Hi Guys,

I’m trying to connect to a old PLC5/250 through ControlNet and DH+. But I’m not sure if my connection path is correct and whether our arrangement is even supported by ignition. Could someone have a look at this for me please?

Below is the path to PLC 5 and my connection path is 1,10,2,5,1,4,3,1

I believe you just need to add a 0 to the end of the path to reach the processor
