Master station
The transmission delay time is the total of (1) to (7).
No. Description
(1) CC-Link IE TSN master station sequence scan time
(2) CC-Link IE TSN master station link refresh time
(3) CC-Link IE TSN cyclic data transfer processing time
(communication cycle interval)
(4) NZ2GN-GFB device transfer time
(5) CC-Link IE Field Network link scan time
(6) CC-Link IE Field Network local station link refresh time
(7) CC-Link IE Field Network local station sequence scan time
For details on calculating (1) + (2) + (3), refer to the user's manual for the CC-Link IE TSN master station
used.
The following shows the variables used to calculate the transmission delay time.
Variable Description
Tb NZ2GN-GFB device transfer time
LS_field CC-Link IE Field Network link scan time
SL_field CC-Link IE Field Network local station sequence scan time (including link refresh time)
(LS_field  m_field)  SL_field (round up the calculated value to the nearest integer)
n_field
(SL_field  LS_field) (round up the calculated value to the nearest integer)
n3_field
(SL_field  (LS_field  m_field)) (round up the calculated value to the nearest integer)
k_field
m_field Constant value based on the number of RWw assignment points of CC-Link IE Field Network local stations
