I am having a problem communicating my PLC with Drive via Modbus connection. I start by opening the port and there is no problem, but then when I want to use the Modbusmaster I fill in all the data correctly but it gives me two errors: 1 in the Trigger it does not allow me to assign any boolean to the switch and with the MCB I put an array in int format to fill in the communication fields but when compiling it marks Modbusmaster: argument expected. Do you have any idea what it could be?
