I am trying to use Codesys to connect by Modbus RTU to an Arduino UNO, I add the Modbus COM Port but when I try to add the master and the slave I don't have these options, I attach an image of the device manager. I am using Codesys 3.5 SP21.
On which plc you want to add this your screenshot show that it would work on Control Win ?
