest available baud rate of 921,600 baud can be used without any trouble.
Tip: The COM port for FTDI-based USB RS 485 converters can be permanently assigned in the device manager, and management of two or more virtual COM ports can thus be optimized:
Device Manager Connections (COM & LPT) — USB Serial Port (COM1) —- Properties of the USB Serial Port (COM1) —— Connection Settings Advanced … ——– Advanced Settings for COM1 ———- Select COM1, COM2, COM3 …

Relays 3 through 6 have been prepared values can be assigned and settings can be selected, but they don’t have any effect.

S0 Pulse Output Pulse sequences can be read out with the S0 relays which generate equivalent S0-compatible pulses in accordance with the change to the energy value of a given channel (1 … 64). Associated commands:
S0PCH <rel> = <source_channel> (specifies the target relay and the source channel) S0PDELTA <rel> = <energy_per_pulse> (indicates the energy quantum for which 1 pulse
is generated) S0PMS <rel> = <pulse_duration_ms> (duration of one pulse in ms)

Mapping the Status of the U1604 to Relay 1 or Relay 2
When the U1604 basic module is used without the U1614 power pack module and external 24 V auxiliary power is fed directly via the TBUS, no status relay is available. In order to make a status output available for this configuration, the status of the U1604 can be mapped to relay 1 or 2.

8.4 TBUS Connection The 5-pole TBUS is used to connected all SU1604 modules to each other. This connection is implemented by means of TBUS connectors which are included with each device and are snapped into the top-hat rail after plugging them together. The individual components are then latched onto the top-hat rail at the corresponding position. This procedure connects the devices to each other no wiring is required.
In certain applications it may be necessary to:
Use a special power pack instead of the U1614 power pack module
Connect the TBUS from one top-hat rail to another
Operate two or more U1604 basic modules with one U1614 power pack module

Attention!

During operation when auxiliary power is active, neither the U1604 basic module

nor any other S0 modules may be mounted to or removed from the TBUS.

In these cases connection to the TBUS is accomplished with special 5-pole terminals (3.81 mm grid), which differ for right (PS 1719697) and left (PC 1719707) connection.

The individual TBUS components are automatically connected to earth potential on the top-hat rail via a contact in the housing.
TBUS GND does not have a low-impedance connection to PE, except for interference suppression with 1 nF/1 kV capacitors and protection against excessively high potential differences with a 275 V varistor in the U1614 power pack module between GND and PE.

9 Programming
9.1 General Information
ECL Energy Control Language The flexibility of the ECS is based on the programmability of the individual summators using the ECL programming language (energy control language), which was specially developed for the ECS. Refer to the operating instructions for the ECL interpreter and the commands list for further information concerning this high-level language which is similar to FORTH but, like BASIC, is easy to learn. Thanks to this programmability, the following additional system characteristics are made available:
Virtual Channels Even complex formulas for the creation of virtual channels can be clearly and concisely formulated as background programs. There’s no predetermined schema which inhibits flexibility.
Programming the Relays Relay switching can depend on numerous conditions. With ECL, any desired conditions can be formulated, even cross-summator conditions. The conditions are evaluated continuously as a background program. Simple energy management, for example, can involve a special type of relay output programming.
Simple Energy Management Example: If a consumer’s mean power exceeds a given value, the consumer is shut down by switching one of the 2 relays. Whether or not this shutdown is at all desirable can be ascertained by checking system time (e.g. only at night), by polling a binary input (e.g. only switch when logical one is applied to input 10) or by evaluating the power values of other consumers.
Tariff Changeovers Time comparison functions in background programs make it possible to respond to special requirements for tariff changeovers.
Flexible Adaptation to Database-Specific Transmission Formats Continuously recurring queries of datasets can be saved as a normal P program. Entirely ASCII-oriented database formats can be compiled in a program of this sort. Data transmission is started in accordance with the desired format after invoking this program.
Background Programs H0 … H31 32 background programs are available, namely H0 … H31. Each program can take on up to 127 characters. The background programs are executed in the background, one after the other. Thanks to the operating system’s multitasking structure, the background programs have absolutely no effect on the normal operating sequence.
Programs P0 … P31 and Q0 … Q31 64 programs, namely P0 … P31 and Q0 … Q31, receive continuously recurring command inputs which can then be processed by simply invoking the corresponding program. Nesting of programs is possible, and a normal P program can be executed as a subprogram from a background program.

Gossen Metrawatt GmbH

Program Names Names can be assigned to P programs. P programs can be addressed system-wide with their names.
9.2 Parameters Configuration and Data Visualization at a PC The easiest way to communicate with a summator from a PC is via terminal emulation, e.g. with the help of HyperTerminal. However, adequate knowledge of the commands is absolutely essential.
ECSwin provides a much more convenient method:
Program features: ECSwin is used primarily for configuring parameters at U1600, U1601, U1602, U1603, U1604 and U1615 summators in an ECS LAN. Beyond this, reading in and visualizing energy consumption data in the form of measured value tables and graphics (online displays) is supported as well. The 32-bit program (as of V3.4.x) runs under MS Windows Vista and 7 (32 and 64-bit), as well as 8 and 10. Connection to the U16xx is possible via TCP/IP or RS 232.
The following functions are provided by the software: · A dialog box for logging on and configuring access authority · A dialog box for setting time in the ECS LAN · A dialog box for configuring summator parameters · A dialog box for configuring channel parameters · A dialog box for setting meter readings · A dialog box for configuring relay parameters · Transfer user created commands to the summator · A dialog box for generating virtual channels · Control panel display (including device display, keys and LEDs) for U1600, U1601 and
U1604 · Ascertainment and graphic representation of ECS LAN network topology · Querying and display (as table or characteristic curve) of intervallic, daily, monthly and
annual energy and power data which have been stored to memory at the summator. · Querying and graphic display of currently measured values in data logger format · Data transmission via modem (maintenance of a dial-up list) · Terminal emulation

Gossen Metrawatt GmbH

9.3 ECL Extensions and Notes on Compatibility
This section includes extensions to the ECL interpreter language as well as notes concerning compatibility.
Addressing Up to 255 Devices in the ECS LAN System
ECL permits direct addressing of up to 255 devices in the ECS LAN system by placing the device ID (A:,A1:…A9:,B:,B1…B9:,…,Z:,Z1:…Z4:) in front of the command. Example for querying the firmware version of devices A1: and C7: A1 : VER, C7 : VER The so-called “local” device, which is connected to the PC directly via the RS 232 or TCP/IP port, can be directly addressed with special ID AA:, without having to know the exact ID. The default context is normally set to the local device, so that use of special ID AA: is only necessary in exceptional cases. This is usually made apparent in the terminal programs by means of a prompt at the beginning of the line in the form of “<A>” for device A:.

Examples (do not enter prompt <A> it’s generated by the terminal program):

<A> VER <A> ALL, VER <A> C1: VER, EGES 1

read out version information from device A: read out version information from all available devices VER read-out from device C1: and read-out of ETOT 1 from device A:

(change of device context one-time only for C1:)
<A> C1: , VER, EGES 1 VER read-out and read-out of ETOT 1 from device C1:

(C1: becomes line context valid through the end of the line)
<A> C1: , VER, AA : ETOT 1 VER read-out from device C1: and ETOT 1 from device A:

(although C1. becomes line context, special ID AA: applies to ETOT A:)

Differentiation Amongst Local and Remote Devices In the case of varying firmware and/or device types within the ECS LAN system, it’s important to differentiate amongst “local” and so-called “remote” devices and summators. Which devices are responsible for the transmission of data between these via the ECSLAN is usually irrelevant, although of course data throughput can differ significantly depending on device type. The ECL command interpreter always runs at the local summator, and must therefore be capable of understanding all of the commands used in the command line. If it doesn’t know one of the commands, this results in a SYNTAX ERROR.
· For example in a system comprised of U1600, U1601/2/2/3 and U1604 summators, all of the commands of a “remote” U1600 summator can be processed by a U1604 summator which functions as the “local” summator (downward compatibility).
· But this doesn’t work the other way around when the U1600 is the “local” summator and the U1604 is the “remote” summator. All of the commands from the U1604 summator which are unknown to the U1600 summator result in errors. Nevertheless, all of the commands known to the U1600 can be executed on/with a remote U1604 (limited upward compatibility).

Note: There are also command groups such as SYS, LON, REC etc. which fundamentally have to be known by the local summator, although the exact command (e.g. SYSIP) is first interpreted by the remote summator.

The terms local device and remote device have been explained here in detail because they have to be used again and again in the following sections in order to illustrate complicated internal relationships.

9.4 INDEX Command Bug for U1601/2/3 with Use of UTC The INDEX command is used for a time search in order to find a certain entry in the interval measurement data list. The bug in U1601/2/3 firmware as of V2.48 described below was detected and eliminated in June 2017.
Insofar as all summators within the ECS LAN system work exclusively with local time (in which case the following applies: UTCTZ = 0 and UTCDST = 0), the INDEX command functions flawlessly.
But as soon as UTC time is used system-wide (for example Germany: UTCTZ = 1, UTCDST = 1), the INDEX command doesn’t find the right entry if a local time is searched for with the time search and the addressed summator is a U1601/2/3 with firmware (FW) older than June 2017. In this case, the result of INDEX <time specification> erroneously corresponds precisely to the results of INDEX° <time specification>.
If a UTC is searched for (with the “°” extension), the entire system functions flawlessly. This also applies to U1600 summators, which have to be set to local time for systemwide UTC time processing because they don’t offer any internal UTC time processing.

Notes
System time UTC means that all real-time clocks (RTCs) are set to UTC time and all (local) time specifications are converted in accordance with the time zone (UTCTZ) and the daylight savings time setting (UTCDST). Internal timestamps are always in UTC and are thus strictly monotonic increasing, regardless of any changeovers between daylight savings and standard time.
The workaround for the above mentioned error can be used insofar as the “local” summator is a U1601/2/3 as of firmware V2.48 or a U1604: date//- <tt.mm.jj_local> <hh:mm:ss_local>,loc2utc .,INDEX° .,eint// <kan> . <number> Local search time is thus converted to UTC and this UTC time is transferred to the INDEX° command via stack reference “.”. The above table makes it apparent that the INDEX° command with UTC time search works in a trouble-free fashion. If the firmware of the U1601/2/3 summator is older than V2.48, no UTC processing is possible. In this case it’s only possible to proceed as with U1600 summators and to set local time to UTC time.

9 The search must be conducted by a “remote” device (U1601/2/3, U1604) not by a U1600 device because this has to run with local time = UTC time.
10 This also applies when UTC time processing is not active, but all summators within the ECS LAN are nevertheless running on UTC time instead of local time (meaning: continuously monotonic increasing time). The search time specification must then be specified in displaced local time the “°” extension doesn’t play any role at all.

11 LON Bus System Structure
The most commonly used transmission medium for industrial and building management applications is twisted pair copper cable, which is used together with the electrically isolated FTT-10A transceiver. Both of the conductors can be connected to either pole, and installation is thus reverse polarity protected. Maximum transmission distances are influenced by the electrical characteristics of the cable, and the network topology. Utilized cables should comply with the stipulated specifications in order to prevent interference during communication. Due to the possibility of reflections, only one cable type may be used in any given bus segment.
Network Topologies

Bus Topology (bus terminator at both ends)

Free Topology (bus terminator at one end)

If a bus structure is used, the components are connected in parallel, one after the other. A bus terminating resistor must be used at each end. Branch lines may not exceed a length of 3 meters. Only one bus terminator is required with free topologies, but transmission distances are limited in this case.
If repeaters are used, the bus signal can be boosted thus increasing maximum possible transmission distance. Due to response characteristics, only one passive repeater may be included in any given bus segment. The transition to other physical transmission media, and/or targeted forwarding of data packets to individual bus segments, is accomplished by means of routers. The following recommendation is based upon experience gained by Gossen Metrawatt GmbH during installation and start-up of LON systems. The environment within which the cable is laid has a decisive influence on correct cable selection, and must therefore be taken into consideration during the planning stage. All generally applicable directives for laying control and telecommunications cables must be adhered to during installation.

11.2 Cable Type
Inexpensive wiring is possible for applications in environments with minimal interference using the following cable type: JY (ST) Y 2 ea. 2 × 0.8 mm with twisted wire pairs. The above specified dimension of 0.8 mm refers to the diameter of the wire, which results in a wire cross-section of 0.5 square mm. In most cases no shielding is required. It may be possible to eliminate communications problems occurring in environments with excessive interference by connecting the shield at one end. If cables are used which contain several wire pairs, it may be advantageous if the individual pairs are shielded. Special LON bus cable can be used for highly demanding requirements.

11.3 Bus Termination
Additional bus terminators are required for bus topologies, and where repeaters are utilized. These can be purchased as auxiliary LON component U1664 in top-hat rail mount housing. Each unit includes a one-ended and a two-ended bus terminator.

12.1 Network Interface
So-called binding is generally required in order to enable communication amongst LON devices. This means that network-variable outputs are connected (bound) to networkvariable inputs with the help of a tool. Binding is not required for the U1604, which significantly simplifies installation. The nodes are addressed via the neuron ID (LON ID). The neuron ID is a twelve digit number which is printed on the device, and which can be queried via the display at the A2000. The channel function is configured with the mode command (CMODE). The desired values are selected with the sub-channel command (LonCHANNEL). Selected values and any error messages generated by the LON devices are queried cyclically (polling).

12.2 Functions
Acquiring Energy and Power Values (mode: LON, CMODE = 4 LON) The U1604 continuously acquires meter readings and power values from the LON devices. A delta value is generated based on the current meter reading and the previous value, which is added to Etot and Eint. The current meter reading is stored to non-volatile memory for use in generating the next delta value. Only positive delta values are taken into consideration. Special feature for U1660 and U1661: These devices are not equipped with a non-volatile memory. If supply power to any given LON data logger is interrupted, it starts counting again from zero. Meter readings acquired after this point in time are smaller than the recorded energy value, and thus no delta value is generated. In order to assure that this energy is not ignored, the first value after a power failure is saved as the previous value, and is used as a basis for generating the next delta value.
Acquiring Analog Values (mode: LON-ANA, CMODE = 5 LonA) LON device network variables can also be acquired as analog values. This operating mode is especially useful for the innumerable values read out by the A2000 and the DME400. Values are not integrated in this case.
Acquiring Analog Values with Integration (mode: LON-PE, CMODE = 6 L-PE) If the analog value represents power, energy is calculated by means of integration.
Binary Inputs and Outputs (mode: LON-INP, CMODE = 7 LonI or LON-REL, CMODE = 8 LonR) Binary inputs can be queried with the U1660 meter polling module, and the OCL210 relay output module is capable of switching relays.
