(2) Configuring sequence control and motion control systems on the same base
unit
In a multiple CPU system consisting of a QCPU and Motion CPU, sequence control and motion control can be
implemented together to achieve a high-level motion system.
Interaction with Motion CPUs for motion control is enhanced in Universal model QCPUs.
(a) High-speed data transfer between CPU modules
In a multiple CPU system, up to 14K-word data are transferred in parallel with programs between CPU
modules. This enables high-speed data transfer independent of scan time, and shortens the takt time of the
entire system. ( Page 150, Section 6.1.3)
