  1. To manually assign a tag to an I/O Module channel (or Point), first add the I/O Module to an appropriate Cabinet or Equipment Panel (refer to Adding I/O Modules).

    All I/O modules in Wiring Manager are based on user defined catalog definitions.

    Note: I/O Module creation and channel assignment can also be done automatically by Importing I/O Allocations from an Excel file. Refer to Import I/O Allocations from Excel for further information.

  2. Once the I/O Module is positioned within the cabinet or panel, open the Terminations window and scroll to the specific I/O Module.
