b. Cyclic task processing
i. Executes the corresponding cyclic task program per setting time interval
(execution cycle)
c. When using cyclic task program
i. When cyclic task program is currently executing or waiting to execute, if the
command to execute the same task program occurs, the new task will be
ignored.
ii. Timer that initiates a command to execute cyclic task program only while in Run
mode, shall be added. The shutdown time shall be all disregarded.
iii. When setting the execution cycle of cyclic task program, consider the conflict of
overlapping. If 4 cyclic task programs of 2sec, 4sec, 10sec, and 20sec are
used, 4 cycles of execution per 20 seconds shall occur at the same time and
scan time may extend instantaneously.
