1. OVERVIEW OF A-MOTION REPLACEMENT
6.3 Precautions of Program Transition
6.3.1 Precautions of shared device memory transition between SCPU (PLC) and PCPU (Motion
CPU)
PLC CPU and Motion CPU are integrated in A-Motion, while these are not integrated in QDS-Motion.
And the shared device memory can be used by the Multiple CPU high speed transmission (+ automatic
refresh). Therefore it is necessary to execute the automatic refresh setting and allocate to the Motion CPU
device which used PLC CPU after the project diversion. Pay attention to the number of automatic refresh
block because the limit is 32 in Q173DSCPU/Q172DSCPU.
[Advantage]
- 0.88ms cyclical transition can be done in high speed transmission area
QBus
- Automatic refresh per operation cycle is possible
