Description
The cyclic transmission time that are calculated by the number of
slave 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.
The displayed value differs depending on "TSN HUB Setting" of
"Connection Device Information" under "Basic Settings" even
when the number of slave stations and link device points are the
same. For details, refer to the following.
Page 293 Communication cycle intervals
The displayed value can be used for "Cyclic Transmission Time"
in "Communication Period Setting" under "Basic Settings" of the
module parameter.
If the cyclic transmission is not performed while the displayed
value is set, set a value obtained by the following formula: Value
displayed in Cyclic Transmission Time (Min.) + Greatest value
among the two values shown below.
• 10% of the minimum value of the calculated cyclic
transmission time
• When the communication speed for the master station is set to
1Gbps: The number of slave stations  2s
• When the communication speed for the master station is set to
100Mbps: The number of slave 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 slave station
with the basic cycle or normal speed cycle exists), the time
cannot be checked. Check it with 'Cyclic transmission time
(calculation value)' (SW0073).
