Too Long
Flag
The cycle time has exceeded
the maximum cycle time
(watch cycle time) set in the
PLC Setup.
Change the program to reduce the cycle
time or change the maximum cycle time
setting.
Check the Maximum Interrupt Task Pro-

Cycle Time Watch Time can be
changed.
The cycle time can be reduced by divid-
ing unused parts of the program into
tasks, jumping unused instructions in
tasks, and disabling cyclic refreshing of
Special I/O Units that don’t require fre-
quent refreshing.
