10 TROUBLESHOOTING
10.4 Troubleshooting by Symptom
If the above actions do not solve the problem, perform the module communication test to check for hardware failure. (
Page 200 Module communication test)
The connection device
information 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 devices supporting the CC-Link IE TSN
Protocol version 2.0
Do the system configuration of mixture of CC-Link IE
TSN Class B/A and "TSN HUB Setting" in
"Connection Device Information" under "Basic
Settings" differ?
For details, refer to the following.
Page 220 A CC-Link IE TSN Class A device does not perform data
link.
For devices supporting the CC-Link IE TSN
Protocol version 2.0
If the "CC-Link IE TSN Class" of the general CC-Link
IE TSN module added to the list of stations under the
network configuration settings is CC-Link IE TSN
Class A, is the minimum value of the communication
cycle interval ([Basic Settings] of the module
parameter [Communication Period Setting]
[Basic Period Setting]) set to "Communication Period
Interval Setting" and "Cyclic Transmission Time"?
Select the actual device to be used from "Module List" of the network
configuration setting and add it to the list of stations, or check the
maximum response time during time-managed polling using the manuals
of the devices, and set the calculated values for the communication cycle
interval and cyclic transmission time.
Is the event code 00C72 registered in the event
history of the master station?
• Update the engineering tool to the latest version.
Take the following action for the device station with the IP address
displayed in the detailed information of the event history.
• Update the firmware of the device stations to the latest version.
For firmware version "1.010" or earlier
Is a CC-Link IE TSN Class A device that supports the
CANopen profile with the CC-Link IE TSN Protocol
version 2.0 connected?
Update the firmware version of the master station to "1.020" or later.
When the station is connected in line topology, is the communication speed setting
matched among stations?
Correct "Communication Speed" under "Application Settings" so that the
communication speed is matched for each station.
Is there any reason on the device station side why cyclic communication is not
performed?
• Check if an error has occurred on the device station.
• Check if the device station settings and parameters are correct.
• Refer to the manual of the device station for troubleshooting.
Is the event code 00C44 registered in the event history? Set the same communication speed for the master station and the device
station parameter automatic setting target station.
Is the minimum value for the communication cycle interval ([Basic Settings] of the
module parameter [Communication Period Setting] [Basic Period Setting]) set
to "Communication Period Interval Setting" and "Cyclic Transmission Time"?
Set "Cyclic Transmission Time" to a value obtained by the following
formula: Minimum value of cyclic transmission time + Greatest value
among the three values shown below.
• 10% of the minimum value of the calculated cyclic transmission time
• When the communication speed of the master station is set to 1Gbps:
Number of device stations 2s
• When the communication speed of the master station is set to
100Mbps: Number of device stations 20s
Is a device number outside the setting range set for a link side device in "Refresh
Setting"?
Check that the device numbers of RX and RWr set in "Refresh Setting"
are within the applicable range.
In multicast mode, has an external device sent a frame 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, does the cyclic data
size exceed 2K bytes in total for all device stations on the 100Mbps device side at
the boundary between a 1Gbps CC-Link IE TSN Class B device except for the
master station and 100Mbps CC-Link IE TSN Class B device?
• Restrict the number of connected stations so that the cyclic data size
of 100Mbps devices does not exceed 2K bytes in total.
• Connect 100Mbps device to the master station.
For firmware version "1.002" or earlier
When the communication speed of the master station and CC-Link IE TSN Class A
device station each are 1Gbps, is "Communication Period Setting" of the CC-Link
IE TSN Class A device station set to "Basic Period" or "Normal Speed"?
•
Update the firmware version of the master station to "1.010" or later.
• For the values set for "Communication Period Interval Setting" and
"Cyclic Transmission Time" each in "Communication Period Setting"
under "Basic Settings", set a value not smaller than the minimum value
for the communication cycle interval (cyclic data transfer processing
time).
