■When the calculation value is larger than the set value
If each calculation result is larger than the set value of "Basic Period Setting" under "Basic Settings" as follows, an error
occurs.
When an error occurs, each calculation value is displayed in "Detailed information" in the [Error Information] tab of module
diagnostics. Correct each set value of "Basic Period Setting" referring to the calculation value displayed so that the set value
is equal to or larger than the calculation value.
• 3010H: When the communication cycle interval (calculation value) [s] is larger than the set value of "Communication
Period Interval Setting"
• 3011H: When the cyclic transmission time (calculation value) [s] is larger than the set value of "Cyclic Transmission Time"
• 3013H: When the transient transmission time (calculation value) [s] is larger than the displayed value of "Transient
Transmission Time"
■When a general CC-Link IE TSN module is CC-Link IE TSN Class A
When "CC-Link IE TSN Class Setting" of the general CC-Link IE TSN module added to the list of stations in "Network
Configuration Settings" is set to CC-Link IE TSN Class A and 'Communication period interval (calculation value)' (SW0072)
and 'Cyclic transmission time (calculation value)' (SW0073) are set to "Communication Period Interval Setting" and "Cyclic
Transmission Time", the cyclic transmission may not be performed. In such a case, perform either of the following operation.
• Select the device to be actually used from "Module List" and add the device to the list of station.
• Check the maximum response time for the time-managed polling by referring to the manual of device to be used, and
calculate and set the values of the communication cycle interval and cyclic transmission time.
Unicast mode (1 Gbps)
■Calculation formula
The processing time for standard stations [ns]=
less than 1 s.
Cyclic transmission time [ns] = 
•  : This value varies depending on whether a CC-Link IE TSN Class A device station with the basic period or normal speed
c
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] is calculated by p1 + p4. Round up values that are less than 1 s.
