Good day. I am trying to read some values from a Modbus TCP slave. However, I am unable to get any value. The ComState show connected and the byModbusError show RESPONDE_SUCCESS. I am not sure where I went wrong.
Another question is, currently, I run the project on my Raspberry Pi without the CODESYS Control for Raspberry Pi MC SL license. Is the Modbus TCP and the GPIO can work in the demo mode for 2 hours?
