Define an I/O Status File
The I/O status file stores data for the controller’s I/O rack configuration
tables. The I/O status from each remote I/O rack requires two words. These
two words store the reset, present, inhibit, and fault bits for each rack.
To define an I/O status file, enter an unused integer file number (9-255) in the
I/O status file field (S:16) of the controller configuration screen. If you do not
want to use I/O rack configuration tables, enter 0. However, if you want to
use the autoconfiguration option to create your scan list, you must define an
I/O status file. Use the controller configuration screen in your programming
software:
