Hi all.
I have a stratix 5400 switch connected to a 1756-L83E controller via ethernet and I am trying to monitor the DLR network of the switch using the MSG instruction in a program. I input the data from the table on the manual to get the date for each service I am trying to obtain, but I am unsure what the "source element", "source length" and "what the communication path" for the MSG instruction should be?
Also, for each variable that I am trying to obtain such as the network topology, network status, etc, do I need a new msg tag for each msg instruction? I know the msg instruction has a destination element section where you select the tag you want the information to be sent to, but I tried using the same msg instruction just with a different destination tag but the destination tag changed on both msg instructions?
Im extremely new to PLCs so any help is appreciated. Thanks!
