(g) Group cyclic transmission
Cyclic transmission can be performed only with specified stations.
A Universal model QCPU can share cyclic data with stations in the same shared group. ( Page 83,
Section 4.1.8)
This function is useful, for example, when sharing data among all stations that integrates and controls
production lines and not sharing the data with stations that controls other machines.
Also, receiving cyclic data only from any specific stations can reduce the number of link refresh points, resulting
in a shorter link refresh time.
