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 Intesis
TM
MAPS.
This document assumes that the user is familiar with BACnet and Modbus technologies and their technical terms.
