Started receiving this error on some of the C-More HMIs that are part of the plant network. There does not seem to be any issues with functionality.
No PLC programs were changed.
Only three of about 32 PLCs on the Ethernet network are creating the errors. Once is a Micrologix 1100 and the other two are SLC 5/05. They are connected to the HMIs via an unmanaged switch, which was changed
Rebooting the entire network didn't help.
I went through all of the PLC programs to ensure there were no tags that referenced addresses not present in the PLC programs and didn't find any
All devices can be pinged fine, with no time-outs
Any suggestions?
