Function
ON when index and data registers
are shared between all tasks.
OFF when separate index and data
registers are being used in each
task.
Indicates whether the CPU Unit is
operating in BCD mode or binary
mode.
When an error has occurred, the
error code, error contents, and
error's time and date are stored in
the Error Log Area. Information on
the 20 most recent errors can be
stored.
Each error record occupies 5 words;
the function of these 5 words is as
follows:
1) Error code (bits 0 to 15)
2) Error contents (bits 0 to 15)
3) Minutes (bits 8 to 15),
Seconds (bits 0 to 7)
4) Day of month (bits 8 to 15),
Hours (bits 0 to 7)
5) Year (bits 8 to 15),
Month (bits 0 to 7)
Errors generated by FAL(006) and
FALS(007) will also be stored in this
Error Log.
The Error Log Area can be reset
from the CX-Programmer.
If the Error Log Area is full (20
records) and another error occurs,
the oldest record in A100 to A104 will
be cleared, the other 19 records are
shifted down, and the new record is
stored in A195 to A199.
ON for one cycle after PLC operation
begins (after the mode is switched
from PROGRAM to RUN or MONI-
TOR, for example).
ON for one cycle when step execu-
tion is started with STEP(008). This
flag can be used for initialization pro-
cessing at the beginning of a step.
When a task switches from WAIT or
INI to RUN status, this flag will be
turned ON within the task for one
cycle only.
The only difference between this flag
and A200.15 is that this flag also
turns ON when the task switches
from WAIT to RUN status.
ON when a task is executed for the
first time. This flag can be used to
check whether the current task is
being executed for the first time so
that initialization processing can be
performed if necessary.
