HTG410H
Communication Module
7.4.1 Setting of communication module
The Modbus parameters are adjustable on the front panel by rotary
switches:
• Modbus address from 1 to 99
• Parity
• Speed in BAUD
The Modbus communication module integrate a 120 Ω resistor to
integrate a termination impedance into the Modbus chain.
This resistor can be activated / deactivated via a switch in front.
There are two versions: with or without input and output digital
inputs.
HTC310H: without input and output contacts.
HTC320H: with 2 digital inputs contacts and 2 contacts digital
outputs.
Default setting of the communication module
Modbus address = 1
Bus speed: 19200 BAUD
Parity: pair
120Ω resistance: ON enabled
