Calculation formula
Communication cycle interval [ns] =
c
+
p
+
sc
+
sp
. Round up values of
c
,
p
,
sc
, and
sp
that are less than 1
s.
Cyclic transmission time [ns] =
c
+
sc
•
c
: This value varies depending on whether a CC-Link IE TSN Class A slave station with the basic cycle or normal speed
cycle exists or not.
*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 slave stations, refer to the user's manual for
the slave station used.
•
sc
: The calculation formula is as follows.
Cyclic processing time [ns] =
p
+
sp
or 340000, whichever is larger.
•
p
: p1+p2+p3+kp+kum
•
sc
is calculated by p4.
■
Variable
For each variable to be used, round it up to one decimal point before assigning to the calculation formula.

When a CC-Link IE TSN Class A slave station with the basic cycle or normal
speed cycle does not exist
No.1 + No.4
When a CC-Link IE TSN Class A slave station with the basic cycle or normal
speed cycle exists
No.1+No.4+No.5
