A199 All 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:
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.
