Sorry for cross posting from MrPLC, but I'm learning there is a lot more traffic here.
I have used PointIO a few times, but this is the first time using an IE4C. The wiring seems pretty straight-forward with Ch0 going to terminal 0 and the common is on terminal 4, if used.
I started off having a solid red status light for the network status, so I changed keying, reset the module, re-seated it and the TB3 base, and finally got a green status light for both, but I am getting ZERO data.
The channel faults are all 0, and the data is all 0, regardless of what I put on the input. I put a simulator between terminals 0 and 4 and the data still doesn't change from 0.
What's more strange is on occasion, I have gone into the IE4C properties and under the Module Info, it would sometimes show Unknown or "Control Techniques PLC" for the vendor. I have seen about 4 different serial numbers appear, and even the revision number has changed. If I hit reset module, it goes back to saying Allen Bradley with the correct serial number and correct revision number, but still does not give any data. I am assuming the module is bad and I have another one en route, but was curious if anyone could explain this because I haven't seen it on any type of module before.
And now, the replacement module has arrived and I am having the EXACT same issue, so unless I am very unlucky and received two bad modules, something else is going on.
These are on the CompactLogix backplane itself, and not on a 1734-AENT.
