FAL(06) produces a non-fatal error and FAL(07) produces a fatal error. When
FAL(06) is executed with an ON execution condition, the ALARM/ERROR
indicator on the front of the CPU will flash, but PC operation will continue.
When FALS(07) is executed with an ON execution condition, the ALARM/ER-
ROR indicator will light and PC operation will stop.
The system also generates error codes to the FAL area.
A maximum of three FAL error codes will be retained in memory, although
only one of these is available in the FAL area. To access the other FAL
codes, reset the FAL area by executing FAL(06) 00. Each time FAL(06) 00 is
executed, another FAL error will be moved to the FAL area, clearing the one
that is already there.
FAL(06) 00 is also used to clear message programmed with the instruction,
MSG(46).
If the FAL area cannot be cleared, as is generally the case when FALS(07) is
executed, first remove the cause of the error and then clear the FAL area
through the Programming Console (see 4-5-5 Clearing Error Messages).

Limitations
Can be performed with the CPU11-E only. Only the rightmost three digits of
Mi are used.
Description
SCAN(18) is used to set a minimum cycle time. Mi is the minimum cycle time
that will be set in milliseconds, e.g., if Mi is 120, the minimum cycle time will
be 120 ms. The possible setting range is from 0 to 999 seconds.
If the actual cycle time is less than the cycle time set with SCAN(18) the CPU
will wait until the designated time has elapsed before starting the next cycle.
If the actual cycle time is greater than the set time, the set time will be ig-
nored and the program will be executed to completion.
