executed (FAL
number 001)
The executed FAL number 001 to 511 will be stored
in A360 to A391. The number 4 will be added to the
front of 101 to 2FF (which correspond to executed
FAL numbers 001 to 511) and the result will be
stored in A400 as error code 4101 to 42FF.
Check the conditions for executing FAL instructions
and remove any causes of the user-defined error.

An interrupt task error occurs when the
Detect Interrupt task errors set-
ting
in the PLC Setup is set to
Detect
and an attempt is made to refresh a
Special I/O Unit from an interrupt task with IORF(097) while the Unit’s I/O
is being refreshed by cyclic refreshing (duplicate refreshing).
Review the program to see whether detecting interrupt task errors can be
disabled or avoided.
