Map Tags
A Logix5000 controller stores tag names on the controller so that other
devices can read or write data without having to know physical memory
locations. Many products only understand PLC/SLC data tables formatting, so
the Logix5000 controller offers a PLC/SLC mapping function that lets you
map Logix tag names to memory locations.
• You have to map only the file numbers that will be referenced by
READ/WRITE messages requested from other controllers; the other
file numbers do not need to be mapped. For example, if another
controller will send a READ message only to N7, you need to map that
file.
• The mapping table is loaded into the controller and is used whenever a
“logical” address accesses data.
• You can only access controller-scoped tags (global data).
• For each file that is referenced in a PLC-5 command, make a map entry:
– Type the PLC file number of the logical address.
– Type or select the Logix5000 controller-scoped (global) tag that
supplies or receives data for the file number. (You can map multiple
files to the same tag.)
• For PLC-2 commands, specify the tag that supplies or receives the data.
IMPORTANT
The mapping function is particularly useful if your
Logix5000 controller is communicating with a PLC-5C
Series C/Revision L, Series D/Revision B, Series
E/Revision A or earlier.
