Unicast mode (1 Gbps)
■ Calculation formula
The communication cycle interval [ns] is calculated as follows. Round up less than 1 s in 
When using the PLCopen Motion control FB mode: 
When using the Simple Motion mode: 
Cyclic transmission time [ns] = 
•  :This value varies depending on whether a CC-Link IE TSN Class A device station with the basic cycle or normal speed
c
cycle exists or not.
