Check item
Are the stations linked up between the master station and the
NZ2AW1GNAL at the desired communication speed?
Is the time synchronization source station operating normally?
Is the high-priority time synchronization source station newly
connected to the network?
Does the model name of the slave station set in "Network
Configuration Settings" of "Basic Settings" match the model
name of the actual device?
Has an error occurred on the NZ2AW1GNAL?
Is event code 00C71 registered in the event history of the
master station?
When the P1 LINK LED and P2 LINK LED turn off
When the P1 LINK LED and P2 LINK LED turn off, check the following items.
Check item
Is the Ethernet cable properly attached?
Is an Ethernet cable that meets the standards being used?
Is the station-to-station distance 100m or less?
Is the condition of the laid cabling (bending radius) within the
specifications?
Is the Ethernet cable disconnected?
Are the other stations connected to the NZ2AW1GNAL
operating normally?
Is the switching hub used operating normally?
Is the communication speed of the connected device 1Gbps?
When the ERR. LED turns on or flashes
When the ERR. LED turns on or flashes, check the following items.
Check item
Has an error occurred?
When the SET LED turns on or flashes
When the SET LED turns on or flashes, check the following items.
Check item
Was the power turned off during automatic address detection?
Action
Change the communication speed of the station or switching hub to meet the desired
communication speed.
• If an error has occurred at the time synchronization source station, clear the error.
• If the time synchronization source station is reset or the power is turned off, the line is
temporarily disconnected due to the switching the time synchronization source, so wait
until communication restarts.
The line is temporarily disconnected due to switching the time synchronization source, so
wait until communication restarts.
Change the network configuration settings so that the model name of the slave station set in
"Network Configuration Settings" of "Basic Settings" matches the model name of the actual
device. Alternatively, set the NZ2AW1GNAL as a general-purpose remote station in the
network configuration settings.
Use the engineering tool to check the error content of the NZ2AW1GNAL, and clear the
error.
If the CC-Link IE TSN network synchronous communication function is enabled for the
NZ2AW1GNAL, disable the CC-Link IE TSN network synchronous communication function.
If event code 00C71 is still registered after taking the above action, check the manual of the
master station and clear the cause of event code 00C71.
Action
If the Ethernet cable is not properly attached, attach it properly. ( Page 30 CC-Link IE
TSN Connector Wiring)
Replace the cable with an Ethernet cable that meets the standards. ( User's manual for
the master station used)
Change the station-to-station distance to 100m or less.
Refer to the manual for the Ethernet cable, and correct the bending radius to within the
specification.
Replace the Ethernet cable.
Check that the systems on other stations are powered on.
• Check that the switching hub is powered on.
• Check that the switching hub being used supports the specifications of the master station
used. ( User's manual for the master station used)
• After disconnecting the Ethernet cable, attach the Ethernet cable again.
• Power off and on the switching hub.
Connect a device that supports a communication speed of 1Gbps.
Action
Use the engineering tool to check the error content of the NZ2AW1GNAL, and take
corrective action. ( Page 117 How to Check Error Codes and Alarm Codes)
Action
Execute automatic address detection again.
