2. REPLACEMENT PROPOSAL FROM A-MOTION TO QDS-MOTION
(2) Obtain synchrony between SCPU and PCPU
Since QDS-Motion has a PLC CPU and a Motion CPU as different modules, the task processing
time differs. To synchronize the start timing of task processing, configure some settings
(assignment to multiple CPU shared device/automatic refresh setting) for the task start trigger
(device).
For details of (1) and (2), refer to "QCPU User's Manual (Multiple CPU System) Model code:
SH-080485ENG" and "Programming Manual (COMMON) [type Q173D(S)/Q172D(S)] Model
Code: 1XB928", and set common devices.

By sharing the task start trigger (device)
(assignment to multiple CPU shared device/
