We have an application where we're communicating between a 1769-SDN a 3rd party device. For the most part things work fine. We're reading maybe 8 or so addresses and writing to another 4. The issue is that periodically the data for a couple of the tags seems to get mixed up for a split second. So the data we're reading for tag1 ends up in tag2 and we see a constant (357) end up in tag 1. It only happens long enough to just see it flash on the HMI.
I'm not that familiar with Devicenet. Is there a good method for determining if the problem is on the PLC end or the 3rd party device?
