■ Calculation formula
Communication cycle interval [ns] = 
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.
Item
When a CC-Link IE TSN Class A device station with the basic cycle or normal
speed cycle does not exist
When a CC-Link IE TSN Class A device station with the basic cycle or normal

5 The largest value among the maximum response times during the time-managed polling of the CC-Link IE TSN Class A device stations set in the basic
cycle or medium speed cycle
*1 The symbols in the table are as follows.
A1, B1, C1: Main module calculation formula
A2, B2, C2: Extension module calculation formula
For the maximum response time for time-managed polling for the device stations, refer to the user's manual
for the device station used.
•  : The calculation formula is as follows.

{(42  (sn1r+sn1l)) + (16  (sn2r+sn2l)) + (sndmr+sndml)}  80
Cyclic processing time [ns] = 
