Hello Team,

I have tried to communicate Modbus TCP/IP device (Versadac Controller by Eurotherm) to codesys, but i could not read the Modbus registers data in Codesys.

Other Modbus devices is communicating to codesys but Versadac controller only not communication.

Communication status is healthy and there is no error count.

Codesys Version is V3.5 SP16 Patch 1

Check below screenshot for your reference.

Pl check and let me the solution.

Hi,

do you use your %IW in the Programm?

If not you will not receive the current values. For that you have to activate it in your controller settings:
