5-4 Messaging Between PLC-5s or SLC5/04s and ControlLogix Controllers
Configure Message Instructions
You must use RSLogix 5 to configure the PLC-5 message instructions.
Figure 5.3 shows a message instruction necessary for this example.
Figure 5.3
For more information on how to configure message instructions using
RSLogix 5, see
page 3-9 or the RSLogix 5 online help.
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 RSLogix5000 program application.
· In the Logic tab on the tool bar select Map
PLC/SLC Messages
· The file number must be an integer type. Just
write the file number in the box. The whole file
in the PLC/SLC will be used starting with word 0.
· A tag must be created before hand to accept the
data with the proper number of array elements.
· The destination tag in the PLC/SLC message
would be the file number configured at the word
level.
