CP2E CPU Unit Software User’s Manual(W614)
Applications of the bits and words in the Auxiliary Area are predefined. Ladder programs can be simpli-
fied and controllability can be improved by effectively using the bits and words in this area.
•
Some words or bits are set automatically by the system and others are set and manipulated by the
user.
The Auxiliary Area includes error flags set by self-diagnosis, initial settings, control bits, and status
data.
•
Words and bits in this area can be read and written from the program or the CX-Programmer.
•
The Auxiliary Area contains words that are read-only (A0 to A447) and words that can be read and
written (A44
8
to A959).
•
Even the read/write bits in the Auxiliary Area cannot be force-set and force-reset continuously.
