Hello,
I'm using a rs485 opta that is reading Modbus RTU parameters from an external device. I have got this working and they are being stored on in a "modbus var" that is being mapped to a real memory address. I would like to be able to read and edit these over TCP. I dont believe these memory locations are actually accessible externally? Is there a way of mapping these to the read and write registry. What is the best way of doing this on the Arduino PLC IDE?
Many thanks,
jonthe
