*7 The relation of dw (Total number of words) and p4 (RX/RY/RWr/RWw data transfer time) is as follows. (Station-based block data
assurance: When "not assured")
When used as a master station
The calculated result (s) is stored in 'Communication cycle interval (calculation value)' (SW0072), 'Cyclic
transmission time (calculation value)' (SW0073), and 'Transient transmission time (calculation value)'
(SW0078).
The calculated result (s) is compared with "Communication Period Interval Setting", "Cyclic Transmission
Time", and "Transient Transmission Time" set in "Communication Period Setting" under "Basic Settings". If
any of them are lower than the calculated result (s), an error occurs. In this case, change the setting values
that have caused the error to a value that is higher than the value shown in the detailed information of module
diagnostics. The following error codes may occur.
• 3010H: The calculated communication cycle interval is higher than the communication cycle interval set in
the engineering tool.
• 3011H: The calculated cyclic transmission time is higher than the cyclic transmission time set in the
engineering tool.
• 3013H: The calculated transient transmission time is higher than the transient transmission time set in the
engineering tool.
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 cycle 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
able to be performed. In such a case, select the actual device to be used from "Module List" to add to the list
of stations, or refer to the manual for the device used to check the maximum response time for the time
managed polling method and calculate and set the communication cycle interval and cyclic transmission time.
