I'm searching for a Modbus expansion module capable of carries a set of digital I/O and an RS232 com port.
Could someone help me?
@mikeardy It's not good idea to mix RS232 and Modbus. You would need something like this for Modbus RTU RS485 extension https://www.unipi.technology/extension-modules-c13
