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?
Safety communications failed
The following lists the actions to be taken if safety communications cannot be performed.
Check item
Is a safety station specified as a reserved station in "Network
Configuration Settings" of "Basic Settings" of the master station?
Is safety connection set among safety stations that perform safety
communications?
Is the setting value of "Sending Interval Monitoring Time" in "Safety
Communication Setting" under "Basic Settings" correct?
Is the setting value of "Safety Refresh Monitoring Time" in "Safety
Communication Setting" under "Basic Settings" correct?
Does safety station interlock status indicate interlock state?
Is a standard station set for the IP address of the communication
destination in "Safety Communication Setting" under "Basic Settings" in
the local station?
Is "Safety Data Transfer Device Setting" in "Safety Communication
Setting" under "Basic Settings" correctly set?
When safety communications are performed with the remote station
(safety station), has the safety module validation been performed?
Is the setting for the CPU number when the CPU module to be selected
the CPU number in the communication destination is selected in "Safety
Communication Setting" of "Basic Settings" of the master station
correctly set?
If the above actions do not solve the problem, perform the module communication test to check for hardware failure. (
Page 168 Module Communication Test)
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
Set "No Setting" for "Reserved/Error Invalid Station" in "Network Configuration
Settings" under "Basic Settings" of the master station. ( Page 117 "CC-Link IE
TSN Configuration" Window)
Set safety connection among safety stations that perform safety communications in
"Safety Communication Setting" under "Basic Settings".
Correct the setting value of "Sending Interval Monitoring Time" in "Safety
Communication Setting" under "Basic Settings". ( Page 315 Transmission
interval monitoring time)
Correct the setting value of "Safety Refresh Monitoring Time" in "Safety
Communication Setting" under "Basic Settings". ( Page 316 Safety refresh
monitoring time)
• Correct the setting value of "Sending Interval Monitoring Time" in "Safety
Communication Setting" under "Basic Settings". ( Page 315 Transmission
interval monitoring time)
• Correct the setting value of "Safety Refresh Monitoring Time" in "Safety
Communication Setting" under "Basic Settings". ( Page 316 Safety refresh
monitoring time)
• Release the interlock state by using Interlock release request for each safety
connection. ( MELSEC iQ-R CPU Module User's Manual (Application))
Set a safety station for the IP address of the communication destination in "Safety
Communication Setting" under "Basic Settings".
Correct "Safety Data Transfer Device Setting" set in "Safety Communication
Setting" under "Basic Settings" among safety stations that perform safety
communications.
Perform the safety module validation. ( Manual for the remote station used)
Set the CPU number of the CPU module in a local station to perform safety
communications with the master station. ( User's manual for the CPU module of
the communication destination)
