Unit Replacement
• Make sure that the required data, including the user program, configurations, settings, and varia-
bles, is transferred to a CPU Unit that was replaced and to externally connected devices before re-
starting operation. Be sure to include the tag data link settings and routing tables, which are stored
in the CPU Unit.

fsets are retained in the CPU Unit as absolute encoder information.
