With Arduinos not really new but still kind of new Arduino OPTA, is it possible to connect to an ignition gateway? If so what are the steps necessary to do so?

IIRC, Arduinos can run a Modbus Server. That is likely the simplest way to connect. (But if they have enough horsepower to run an OPC/UA server, that would be better.)

You could also do MQTT with an Arduino.

Would there be any benefits to running the OPTA, in more of a learning environment rather than industrial environment? All I can think of is cost. Has anyone tried the OPTA and or tried it with ignition?

I create a guide to connect Arduino PLC Opta or Portenta Machine Control to Ignition
