Synchronization cannot be performed with the CC-Link IE TSN Network synchronous
communication function
When the 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 set to the standard device station
in the network configuration setting of the master station?
Is the network synchronous communication set in the parameter settings of
the device 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?
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 "Fixed Scan Interval Setting of
Inter-module Synchronization" 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
Set "Network Synchronous Communication" to "Synchronous" for the
standard device station under "Network Configuration Settings" in the module
parameters.
Set "Network Synchronous Communication" in the parameter settings of the
device 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, 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 112 "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 296 Transmission
interval monitoring time)
Correct the setting value of "Safety Refresh Monitoring Time" in "Safety
Communication Setting" under "Basic Settings". (Page 296 Safety refresh
monitoring time)
• Correct the setting value of "Sending Interval Monitoring Time" in "Safety
Communication Setting" under "Basic Settings". (Page 296
Transmission interval monitoring time)
• Correct the setting value of "Safety Refresh Monitoring Time" in "Safety
Communication Setting" under "Basic Settings". (Page 296 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)
