The Error -22 is caused when a ForwardOpen fails, which basically means it could not connect to the PLC or it refused to allow an Ethernet/IP connection.Archie, I tried this out today and I was able to connect through the IP address, it worked this morning and now it's not connecting. I have an AB ML1500 with NetIP. I'm getting a "Unknown Message --22".

First one I am using T4:0 as per your example. The second N7:0. It reads both, but only after adding the second do I start receiving the following error:
