Number Name Description Details Applicable CPU
D9010 Error step
Step number at which
operation error has
occurred
• When operation error has occurred during execution of
application instruction, the step number, at which the
error has occurred, is stored in BIN code. Thereafter,
each time operation error occurs, the contents of
D9010 are renewed.
Unusable with
A3H and A3M.
*1
D9011
Error step
Step number at which
operation error has
occurred
• When operation error has occurred during execution of
application instruction, the step number, at which the
error has occurred, is stored in BIN code. Since
storage into D9011 is made when M9011 changes from
off to on, the contents of D9010 cannot be renewed
unless M9011 is cleared by user program.
Usable with all
types of CPUs.
D9014
I/O control
mode I/O control mode
number
• The I/O control mode set is returned in any of the
following numbers:
0. Both input and output in direct mode
1. Input in refresh mode, output in direct mode
3. Both input and output in refresh mode Unusable with
An, A3H and
A3M.
D9015
CPU operating
states Operating states of
CPU
• The operation states of CPU as shown below are
stored in D9015.
* When the CPU is in RUN mode and M9040 is off, the
CPU remains in RUN mode if changed to PAUSE
mode.
Usable with all
types of CPUs.
