  @havor wel... you could. in case of Neuron, you would be dealing with a warranty voided unit and possible heat issues caused by the new design of RPi4.

  Hello @loggeduser, yes, you can. There are three ways how to communicate with IOs from your program: ModbusTCP server - local process running on port TCP/502 making the IOs available via Modbus coils and registers. You can read more about the Modbus Registers Maps EVOK - all sorts of web APIs (json, rest, websocket,...), more information here SysFS - IOs are made available through a virtual filesystem, more information here But it depends on which unit you use. Best regards, Martin
