Check item
When "Communication Speed" of the master station is 1Gbps, has the cyclic
data size exceeded 2K bytes in total for all slave stations on the CC-Link IE
TSN Class B device side with the communication speed 100Mbps at the
boundary between CC-Link IE TSN Class B (except for the master station)
and CC-Link IE TSN Class A?
Has the cyclic data size exceeded 2K bytes in total for all slave stations on the
CC-Link IE TSN Class A device side at the boundary between CC-Link IE
TSN Class B devices (except for the master station) and CC-Link IE TSN
Class A devices?
In multicast mode, is the CC-Link IE TSN Class A remote station connected to
a local station or remote station that does not support the multicast filter?
■For firmware version "14"
Is a CC-Link IE TSN Class A device that supports the CANopen profile with
the protocol version 2.0 connected?
If the above actions do not solve the problem, perform the following test to check for an error.
• Module communication test ( Page 168 Module Communication Test)
■If the RJ71GN11-T2 with a firmware version of "13" or earlier is used
If the RJ71GN11-T2 with a firmware version of "13" or earlier is used, also check the following items.
Check item
In multicast mode, is the CC-Link IE TSN Class A remote station
connected to the master station?
■If the RJ71GN11-T2 with a firmware version of "11" or earlier is used
If the RJ71GN11-T2 with a firmware version of "11" or earlier is used, also check the following items.
Check item
When "Communication Period Setting" of the master station is set to
"1Gbps" and a CC-Link IE TSN Class B/A device with a communication
speed of 100Mbps is used, does the station repeat disconnection and
return even if "Communication Period Setting" is set to "Low-Speed"?
Action
• Restrict the number of the connected stations so that the cyclic data size of
the devices with communication speed of 100Mbps does not exceed 2K
bytes in total.
• Connect the device with communication speed of 100Mbps to the master
station.
• Correct the number of the connected stations so that the cyclic data size of
the CC-Link IE TSN Class A devices does not exceed 2K bytes in total.
• Connect the CC-Link IE TSN Class A device to the master station.
• Connect the local station or remote station supporting the multicast filter to
the CC-Link IE TSN Class A remote station.
• Set unicast mode.
Update the firmware version of the master station to "15" or later.
Action
• Connect the local station or remote station supporting the multicast filter to the
CC-Link IE TSN Class A remote station.
• Set unicast mode.
Action
Take either of the following actions for wiring and setting.
• Use either P1 or P2 of the master station.
• Connect the data link faulty station to a multicast filter supported device and
activate the multicast mode. ( Manual of the device used)
