As an emergency measure when an error occurs, all outputs from Output
Units can be turned OFF by turning ON the Output OFF Bit (A50015). The
operating mode will remain in RUN or MONITOR mode, but all outputs will be
turned OFF.
Note Normally (when IOM Hold Bit = OFF), all outputs from Output Units are turned
OFF when the operating mode is changed from RUN/MONITOR mode to
PROGRAM mode. The Output OFF Bit can be used to turn OFF all outputs
without switching to PROGRAM mode and stopping program execution.
The FAL(006) and FALS(007) instructions generate user-defined errors.
FAL(006) generates a non-fatal error and FALS(007) generates a fatal error
that stops program execution.
When the user-defined error conditions (execution conditions for FAL(006) or
FAL(007)) are met, the Failure Alarm instruction will be executed and the fol-
lowing processing will be performed.
1. The FAL Error Flag (A40215) or FALS Error Flag (A40106) is turned ON.
2. The corresponding error code is written to A400.
3. The error code and time of occurrence are stored in the Error Log.
4. The error indicator on the front of the CPU Unit will flash or light.
5. If FAL(006) has been executed, the CPU Unit will continue operating.
If FALS(007) has been executed, the CPU Unit will stop operating. (Pro-
gram execution will stop.)
Operation of FAL(006)
When execution condition A goes ON, an error with FAL number 2 is gener-
ated, A40215 (FAL Error Flag) is turned ON, and A36002 (FAL Number 2
Flag) is turned ON. Program execution continues.
Errors generated by FAL(006) can be cleared by executing FAL(006) with
FAL number 00 or performing the error read/clear operation from a Program-
ming Device (including a Programming Console).
Operation of FALS(007)
When execution condition B goes ON, an error with FALS number 3 is gener-
ated, and A40106 (FALS Error Flag) is turned ON. Program execution is
stopped.
Errors generated by FAL(006) can be cleared by eliminating the cause of the
error and performing the error read/clear operation from a Programming
Device (including a Programming Console).
