TCONTCCMHCM04A Wiring & Operating Instructions

The core function of the protocol converter is to convert Modbus protocol

into BACnet protocol, implement Modbus device integration into BACnet

network. That is, the gateway acts as a Modbus Master (master station) and

supports connection of 4 Modbus Slaver devices. TCONTCCMHCM04A is a

standard BACnet network device in the BACnet network, and the user can

map the device data points in the MODBUS network one by one to the data

points in the BACnet network. The gateway provides the BACnet service

interface, and the third-party BACnet Client software integrates the Modbus

Slaver device into the system through the gateway.
