1. From the Logic menu, select Map PLC/SLC Messages.
2. Specify this information:
The following table shows example source and destination tags and elements
for different controller combinations.
For: In this field: Specify: For example:
PLC-3, PLC-5, and
SLC controllers File Number Type the file number of the data table in the
PLC/SLC controller. 10
Tag Name Type the array tag name the local controller uses to refer
to the PLC/SLC data table address. The tag must be an
integer array (SINT, INT, or DINT) that is large enough for
the message data. array_1
PLC-2 controllers Tag Name Type the tag name to be the PLC-2 compatibility file. 200
TIP
You can map as many tags as you want to a PLC-3,
PLC-5, or SLC controller. You can map only one tag
to a PLC-2 controller.
Type of MSG Instruction: Example Source and Destination:
PLC-5 writes to DriveLogix
SLC writes to DriveLogix
SLC 5/05
SLC 5/04 OS402 and above
SLC 5/03 OS303 and above
source element N7:10
destination tag “array_1”
The PLC-5, PLC-3, and SLC controllers support logical ASCII addressing so you do not
have to map a compatibility file for MSG instructions initiated by a PLC-5, PLC-3, or SLC
controller. Place the DriveLogix tag name in double quotes (“).
You could optionally map a compatibility file. For example, if you enter 10 for the
compatibility file, you enter N10:0 for the destination tag.
