QCPU (Q Mode)/QnACPU Programming Manual (Common Instructions)
2) Clearing by GX Developer
Choose [Online] [Clear PLC memory] and execute device memory all clear
(including latch).
POINT
1. When the start mode of the Redundant CPU is the hot-start mode, the data
outside the latch range are also held.
(Except some devices such as the step relay and index register.).
2. For the Universal model QCPU, the scan time is prolonged when the device is
latched. When latching a device, consider the prolonging scan time.
( Section 10.1.2 (11) )
