This error occurs when the cycle time PV exceeds the maximum
cycle time set in the PLC Setup. Review the program to decrease
the cycle time or change the maximum cycle time set in the PLC
Setup.
Refer to the Maximum Interrupt Task Processing Time (A440)
and study the maximum cycle time.
The cycle time can be decreased using the following methods.
• Separate instructions not being executed into different tasks.
• Consider using jump instructions for areas in the task that are
not executed.
• Prohibit cycle refreshing with Special I/O Units that do not
require exchange of cycle data.

FALS instruction
executed (FALS
number 001)
A FALS instruction was executed in the program to
create a fatal error.
C100 hex will be added to the FALS number (001 to
1FF hex) and the result will be stored in A400 as
error codes C101 to C2FF hex.
Check the conditions for executing FALS instruc-
tions and remove any causes for the user-defined
error.
