Function
ON when an error has occurred in a Basic I/O Unit
(including C200H Group-2 High-density I/O Units and
C200H Interrupt Input Units).
1: Error
0: No error
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash. The location of the error will be written to A408.
(This flag will be turned OFF when the error is
cleared.)
ON when the Detect Interrupt Task Errors setting in
the PLC Setup is set to "Detect" and an interrupt task
is executed for more than 10 ms during I/O refreshing
of a C200H Special I/O Unit or a SYSMAC BUS I/O
Unit.
This flag will also be turned ON if an attempt is made
to refresh a Special I/O Unit's I/O from an interrupt
task with IORF(097) while the Unit's I/O is being
refreshed by cyclic I/O refreshing (duplicate refresh-
ing).
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash.
1: Error
0: No error
(This flag will be turned OFF when the error is
cleared.)
ON when a non-fatal error is generated by executing
FAL(006). The CPU Unit will continue operating and
the ERR/ALM indicator on the front of the CPU Unit
will flash.
The bit in A360 to A391 that corresponds to the FAL
number specified in FALS(006) will be turned ON and
the corresponding error code will be written to A400.
Error codes 4101 to 42FF correspond to FAL numbers
001 to 2FF (0 to 511).
1: FALS(006) error occurred
0: FALS(006) not executed
(This flag will be turned OFF when the error is
cleared.)
