6-17 Task Flags

Task Flags range from TK0 to TK127 and correspond to cyclic tasks 0 to 127.
A Task Flag will be ON when the corresponding cyclic task is in READY or RUN status and OFF when
the cyclic task is in INI or WAIT status.
Note These flags indicate the status of cyclic tasks only, they do not reflect the status of extra cyclic
tasks or interrupt tasks.
The Task Flags will be cleared in the following cases, regardless of the status of the IOM Hold Bit
(A500.12).
• The operating mode is changed from PROGRAM mode to RUN/MONITOR mode or vice-versa.
• The PLC's power supply is cycled.
The Task Flags cannot be force-set or force-reset.
