1 Description

Introduction

This document describes the integration of Modbus RTU and Modbus TCP installations into BACnet MSTP or BACnet
IP compatible devices and systems using the Intesis BACnet Server – Modbus Client gateway.

The aim of this integration is to make accessible Modbus system signals and resources from a BACnet based control
system or device, as if it was a part of the own BACnet system and vice-versa.

The gateway acts as a BACnet/IP Server or BACnet MSTP device in its BACnet interface, allowing other BACnet
devices to perform subscription (COV) requests and reads/writes to its internal points. From the Modbus point of
view, Intesis simulates a Modbus RTU Master device and or Modbus TCP Client device. Readings of the Modbus
slave device(s) is performed by Intesis by automatic continuous polling.

Configuration is carried out using the configuration software IntesisTM MAPS.
This document assumes that the user is familiar with BACnet and Modbus technologies and their technical terms.

Functionality

From the Modbus system point of view, after the start up process, Intesis reads continuously the points configured
to be read in the Modbus TCP Server and/or Modbus RTU Slave devices and updates in its memory all the values
received from the Modbus system.

There are 2 available ports for Modbus RTU integration. When enabling this functionality in Intesis MAPS, each RS­485 port (Port A and Port B) integrates up to 32 Modbus RTU devices (up to 64 devices in total) without the need of
additional repeaters to 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.

For more information about product ports and connections please see Section 6. Connections.
The default configuration is Port A: Modbus RTU and Port B: BACnet MSTP.
From the BACnet system point of view, after the start up process, the gateway listens for any subscription (COV)

request, serves any polling request, or performs any writing request of its internal points received from the BACnet
system. The values received from BACnet are immediately written in the associated register of the corresponding
Modbus TCP Server or Modbus RTU Slave device.

All the Modbus registers in the slave devices is associated to a BACnet object, with this, all the Modbus system (all
the slave devices) is seen as a single BACnet device with many objects from the BACnet system point of view, each
object corresponding to a Modbus slave/register address.

When a new value is read from Modbus for a given register, the new value is updated in the gateway's memory and,
if this signal is associated to a BACnet active subscription then the new value will be sent to the subscripted BACnet
device(s).

In the continuous polling of the Modbus devices, if a non-response of the BACnet device is detected, the
corresponding virtual signal inside Intesis will be activated indicating communication error with the Modbus device.
These virtual signals indicating communication status in real time with the Modbus devices are also accessible from
BACnet, like the rest of the points of the gateway.
