Multicast mode (100Mbps)
Calculation formula
Communication cycle interval [ns] = 
c
+ 
p
. Round up values of 
c
and 
p
that are less than 1s.
Cyclic transmission time [ns] = 
c
• 
c
: This value varies depending on whether a CC-Link IE TSN Class A device station with the basic period or normal speed
period exists or not.
For details on the maximum response time for the time managed polling method of a device station, refer to
the user's manual for the device station used.
Cyclic processing time [ns] = 
p
or 340000, whichever is larger. Round up values that are less than 1s.
• 
p
: Cyclic processing time [ns] is calculated by p1 + p4. Round up values that are less than 1s.
Variable
For each variable (excluding Mg) to be used, round it up to one decimal point before assigning to the calculation formula.
The parts enclosed in double quotation marks (" ") in the description are the setting values for "Network Configuration
Settings".
Item Calculation formula
When a CC-Link IE TSN Class A device station with the basic period or
normal speed period does not exist
(The value in No.1 or No.4, whichever is larger) + No.5
When a CC-Link IE TSN Class A device station with the basic period or
normal speed period exists
(The value in No.1 or No.4, whichever is larger) + No.5 + No.6
Calculation formula
No.1 A1 + A2 + (No.3 or
No.4, whichever is
larger)
