Hi guys,
We recently had the hard drive fail on our PLC laptop. Once out IT guy loaded all of our data on the new HDD I went to work re hosting our activations and enabling them on the new HDD. An issue has come up where on one particular device, I am unable to see the 1756-A17/B backplane beyond the 1756-ENBT module in RSLinx calssic gateway. After i configure the driver, I am able to see that there is a 1756-ENBT module, and it even has the (+) to drop down the hierarchy, but the backplane never shows. Strange thing is, I have another machine on a 1756-EN2T module and i can explore the backplane with no issues at all. We had no connectivity issues before the hard drive crashed. I have everything else communicating.
I've scoured the forums and knowledge base and have tried everything that has been mentioned to fix this:
- downloaded all the EDS I could find pertaining to said cards/modules/backplane
- deleted the harmony files
Like I said, I can "see" there is a ENBT module, it knows what kind of module it is, there is no yellow question mark or red "x" just for whatever reason when i hit the drop down button the backplane isnt being found.
A push in the right direction would be muchly appreciated.
