Hello, I have a code that I am using to communicate between an arduino UNO and LOGO V8 Siemens.
everything works 5*, but if the network cable connection is interrupted a few times I leave data in the LOGO the communication is lost, I have to disconnect and reconnect the arduino to recover the connection. what can i do to solve it?
