Factory IO with Twincat 3

Good day, I have a problem connecting to factory io via modbus server. I did everything that was needed but I can’t see the connection. No errors pop up. I downloaded the modbus package from the beckoff website. Help!

Hi @83745, welcome to the forum!

I took a look at the images you shared and the IP Address set in Factory I/O is not the same as the one you set in TwinCat.
I also noticed that you set the port to 505 but in TwinCat, the variable nTCPPort has the value 502.

I hope this helps
