Multicast mode (1Gbps)
■ Calculation formula
The communication cycle interval [ns] is as follows. Round up values of α
When using Motion control FB mode: The larger value of α
When using Simple Motion mode: The larger value of α
Cyclic transmission time [ns] = α
• αc: This value varies depending on whether a CC-Link IE TSN Class A device station with the basic cycle or normal speed
cycle exists or not.
