I recently had to change the way my MSG instructions were connecting via ethernet radios; I originally had the remote PLCs in the I/O of the "master" PLC, but it was crashing the connection because of too much data. The solution was to manually tell the MSG instruction where to connect not by "browsing" to the I/O list, but rather to type out the IP address of the remote PLC.
The string in the path line at the "master" PLC is:
where:
Can someone clarify what that '2' means, and what (if any) other options there might be? I read that simply "it should always be '2'" but want to make sure things are set up correctly. I did a decent amount of searching for Rockwell Technical Documents that might describe this path, but couldn't seem to find anything that described manually creating the path (as opposed to adding the remote PLCs to the master's I/O).
Oh, and this is a master ControlLogix to a remote CompactLogix.
Thanks!
The string in the path line at the "master" PLC is:
Code:
LCP_W_Ethernet, 2, 172.16.254.20
Code:
LCP_W_Ethernet - name of the master PLC's ethernet module
2 - something to the effect of "go out to the ethernet"
172.16.254.21 - IP address of the remote PLC
Oh, and this is a master ControlLogix to a remote CompactLogix.
Thanks!
