1.1. DESCRIPTION
T203PM is a transducer for measuring AC/DC current and voltage in an isolated way (insulation relating to the communication ports and the analogue and digital output), aimed at measuring energy (bidirectionally) that can be installed on DIN 46277 rail.
| Model | Description | Communication protocols |
| T203PM-MU | ModBUS 1PH Power Meter with analogue and digital output | ModBUS RTU |
Measuring the voltage and current of the network, the instrument allows to measure the RMS values, instantaneous powers and energies of the devices to be monitored.
The 1.3kHz input measurement band guarantees the measurement of voltage and currents with harmonic components up to the twenty-first (at the mains frequency of 60 Hz). The use of this device is compatible with single-phase inverters.
The list of measurements made available by the tool is provided below:
- TRUE RMS AC VOLTAGE and CURRENT MEASUREMENTS (TRUE EFFECTIVE VALUE)

2.1. CONVENTIONS
The device provides the measurement values of the powers on all 4 quadrants. The conventions for the signs of the measurements used in the product are summarized in the following image:

Where:
quadrant Q1 relates to an inductive load with imported (absorbed) active energy, classic use case.
quadrant Q2 relates to a capacitive load with exported (generated) active energy.
quadrant Q3 relates to an inductive load with exported (generated) active energy.
quadrant Q4 relates to a capacitive load with imported (absorbed) active energy.
2.2. INSTANTANEOUS VALUES PROVIDED and MINIMUM -MAXIMUM ABSOLUTE VALUES
The following table provides the list of instant measurements provided by the instrument; all instantaneous measurements have a minimum and maximum memory that can be reset via the ModBUS CLEAR MIN/MAX command (refer to the COMMAND register in the register list)
| Voltage | V |
| AC/DC (+/-) current | I |
| Active power (+/-) | P |
| Reactive power (+/-) | Q |
| Apparent power (+/-) | S |
| Power Factor | PF |
| Frequency | F (frequency measured on the mains voltage) |
| THD | % (measured on current) |
2.3. ENERGY METERS and INITIAL SETTINGS
The following table lists the 64-bit integer counters whose values are saved in Fe-RAM (memory writable an unlimited number of times):
| ACTIVE ENERGY [Wh/10] (TOTAL (+/-)) |
| REACTIVE ENERGY [VARh/10] (TOTAL (+/-)) |
| APPARENT ENERGY [VAh/10] (TOTAL (+/-)) |
To these 64-bit counters corresponds the value of the energies in 32-bit floating point value as shown in the following table (refer to the table of ModBUS registers at the end of the manual):
| MEASUREMENT | 64BIT INTEGER REGISTER | FLOAT32 REGISTER |
| ACTIVE ENERGY | EN_INT_ACTIVE [Wh/10] | MISEN_F_ACTIVE [Wh] |
| REACTIVE ENERGY | EN_INT_REACTIVE [VARh/10] | MISEN_F_REACTIVE [VARh] |
| APPARENT ENERGY | EN_INT_APPARENT [VAh/10] | MISEN_F_APPARENT [VAh] |
The ability to customize the 64-bit energy values is also made available to the user by following the following procedure which uses the sending of ModBUS commands to first unlock the write protection and then to finalize the writing in non-volatile memory:
- In the COMMAND register, send the ENABLE WRITE CUSTOM ENERGIES command
- Now the instrument no longer integrates the energies into memory; it is therefore possible to write the desired initial values in the 64bit integer registers relating to the ACTIVE / REACTIVE / APPARENT energies
- At this point it is possible to complete the writing using the ModBUS WRITE CUSTOM ENERGIES AND REBOOT command.
If, on the other hand, one only wishes to bring the values of these counters to zero, execute the ModBUS CLEAR ENERGIES command
Note:
- During normal operation, energies are saved in non-volatile memory once per second
- When customizing the energies, once the non-volatile write protection has been disabled, the device can return to normal operation using the ModBUS WRITE CUSTOM ENERGIES AND REBOOT or REBOOT commands.

4.1. ANALOGUE AND DIGITAL OUTPUT
The analogue and digital outputs can be associated respectively to one of the instantaneous measurements provided between VOLTAGE / CURRENT / ACTIVE P. / REACTIVE P. / APPARENT P./ FREQUENCY / PF / THD. Below you can see the configuration details separately for the analogue and digital output.
4.1.1. Analogue output
The analogue output is able to provide a voltage in the 0 ÷ 10V range; the analogue repetition of a measurement is performed by defining:
- A range of the input measurement (beginning and end of the measurement scale)
- A range of the output voltage to which the measurement will be associated (Start and end of the output scale)
The image below graphically illustrates the values described above

8.1. NUMBERING OF “0-BASED” OR “1-BASED” MODBUS ADDRESSES
According to the ModBUS standard the Holding Registers are addressable from 0 to 65535, there are 2 different conventions for numbering the addresses: “0-BASED” and “1-BASED”. For greater clarity, Seneca shows its register tables in both conventions.
ATTENTION!
CAREFULLY READ THE DOCUMENTATION OF THE MODBUS MASTER DEVICE IN ORDER TO UNDERSTAND WHICH OF THE TWO CONVENTIONS THE MANUFACTURER HAS DECIDED TO USE
8.2. NUMBERING OF MODBUS ADDRESSES WITH “0-BASED” CONVENTION
The numbering is:
| HOLDING REGISTER MODBUS ADDRESS (OFFSET) | MEANING |
| 0 | FIRST REGISTER |
| 1 | SECOND REGISTER |
| 2 | THIRD REGISTER |
| 3 | FOURTH REGISTER |
| 4 | FIFTH REGISTER |
Therefore the first register is at address 0.
In the following tables, this convention is indicated with “ADDRESS OFFSET”.
8.3. NUMBERING OF MODBUS ADDRESSES WITH “1 BASED” CONVENTION (STANDARD)
The numbering is that established by the Modbus consortium and is of the type:
| HOLDING REGISTER MODBUS ADDRESS 4x | MEANING |
| 40001 | FIRST REGISTER |
| 40002 | SECOND REGISTER |
| 40003 | THIRD REGISTER |
| 40004 | FOURTH REGISTER |
| 40005 | FIFTH REGISTER |
In the following tables this convention is indicated with “ADDRESS 4x” since a 4 is added to the address so that the first Modbus register is 40001.
A further convention is also possible where the number 4 is omitted in front of the register address:
| HOLDING MODBUS ADDRESS WITHOUT 4x | MEANING |
| 1 | FIRST REGISTER |
| 2 | SECOND REGISTER |
| 3 | THIRD REGISTER |
| 4 | FOURTH REGISTER |
| 5 | FIFTH REGISTER |
8.4. BIT CONVENTION WITHIN A MODBUS HOLDING REGISTER
A Modbus Holding Register consists of 16 bits with the following convention:
| BIT 15 | BIT 14 | BIT 13 | BIT 12 | BIT 11 | BIT 10 | BIT 9 | BIT 8 | BIT 7 | BIT 6 | BIT 5 | BIT 4 | BIT 3 | BIT 2 | BIT 1 | BIT 0 |
For instance, if the value of the register in decimal is 12300
the value 12300 in hexadecimal is: 0x300C the hexadecimal 0x300C in binary value is: 11 0000 0000 1100
So, using the above convention, we get:
| BIT 15 | BIT 14 | BIT 13 | BIT 12 | BIT 11 | BIT 10 | BIT 9 | BIT 8 | BIT 7 | BIT 6 | BIT 5 | BIT 4 | BIT 3 | BIT 2 | BIT 1 | BIT 0 |
| 0 | 0 | 1 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 1 | 0 | 0 |
8.5. MSB and LSB BYTE CONVENTION WITHIN A MODBUS HOLDING REGISTER
A Modbus Holding Register consists of 16 bits with the following convention:
| BIT 15 | BIT 14 | BIT 13 | BIT 12 | BIT 11 | BIT 10 | BIT 9 | BIT 8 | BIT 7 | BIT 6 | BIT 5 | BIT 4 | BIT 3 | BIT 2 | BIT 1 | BIT 0 |
LSB Byte (Least Significant Byte) defines the 8 bits ranging from Bit 0 to Bit 7 included, we define MSB Byte (Most Significant Byte) the 8 bits ranging from Bit 8 to Bit 15 inclusive:
| BIT 15 | BIT 14 | BIT 13 | BIT 12 | BIT 11 | BIT 10 | BIT 9 | BIT 8 | BIT 7 | BIT 6 | BIT 5 | BIT 4 | BIT 3 | BIT 2 | BIT 1 | BIT 0 |
| BYTE MSB | BYTE LSB | ||||||||||||||
8.6. REPRESENTATION OF A 32-BIT VALUE IN TWO CONSECUTIVE MODBUS HOLDING REGISTERS
The representation of a 32-bit value in the ModBUS Holding Registers is made using 2 consecutive Holding Registers (a Holding Register is a 16-bit register). To obtain the 32-bit value it is therefore necessary to read two consecutive registers:
For example, if register 40064 contains the 16 most significant bits (MSW) while register 40065 contains the least significant 16 bits (LSW), the 32-bit value is obtained by composing the 2 registers:
| BIT 15 | BIT 14 | BIT 13 | BIT 12 | BIT 11 | BIT 10 | BIT 9 | BIT 8 | BIT 7 | BIT 6 | BIT 5 | BIT 4 | BIT 3 | BIT 2 | BIT 1 | BIT 0 |
| 40064 MOST SIGNIFICANT WORD | |||||||||||||||
| BIT 15 | BIT 14 | BIT 13 | BIT 12 | BIT 11 | BIT 10 | BIT 9 | BIT 8 | BIT 7 | BIT 6 | BIT 5 | BIT 4 | BIT 3 | BIT 2 | BIT 1 | BIT 0 |
| 40065 LEAST SIGNIFICANT WORD | |||||||||||||||
32 = + ( ∗ 65536)
In the reading registers it is possible to swap the most significant word with the least significant word, therefoit is possible to obtain 40064 as LSW and 40065 as MSW.
8.7. TYPE OF 32-BIT FLOATING POINT DATA (IEEE 754)
The IEEE 754 standard (https://en.wikipedia.org/wiki/IEEE_754) defines the format for representing floating point numbers.
As already mentioned, since it is a 32-bit data type, its representation occupies two 16-bit holding registers.
To obtain a binary / hexadecimal conversion of a floating point value it is possible to refer to an online converter at this address:
http://www.h-schmidt.net/FloatConverter/IEEE754.html

Using the last representation the value 2.54 is represented at 32 bits as: 0x40228F5C
Since we have 16-bit registers available, the value must be divided into MSW and LSW: 0x4022 (16418 decimal) are the 16 most significant bits (MSW) while 0x8F5C (36700 decimal) are the 16 least significant bits (LSW).

By adding offset 1000 to the register it is possible to obtain the 32-bit swapped values, for example the floating point current measurement register:
| 40107 | 106 | MISRMS_F_I | MSW | Current measurement RMS [A] | RO | FLOAT 32 BIT |
| 40108 | 107 | LSW |
The same register can also be found at 41107-41108 swapped:
| 41107 | 1106 | MISRMS_F_I | LSW | Current measurement RMS [A] | RO | FLOAT 32 BIT |
| 41108 | 1107 | MSW |
