Hi everyone!
Hope you all are doing great!
We have a really strange issue with comms between Wonderware and a controllogix L62, we use an Ethernet IP module to gather all data.
Usually we leave always the key switch in REM mode, so we can always perform changes online, but for some reason, suddenly the communication with Wonderware was lost...
We werent able to find any problem with the communications, we ping the Ethernet module and was responding, everything seem ok!
Then randomly, one maintenance guy say "I found the problem" and he switch the key to RUN, and as strange it may appear wonderware was back.
We tested switching back to REM mode and again wonderware communication was lost... Really I have no clue on why this is happening.
This is the only Controller with this issue, all the other PLC´s are running in REM mode no problem.
For me this makes no sense since the comms are made using DASABCIP Server, which as far as I know its not triggered to change its state with the key switch.
Any ideas on what possibly could be happening?
Thanks in advance.
Happy new year!
