I've purchased an Arduino Opta Lite and am trying to connect it to Ignition. Has anyone had any success connecting an Arduino Opta to Ignition (or similar SCADA) using Modbus TCP through the PLC IDE? If so can you please show how you have done it. I've followed the advice outlined in threads like this and have been unsuccessful:
I've created some paramaters in the public objects which I've tried to add to a tag in Ignition at HR1/HR2 etc... which don't work. Ignition is able to detect and connect to the Arduino Opta. However in the Arduino IDE I am getting the following on the serial monitor:
Recieved ModbusTCP Connection from [the device that is hosting Ignition's IP]
Modbus Exception Code: 10
MbS Channel 604283544 invalid header
Have experimented around and I can't figure it out. I've followed all the tutorials from ignition and I am able to successfully configure the Arduino Opta using ModbusTCP connection itself (so I think the ModbusTCP is configured correctly). I'm new to PLCs so it's definitely possible I've made a mistake in configuration. If anyone has any advice on how to establish connection please let me know. I'm going to try and source an Arduino Opta WiFi and try that instead. Cheers.
