Hi,

I'm trying to reach Allen Bradley CompactLogix 5380 PLC with Node-Red and ETH-IP node.

PLC IP: 10.100.1.20 Slot: 0

Ping OK, Studio 5000 connection OK, PLC in run mode, process control active.

If I configure the ETH-IP node normally, I get error:

Error communicating with the PLC: {"generalStatusCode":4,"extendedStatus":[0]}

This is a software tag FT_01. I can read it with another IIoT Gateway, but I need to add the path: PROGRAM:MainProgram.FT_01

Is there a way to add the program path? BTW, I'm doing this via Node-Red ETH-IP Node.

Hi @SaiQmon, I had the same problem with our Contrologix L81 Controller. I had a miss match with the Tag Name, I checked them a couple time, I didn't saw the fault. I got the fault also, when I set up a new List, that also doesn't work, and Arrays do also trouble.

I hope that will help you to solve the problem.
