Hi,

Does anybody want to share some simple example using MODBUS_MASTER and MODBUS_COMM_LOAD with more two or more ports? In case we have more than one RS485 line, I am having trouble with correct initialization and start of functions. Sometimes, they go OK after PLC restart, but sometimes I am getting errors.

Please, I don't need explantation since I have already read everything, used all Siemens official examples, tried I don't know how many different scenarios, but still have a problem.

Example pleeeeeeeeeeeese! :)

Best regards,
