3-5 AR (Auxiliary Relay) Area
AR word addresses extend from AR 00 to AR 27; AR bit addresses extend from
AR 0000 to AR 2715. Most AR area words and bits are dedicated to specific
uses, such as transmission counters, flags, and control bits, and words AR 00
through AR 07 and AR 23 through AR 27 cannot be used for any other purpose.
Words and bits from AR 08 to AR 22 are available as work words and work bits if
not used for the following assigned purposes.
