Desynchronization with CC-Link IE TSN network synchronous communication function
When synchronization cannot be performed with the CC-Link IE TSN network synchronous communication function, check
the following items.
Check item
Is an inter-module synchronization target module selected?
Is an inter-module synchronous master set?
Is the network synchronous communication of the slave station set in the
network configuration settings of the master station?
Is the network synchronous communication set in the parameter settings of
the slave station?
Does the firmware version of the CPU module support the CC-Link IE TSN
network synchronous communication function?
Cannot be monitored using the CC-Link IE TSN Communication Software
The following lists the actions to be taken if information cannot be monitored using the CC-Link IE TSN Communication
Software.
Check item
Are three or more modules connected to CC-Link IE TSN Communication
Software?
Is the CC-Link IE TSN Communication Software connected to a CC-Link IE
TSN Class A device?
Is "Communication Mode" under "Application Settings" set to "Unicast"?
Is the CC-Link IE TSN Communication Software connected to a general-
purpose hub?
Does the CC-Link IE TSN Communication Software reconnect within 20
seconds of disconnecting?
In addition to the above actions, refer to the following troubleshooting methods.
 CC-Link IE TSN Communication Software for Windows User's Manual
Data is not displayed correctly in the "CC-Link IE TSN/CC-Link IE Field Diagnostics"
If data is not displayed correctly in the network map or selected station communications status monitor of the "CC-Link IE
TSN/CC-Link IE Field Diagnostics" window, check the following items.
Check item
Is the network in the ring topology configured correctly?
Action
Set "Select Inter-module Synchronization Target Module" under "Inter-module
Synchronization Setting" in the "System Parameter" window to "Synchronous".
For "Synchronization Master Setting of CC IE TSN/CC IE Field" in "Inter-module
Synchronization Master Setting" of "Inter-Module Synchronization Setting" in
"System Parameter", set "Mounting Slot No." for the inter-module synchronous
master.
For details on the inter-module synchronous master, refer to the following.
 MELSEC iQ-R Inter-Module Synchronization Function Reference Manual
By using "Network Configuration Settings" under "Basic Settings" of the module
parameter, set "Network Synchronous Communication" of the slave station to
"Synchronous".
Set "Network Synchronous Communication" in the parameter settings of the
slave station to "Synchronous". ( Manual for the module used)
Check the firmware version of the CPU module in "Product Information List" of
"System Monitor". If the firmware version of the CPU module does not support
the CC-Link IE TSN network synchronous communication function, either update
the firmware of the CPU module or change the CPU module to a CPU module
supporting that function.
Action
Connect two or fewer modules.
Connect the CC-Link IE TSN Communication Software to a CC-Link IE TSN
Class B device or a TSN hub.
Set "Communication Mode" under "Application Settings" to "Multicast".
Connect the CC-Link IE TSN Communication Software to a CC-Link IE TSN
Class B device or a TSN hub.
Before reconnecting the CC-Link IE TSN Communication Software, wait more
than 20 seconds.
Action
Correct the wiring so that the connection becomes different from the connection
in "Network Topology" under "Basic Settings" of the master station.
