Error Log Area
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:
First word: Error code (bits 0 to 15)
First word + 1: Error contents (bits 0 to
15)
First word + 2: Minutes (upper byte),
Seconds (lower byte)
First word +
3
: Day of month (upper
byte), Hours (lower byte)
First word + 4: Year (upper byte),
Month (lower byte)
Note 1
Errors generated by FAL(006)
and FALS(007) will also be
stored in this Error Log.
2
The Error Log Area can be
reset from the CX-Program-
mer.
3
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.

data will be for 1:01.01 on Sun-

Task Started Flag
When a task switches from WAIT or INI
to RUN status, this flag will be turned
ON within the task for one cycle only.
Note
The only difference between this
flag and A200.15 is that this flag
also turns ON when the task
switches from WAIT to RUN sta-
tus.
ON: ON for first cycle

transitions from
WAIT and IN)

First Task Startup Flag
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.
ON: First execution
OFF: Not executable
or not being
executed for the
first time.
