I have a 1756-L62 that is sending a message to give a 1769-L24ER a permissive bit to run. This system has been working fine for about 2 years. Yesterday, I got the following error on the MSG instruction and could not resolve it no matter what I tried.
Error Code: 16#001f
Extended Error Code: 16#0000_0204
Error Text: Error processing connection related service
The L62 was a middle man between the L24ER and an L72 controller. I was able to route the message from the L72 to L24ER in order to give the machine permission to run and get production up and running again. It is working fine and can remain this way.
The question I have is what would cause this seemingly sudden error in the L62? I checked all network cables and connections and I had connection to each device on the network. I tried deleting the rung and the message tag from the L62 and starting over. The MSG is configured exactly the same in the L72 as it was in the L62 so I am not sure what the difference is. Any help to clarify and troubleshoot this issue would be greatly appreciated.
