Weintek's Codesys to Arduino Opta via Modbus RTU

Within this tutorial we demonstrate how to design a project that will allow Codesys to utilize device drivers within EasyBuilder Pro via the Modbus gateway in order to communicate with a Compact Logix PLC, Arduino Opta, and much more!

via Modbus TCP not RTU, right?

Hi @kampasp5,
In this case, CODESYS is talking to the HMI via Modbus TCP, but those requsts are being routed to the Opta via Modbus RTU. I hope this helps!
