Turns on when a self-diagnostic error occurs.
⇒ The content of self-diagnostic error is stored in DT90000.

Turns on for an instant when a backup battery error occurs.
Turns on and keeps the on state when a backup
battery error occurs. Once a battery error has been
detected, this is held even after recovery has been
made. It goes off if the power supply is turned off, or if
the system is initialized.
Turns on and keeps the on state shen an operation error
occurs.
⇒The address where the error occurred is stored in DT9017.
(Indicates the first operation error which occurred).
Turns on for an instant when an operation error occurs.
⇒The address where the operation error occurred is stored
in DT9018. The contents change each time a new error
occurs.
This is set if an overflow or underflow occurs in the
calculation results, and as a result of a shift system
instruction being executed.
Turns on for an instant when the compared results become
larger in the comparison instructions.
Turns on for an instant,
when the compared results are equal in the comparison
-
instructions.
when the calculated results become 0 in the arithmetic
-
instructions.
Turns on for an instant when the compared results become
smaller in the comparison instructions.
Turns on when the set time elapses (set value reaches 0) in
the timing operation of the F137(STMR)/F183(DSTM)
auxiliary timer instruction.
The flag turns off when the trigger for auxiliary timer
instruction turns off.
Turns on when a communication error at Tool port has
occurred.
Turns on when the scan time exceeds the time specified in
system register 34 during constant scan execution.
This goes on if 0 has been set using system register 34.
