Hi all, I need to write program to read/write data between SLC500 and Controllogix via enthernet, For my knoledge, it can use MSG instruction, but I never use it before. Does anyone have any information or experience about that? Thanks a lot!
In the control logix you need to create the path directly into the MSG instruction.
ie "LocalENB,2,192.168.0.1" will get you straight to 192.168.0.1 through your 1756-ENBT module.
secondly, you need to use Logic->Map PLC/SLC Messages to map a file number to a tag name for the SLC to Control Logix comms.
