Re-Map Command
Use the Re-Map All command to clear all previous mappings and
automatically map all discrete and block transfer data to produced/consumed
data connections.
From the Map menu, choose Re-Map All.
IMPORTANT
If you change mappings, make sure you clear the output table in
the ControlLogix controller to prevent inadvertently writing to
an incorrect I/O location. If you leave a value behind in the
output table, it now points to something else on the Remote I/O
network. To clear the output table, set the outputs to 0. You
must also re-import the aliases.
