Arduino Mega 2560 to Ignition

I’ve been tasked to connect an Arduino to Ignition via ModBus TCP. It attempts to connect but fails and does not report to the log.

We have tried setting the arduino up as server and client, and the IP Address and port has been checked. The device can be pinged from the ignition server

Ignition’s native Modbus driver is only a client. So the arduino would have to be set up as a server.

If you try my Advanced Modbus driver, you can try either way. (:
