SLC Status File
This appendix lists the:
SLC processor status file overview
status file detailed word/bit descriptions
This appendix discusses the status file functions of the Fixed, SLC 500, SLC
5/01, SLC 5/02, SLC 5/03, SLC 5/04 and SLC 5/05 processors. The
processors function similarly, but the higher numbered processors utilize more
features. The tables in this appendix indicate which functions are supported by
each processor.
The appendix starts with an overview listing of the status file. A more detailed
description of each status word follows. Use the overview list to find the page
number of the detailed description.
Status File Overview
The status file lets you monitor how your operating system works and lets you
direct how you want it to work. This is done by using the status file to set up
interrupts, load memory module programs, and monitor both hardware and
software faults.
TIP
Do not write to status file data unless the word or bit
is listed as dynamic/static configuration in the
descriptions that follow. If you intend writing to status
file data, it is imperative that you first understand the
function fully.
