I have a PLC5/40E that is reading a few FLOATs from a CompactLogix L35E. For some reason, twice over the last 24 hours, the IP address from the Multihop settings has dissapeared, resulting in the MSG instruction erroring out, with error code d3 (you formatted the control block incorrectly). When I go to the Multihop tab, instead of the correct IP, there's what looks like "lh" in its place.
This has happened twice now, both when no programming staff was on site, so I know for a fact this is happening on its own accord. We have added another message instruction to the PLC5 recently, but nothing directly related to this instruction has been changed. Has any one seen anything like this before? Any ideas where I should start looking to troubleshoot?
Thanks in advance!
