If the above actions do not solve the problem, perform the module communication test to check for hardware failure. (
Page 168 Module Communication Test)
When "Connection
Device Information"
under "Basic Settings"
of the master station is
set to "Mixture of CC-
Link IE TSN Class B/A
or CC-Link IE TSN
Class A Only"
■
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?
Update the firmware version of the master station to "15" or later.
If the stations are connected in a line topology, do "Communication Speed" for
the stations match one another?
Correct "Communication Speed" under "Application Settings" for the stations
so that the communication speeds match one another.
Is there any reason why cyclic transmission cannot be performed on the slave
station side?
• Check if an error has occurred on the slave station.
• Check if the slave station settings and parameters are correct.
• Refer to the manual of the slave station for troubleshooting.
Is the event code 00C44 registered in the event history?
Match the communication speed of the master station to the communication
speed of the station for which the slave station parameter automatic setting is
to be configured.
When "Network
Topology" under "Basic
Settings" of the master
station is set to "Ring"
Is a switching hub used?
Disconnect the switching hub.
Is a device not supporting ring topology
connected?
Disconnect the device not supporting ring topology, and connect a device
supporting ring topology.
Is the communication speed of the master station
the same as the communication speed of slave
station?
Ensure that the communication speed of the master station and the
communication speed of slave station match.
■
For firmware version "13" or earlier
Is a device not set in "Network Configuration
Settings" of the master station connected?
Disconnect the device not set in "Network Configuration Settings" of the
master station.
Is the minimum value for communication cycle interval set to both
"Communication Period Interval Setting" and "Cyclic Transmission Time" in
"Communication Period Setting" under "Basic Settings" of the module
parameter?
Set "Cyclic Transmission Time" to a value obtained by the following formula:
Minimum value of cyclic transmission time + Greatest value among the two
values shown below.
• 10% of the calculated minimum cyclic transmission time
• When the communication speed of the master station is set to 1Gbps:
Number of slave stations
2
s
• When the communication speed of the master station is set to 100Mbps:
Number of slave stations
20
s
Is the minimum value for cyclic transmission time set to "Cyclic Transmission
Time" in "Communication Period Setting" under "Basic Settings" of the module
parameter?
In multicast mode, has an external device sent a frame to a station before data
link establishment of all stations?
Ensure that the external device will not send a frame before data link
establishment of all stations, then reset the master station.
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?
• 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.
■
For firmware version "14"
When the communication speed of the master station and the slave station of
the CC-Link IE TSN Class A is 1Gbps, is the "Communication Period Setting"
of the slave station of the CC-Link IE TSN Class A set to "Basic Period" or
"Normal-Speed"?
• Update the firmware version of the master station to "15" or later.
• Set the value set for "Communication Period Interval Setting" and "Cyclic
Transmission Time" in "Communication Period Setting" under "Basic
Settings" to greater than or equal to the calculation value of the calculation
formula. (
