Messaging Between PLC-5 or SLC 5/04 Controllers and ControlLogix Controllers
Configure Message Instructions
You must use RSLogix 5 software to configure the PLC-5 message instructions.
The following figure shows a message instruction necessary for this example.
IMPORTANT
If the ControlLogix controller in this example is the destination of a
PCCC-typed message, you must remember the following:
• When a PLC5, SLC500, PLC5/250, PLC3, or PLC2 sends a message to a
controller on ControlLogix, a mapping table is needed to be configured
in the Studio 5000 environment.
• In the Logic tab on the tool bar select Map PLC or SLC Messages
• The file number must be an integer type. Just write the file number in
the box. The whole file in the PLC or SLC controller will be used starting
with word 0.
• A tag must be created beforehand to accept the data with the proper
number of array elements.
• The destination tag in the PLC or SLC message is the file number
configured at the word level.
