ir33 Carel with Modbus
Carel ir33 refrigeration control unit with Modbus RTU
By John Ramirez on 5 August, 2018 - 12:18 pm

Hi, I have to try communicate the ir33 Carel refrigeration control unit using Modbus RTU using the tri-PLC but I starting to believe that model doesn't use Modbus RTU. I get the ModbusScan application to test it and nothing, however I can communicate with the ir33 Careluniversal unit.

There is a free application, the Comtool and it uses the Carel Protocol not the Modbus. Does anyone have some experience with this?

Best regards,
