General Introduction

3. General Introduction
This Intesis® gateway allows you to integrate Serial and IP protocols easily. This document describes the available applications for this gateway: · Modbus® TCP & RTU Client to BACnet®/IP & MSTP Server · BACnet/IP & MSTP Client to Modbus TCP & RTU Server · BACnet/IP & MSTP Client to ASCII IP & Serial Server
IMPORTANT This document assumes that the user is familiar with BACnet, Modbus, and ASCII technologies and their technical terms.
NOTE Some sections provide general information common to all applications, while others highlight specific differences, capacities, or limitations.
In general terms, you must have a BACnet, Modbus, or ASCII control and monitoring system on one side and a Modbus or BACnet installation or device on the other side (only one at a time).
IMPORTANT The Intesis gateway can act as a server or client for BACnet and Modbus but only as a server for ASCII.
As always, the configuration process is fast and easy: 1. Launch the configuration tool. 2. Select the template. 3. Connect the Intesis gateway to the PC. 4. Adjust the configuration and signals to your project. 5. Send the configuration to the gateway.
And you are ready to go!

BACnet Server to Modbus Client

IN700-485 Series

4. BACnet Server to Modbus Client
4.1. Specific Gateway Introduction
This section describes the integration of Modbus RTU and/or Modbus TCP installations into BACnet IP or MSTP control and monitoring systems using the BACnet Server to Modbus Client application.
This integration allows a Modbus control system to access the signals and resources of BACnet systems as if they were part of the Modbus system itself and vice versa.
The gateway configuration is carried out through the configuration tool.

Figure 1. Integration of Modbus RTU or TCP devices into BACnet IP or MSTP control and monitoring systems
4.2. Functionality
From the Modbus point of view, the gateway continuously polls the installation or devices, storing in its memory the values of the points that you previously configured to be read. On the other hand, from the BACnet point of view, the control and monitoring system reads and writes those stored points.
This is possible because, inside the gateway, all Modbus registers of the server devices are associated with BACnet objects. This makes the BACnet control and monitoring system perceive the Modbus installation (all the server devices) as if it were a single BACnet device.
When the gateway polls the Modbus devices, if a non-response is detected, the corresponding virtual signal inside the gateway will be activated, indicating the communication error to the BACnet system.
The gateway has two EIA-485 ports for Modbus RTU integration: Port A and Port B. This function allows you to integrate up to 64 devices (32 in each port) with no additional repeaters in the network.
This functionality is disabled when BACnet MSTP is selected in Intesis MAPS, leaving only Port A available for Modbus RTU connectivity and Port B for BACnet MSTP devices.
By default, Port A is configured for Modbus RTU and Port B for BACnet MSTP.

This section describes the integration of BACnet MSTP and BACnet IP devices or installations into Modbus RTU or TCP systems using the Modbus server to BACnet client application of the Intesis gateway. This integration allows a Modbus system to access the signals and resources of BACnet devices as if they were part of the Modbus system itself and vice versa.
The gateway configuration is carried out through the configuration tool.

Figure 2. Integration of BACnet IP or MSTP devices into Modbus TCP or RTU control and monitoring systems
5.2. Functionality
From the BACnet point of view, the gateway continuously polls the installation or devices, storing in its memory the values of the points that you previously configured to be read. With the change of value (COV) system, the gateway can also subscribe to configured BACnet points, automatically receiving their values when they change. On the other hand, from the Modbus point of view, the control and monitoring system reads and writes those stored points.
This is possible because, inside the gateway, all BACnet objects of the server devices are associated with Modbus registers. This makes the Modbus control and monitoring system perceive the BACnet installation (all the server devices) as if it were a single Modbus device.
When the gateway polls the BACnet devices, if a non-response is detected, the corresponding virtual signal inside the gateway will be activated, indicating the communication error to the Modbus system as error registers.

BACnet Interface

IN700-485 Series

8. BACnet Interface
8.1. General Description
BACnet is a solid standard with many detailed concepts, but for this manual purposes, we will focus on the two most fundamental concepts:
· BACnet client, which is the device that sends service requests to the server. · BACnet server, which is the device that performs the requested service and reports the result back to the
client.
BACnet server devices are represented in the form of devices holding objects. Usually, every physical device corresponds to a logical one. The objects can be of different types depending on the data and functionality they represent: Analog input, Analog output, Digital input, etc.
NOTE · Output objects are objects meant to be written in the direction BACnet network to the device. · Input objects are meant to offer status information of the BACnet device. · Value objects are bidirectional.
Every object has different properties. The most meaningful one is the Present_Value property, which indicates the real value of the object. Also, the gateway uses this property to read and write values. Every object of the same type in a device is identified with its associated object instance.

USER MANUAL Version 1.2

BACnet Client

8.2. BACnet Client
8.2.1. Description
The gateway implements a single BACnet object of its own: its BACnet Device Object, which contains its BACnet Device Identifier and basic properties of the gateway as a BACnet device (name, firmware version, etc.).

NOTICE When acting as a client device, the Intesis gateway is classified under the device profile of a BACnet Application Specific Controller (B-ASC). For further details, check out the product website for the BACnet client PIC statements.

The gateway emulates a client device in the BACnet system. These are the possible BACnet objects supported by the Intesis gateway:

Object Type Analog Input Analog Output Analog Value

Property Present Value Present Value Present Value

Binary Input Binary Output Binary Value

Present Value Present Value Present Value

Multistate Input
Multistate Output
Multistate Value
Accumulator
Loop

Present Value Present Value Present Value Present Value Present Value

Description Analog signal, for example, Ambient temperature Analog signal Analog signal, for example, Temperature set point value Digital signal, for example, ON/OFF status Digital signal, for example, ON/OFF command Digital signal, for example, ON/OFF status/ command Multistate signal, for example, Working mode status Multistate signal
Multistate signal, for example, Working mode command

Every signal is identified with its associated Device + Object Type + Object Instance.

IMPORTANT Though BACnet IP and BACnet MSTP physical layers are supported, only one physical layer can be used at a time, i.e., if communicating to BACnet using BACnet IP, BACnet MSTP cannot be used, and vice versa.

NOTE Using the configuration tool, it’s possible to scan the BACnet network for available devices and their objects, which can later be directly added to your configuration. This feature facilitates the configuration process, avoiding entering them manually.

Every signal of the Intesis gateway can have several objects. These objects and their properties can be configured with the configuration tool.
Depending on the field device protocol, you can define the signals using one of the following options:
· Configuring them manually for each or multiple signals at the time. · Importing a file with the signals of the field devices. · Scanning the network of the devices if this is supported.
Example 1. Signals compatibility You can choose an object from the BACnet server column that is compatible with this signal. For example, a writable register in the Modbus device can be an output object type on the BACnet server side; a readable and writable register can be a value object type, etc.

NOTICE The configuration tool provides default templates that make this signals assignment process easier. Also, you only have to click the Check table button on the bottom right corner of the window to know if everything is correct or if there’s some mistake. The project is also automatically checked before you transfer it to the gateway.
All objects definition, BIBBs, and details about the implementation can be found on the BACnet server PICS on the product website.

USER MANUAL Version 1.2

BACnet Server

IN700-485 Series

8.3.2. BACnet IP
The UDP communication port is the main setup parameter for BACnet IP, besides basic IP settings (IP, netmask, default gateway). The Intesis gateway uses the 47808 (0xBAC0) port by default, which you can change through the configuration tool.
When using BACnet IP, the gateway can also act as a foreign device to communicate with devices in another network domain. Alternatively, you can set it as a BBMD (Bacnet IP Broadcast Management Device). This functionality facilitates the communication of devices placed in other networks with the devices in the gateway network.
IMPORTANT BACnet IP and BACnet MSTP communication can not be used simultaneously.
8.3.3. BACnet MSTP
When you choose BACnet MSTP (serial communication), you have to use the configuration tool to associate the gateway with a MAC address within the MSTP network segment.
Baud rates supported for MSTP line are: 9600, 19200, 38400, 76800, 115200, or Autobauding (autodetect).
Standard wiring guidelines for EIA-485 apply to the BACnet MSTP line.
IMPORTANT BACnet MSTP and BACnet IP communication can not be used simultaneously.

Modbus Interface

9. Modbus Interface

9.1. General Description
The Modbus protocol is an application-layer messaging protocol developed by Modicon in 1979. It is used to establish master-slave/client-server communication between intelligent devices over different types of buses or networks. The Intesis gateway supports Modbus TCP and RTU.
Modbus is a request/reply protocol and offers services specified by function codes. Modbus function codes are elements of Modbus request/reply PDUs (Protocol Data Unit).
9.2. Modbus Server Interface
9.2.1. Description
The gateway acts as a server device in its Modbus interface, which can be:
· The Ethernet port for Modbus TCP. · The EIA-485/EIA-232 ports for Modbus RTU.

NOTICE Modbus RTU and TCP modes can be active in the gateway one at a time or both simultaneously.

To access the gateway’s points and resources from a Modbus client device, you must specify as Modbus register addresses those configured inside the gateway corresponding to the signals on the field device protocol.
9.2.2. Functions Supported

NOTICE This part is common for both Modbus TCP and Modbus RTU.

If poll records are used to read or write more than one register, the range of addresses requested must contain valid addresses; if not, the Intesis gateway will return the corresponding Modbus error code.
All registers are of 2 bytes, even if they are associated with signals of bit type on the other protocol’s side. Its content is expressed in MSB .. LSB.1
Modbus error codes are fully supported. They are sent whenever a non-valid Modbus action or address is required.
1MSB: most significant bit; LSB: less significant bit

USER MANUAL Version 1.2

Modbus Server Interface

IN700-485 Series

9.2.3. Modbus RTU
Using the configuration tool, you can set these parameters:
· Baud rate: 1200, 2400, 4800, 9600, 19200, 38400, 56700 and 115200 bps · Data Bits: 8 bits · Parity: none, even, or odd · Stop Bits: 1 and 2 bits · Modbus server address · Physical connection (EIA-232 or EIA-485)
IMPORTANT · EIA-232 connector uses RX, TX, and GND lines. · EIA-485 connector uses B-, A+, and SNGD.
9.2.4. Modbus TCP
Modbus TCP communication is characterized basically by the embedding of the Modbus RTU protocol into TCP/IP frames, which allows faster communication and a longer distance between client and server devices in comparison with RTU communication over a serial line. Another benefit is using common TCP/IP infrastructure in buildings and transmitting over WAN or the internet. It also allows the coexistence of one or more clients and, of course, one or more server devices in a given network, all interconnected through a TCP/IP-based network.
Use the configuration tool to configure the IP settings of the gateway (DHCP status, own IP, netmask, and default gateway) and the TCP port.
NOTE The default port is 502.

Modbus Client Interface

9.2.5. Modbus Server Interface Points Definition
The Modbus registers are fully configurable through the configuration tool; any point in the gateway can be freely configured with the desired Modbus register address.
Every point defined in the gateway has the following Modbus features associated with it:

Feature #Bits
Data Coding Format
Byte Order
Register Address Bit inside the register
Read/Write

· 1 bit · 16 bits · 32 bits

Description

· 16/32 unsigned · 16/32 bits signed (one’s complement ­ C1) · 16/32 bits signed (two’s complement ­ C2) · 16/32 bits Float · 16/32 bits Bitfields · Error comm.

· Big Endian · Little Endian · Word Inverted Big Endian · Word Inverted Little Endian

The Modbus register address inside the server device for the point.

Bit inside the Modbus register (optional). The Intesis gateway allows bit decoding from generic 16 bits input/holding Modbus registers.

Some devices use the bit coding into 16 bits input/holding Modbus registers to encode digital values. These registers are generally accessible using Modbus function codes 03 and 04 (read holding/input registers).

0: Read 1: Write 2: Trigger

9.3. Modbus Client Interface
9.3.1. Description
The Intesis gateway acts as a client device in the Modbus TCP network, Modbus RTU client, or both.

IMPORTANT Other Modbus devices connected to the network communicating with the gateway must always be server devices.
The gateway supports communication with up to five Modbus TCP server devices.
For every defined point belonging to a particular Modbus TCP server device, a server address from 0 to 255 can also be freely configured. This feature offers great flexibility for installations. For example, when integrating several Modbus RTU server devices connected in a serial line, with an RTU/TCP converter on top of this serial line, it enables access to the RTU server points through TCP/IP. In this case, the RTU/TCP converter communicating in TCP identifies the destination of the point (server address in the RTU network) by the contents of the server address field.
Modbus TCP server devices are characterized by their IP address and predefined registers address map. This address map specifies the address, type, and characteristics of the Modbus server device’s internal points (commonly called registers). These registers are accessible using the Modbus TCP protocol.
Communication parameters of the Intesis gateway (IP address, netmask, default router address, and TCP port) are fully configurable to adapt to any IP network and server device.

USER MANUAL Version 1.2

Modbus Client Interface

IN700-485 Series

The Modbus TCP protocol defines different function code types to read/write different register types from the Modbus devices. It also defines different data formats to encode values.
Also, the data encoding used for 16 bits registers (big-endian or little-endian) can be configured in the Intesis gateway. This is the byte order for data encoding (MSB..LSB or LSB..MSB)2. Although specified as big-endian in the Modbus protocol specification, this data encoding varies depending on the manufacturer/type of server.

ASCII Interface

10. ASCII Interface
10.1. Description
The Intesis gateway can be connected to any ASCII-enabled device via its EIA-232, EIA-485, or TCP/IP (Ethernet) connectors, supervising and controlling its internal points through this interface by using simple ASCII messages.
When the gateway receives a new value for a point from the other protocol system, its ASCII interface sends the corresponding message indicating the new value to the ASCII system.
IMPORTANT · This functionality is only possible if the point is configured to send these “spontaneous messages.”
If it doesn’t, the new value will remain available in the gateway for a later poll of the ASCII system. · You can configure this behavior for every gateway point through the configuration tool.
10.2. ASCII Serial
The ASCII interface and the ASCII master device serial connection type must be the same.
10.3. ASCII TCP
The Intesis gateway allows the configuration of:
· TCP port (5000 by default) · IP address · Subnet mask · Default router address
10.4. Address Map
The ASCII address map is fully configurable; any point in the gateway can be freely configured with the desired internal register address.
