(4) Latch interval setting
Data are latched at each scan or at set intervals. Latch timing is set in
(a) Each scan
Latch data processing is performed during END processing of each scan. Since device data is latched every
scan, the CPU module holds the latest device data at all times.
(b) Time setting
Latch data processing starts during the first END processing after a preset time has elapsed. Since the latch
data processing is performed asynchronous to the sequence program, an increase in scan time is reduced.
If the latch interval is shorter than a scan time, the latch timing occurs more than once within one scan. However, the latch
processing is performed only once during the END processing.
Note 3.1
Universal
Only the High-speed Universal model QCPU can select "Time Setting" in parameter. The latch interval setting is fixed to
"Each Scan" for other CPU modules.
