Precautions
• For details on troubleshooting by symptom, refer to the following.
Page 138 Troubleshooting by Symptom
• The protocol in operation can be found in 'Protocol operating status' (Un\G91270).
• If the device station used is "CC-Link IE TSN Class A" and "Communication Period Setting" is set to "Low-Speed", sending/
receiving cyclic data within the "Low-Speed" period to/from the device station with "Communication Period Setting" set to
"Low-Speed" cannot be guaranteed depending on the setting values for the maximum response time for the time managed
polling method, communication period interval, and low-speed setting. In this case, the error "Communication period setting
error" (error code: 31ABH) occurs and the Motion module stops.
• If "CC-Link IE TSN Class Setting" is "CC-Link IE TSN Class A" and a device station where "Communication Period Setting"
is set to "Low-Speed" exists, parameter values that can guarantee the sending/receiving of cyclic data to/from the device
station whose "Communication Period Setting" is set to "Low-Speed" within the "Low-Speed" period are stored in "Multiple
cycle setting (low speed)" (Un\G91312) and "Communication cycle intervals (calculation value)" (Un\G91313). Set the
"Multiple Period Setting" to "Low-Speed" and "Communication Period Interval Setting" to a value equal to or greater than
the value stored in "Multiple cycle setting (low speed)" (Un\G91312) and "Communication cycle intervals (calculation
value)" (Un\G91313).
• When "CC-Link IE TSN Class Setting" of the general CC-Link IE TSN module added to "Network Configuration Settings" is
set to "CC-Link IE TSN Class A", if "Multiple Period Setting" is set to "Low-Speed" and "Communication Period Interval
Setting" is set to 'Multiple period setting (low speed)' (Un\G91312) and 'Communication cycle interval (calculation value)'
(Un\G91313), the cyclic data may not be sent/received. In this case, add the actual device to be used to "Network
Configuration Settings", 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 setting value.
Operation when versions of connected devices are combined
The following tables show whether restrictions apply to possible combinations of connected devices that support the CC-Link
IE TSN Protocol version 2.0 and those that do not.
• Restrictions: Up to eight CC-Link IE TSN Class B devices can be connected to the master station.

• Restrictions: Connection cannot be made if the total cyclic data size of all device stations on the CC-Link IE TSN Class A
device side that form a boundary between CC-Link IE TSN Class B and CC-Link IE TSN Class A devices exceeds 2K
bytes.
