I am trying to connect to a Carel IR33 controller. I have the following hardware:
USB-RS485 converter - CVSTDUMOR0
Carel serial adapter - IROPZ48500
Carel IR33 Controller
I have installed the Carel USB drivers and am using Mango 1.11.0.
I have been able to test that the hardware is working OK by using Carel's Comtool software and can connect and change any parameter in the controller.
When I try a Modbus node scan on a Modbus serial data source it doesn't find any nodes nor does the read data or locator test find anything.....Mango just returns "No response from slave 1"
Am I missing something or is this not possible?
Any help greatly appreciated.
