Interaction with a motion controller for motion control is enhanced in the Universal model QCPU.
(a) Speeding up data transfer between multiple CPUs
Maximum 14 k word-data and a sequence program can be transferred between multiple CPUs with parallel
processing. It enables high-speed data transfer independent of scan time, which leads to takt time shortening
of equipment.
