Cyclic Transmission Time (Minimum value)
Communication Period Interval (Minimum
value)
Description
The cyclic transmission time that are calculated by the number of
device stations and the number of points of link devices, or the
values set for standard communications and safety
communications is displayed. Use the displayed value as a
*1
guide.
Even if the number of device stations and link device points are
the same, the displayed values differ depending on "TSN HUB
Setting" of "Connection Device Information" under "Basic
Settings". For details, refer to the following.
Page 275 Communication cycle interval
The displayed value can be used for "Cyclic Transmission Time"
in "Communication Period Setting" under "Basic Settings" of the
module parameter.
If cyclic transmission is not performed by setting the displayed
value, set a value obtained by adding 10% as follows.
• 10% of the minimum value of the calculated cyclic
transmission time
• When the communication speed for the master station is set to
1 Gbps: The number of device stations  2 s
• When the communication speed for the master station is set to
100 Mbps: The number of device stations  20 s
When the communication speed of the master station is 1Gbps
in unicast mode or multicast mode with version 1.085P or earlier
of the engineering tool (if a CC-Link IE TSN Class A device
station with the basic cycle or normal speed cycle exists), the
time cannot be checked. Check it with 'Cyclic transmission time
(calculation value)' (SW0073).

The communication cycle intervals that are calculated by the
number of device stations and the number of points of link
devices by using the values set for standard communications
and safety communications are displayed. Use the displayed
*1
value as a guide.
Even if the number of device stations and link device points are
the same, the displayed values differ depending on "TSN HUB
Setting" of "Connection Device Information" under "Basic
Settings". For details, refer to the following.
Page 275 Communication cycle interval
The displayed value can be used for "Communication Period
Interval Setting" in "Communication Period Setting" under "Basic
Settings" of the module parameter.
If cyclic transmission is not performed by configuring the setting
with the displayed value, set a value obtained by adding 10% as
follows.
Calculation formula: B + A  0.1
A: Cyclic transmission time (minimum value)
B: Communication cycle interval (minimum value)
When the communication speed of the master station is 1Gbps
in unicast mode or multicast mode with version 1.085P or earlier
of the engineering tool (if a CC-Link IE TSN Class A device
station with the basic cycle or normal speed cycle exists), the
interval cannot be checked. Check it with 'Communication cycle
interval (calculation value)' (SW0072).
