l Selecting from the Registered Variables
If the variables that are used in the program are registered before you finalize on the Controller
configuration and the external devices to connect, you can select and assign variables to the I/O
ports for the safety I/O terminals as long as the variables are registered in the variable table.

On the Safety CPU Unit Setup and Programming View, select Configurations and Setup and
double-click I/O Map.
The I/O Map will be displayed.

Select an I/O port and select a user-defined variable from the list of variables that are regis-
tered in the variable table to assign the variable to that I/O port.
Additional Information
If the I/O terminals on the Safety I/O Units are set to Dual Channel Mode, the device variable
can only be assigned to an even-numbered terminal.
