When the D LINK LED is flashing in green
Check the following items in order from the top.
Item
Is the target NZ2FT-GN set as the reserved station in the master
station setting?
Has the high-priority time synchronization source station been
connected to the network?
When the D LINK LED turns off
Check the following items in order from the top.
Item
Has the Ethernet cable been disconnected?
Does the Ethernet cable meet the standard?
Does the station-to-station distance exceed the range of the
specifications?
Does the cabling condition (bending radius) of the Ethernet cable
exceed the range of the specifications?
Is the hub and other stations turned on?
Is the hub being used corresponds to the specifications of the
master station?
Is the master station connected on the network and operating
normally?
When connecting the line, is a remote station whose power is off
connected between the master station and NZ2FT-GN?
Is a station with a communication error connected between the
master station and NZ2FT-GN?
Or has an error occurred at the master station?
Is the master station and NZ2FT-GN linked up at the expected
communication speed?
Is the IP address of NZ2FT-GN duplicated with other devices
within the access range of CC-Link IE TSN?
Is the station type set to anything other than remote station in the
network configuration setting of the master station?
Does the model name of the remote station match the model
name of the actual machine in the network configuration setting of
the master station?
Has an error occurred in the NZ2FT-GN?
When the ERR. LED turns on or is flashing in red
Check the following item.
Item
Has an error occurred in the NZ2FT-GN?
When the following LEDs turn on in red
• Power supply LED
• Input power supply LED 3.2
• Output power supply LED 4.2
Check the following item.
Item
Is the voltage of the external power supply (24VDC) within the
specified range?
Action
In the network configuration setting of the master station, set "No Setting" for "Reserved/
Error Invalid Station".
The time synchronization source is switched and thus temporarily disconnected. Wait until
communication resumes.
Action
Replace the Ethernet cable.
Replace the Ethernet cables that meet the standards.
Set the station-to-station distance within the range of the specifications.
Set the bending radius of the Ethernet cable to be within the range of the specifications.
Turn on the hub and other stations.
• Use a hub that meets the standard.
• Turn off and on the hub.
• Connect the master station to the network.
• If an error occurs at the master station, eliminate the error at the master station.
The remote station whose power is off will be disconnected. In line topology, the stations
after the disconnected station will be disconnected, so turn on the power.
Eliminate the error at the station with a communication error.
Change the communication speed of the station or hub so that it meets the expected
communication speed.
Change the IP address so that the IP address does not overlap in the access range of
CC-Link IE TSN.
Set the station type to remote station in the network configuration setting of the master
station.
Match the model name of the remote station with the model name of the actual machine
in the CC-Link IE TSN configuration setting of the master station.
Check the details of the error and resolve it.
Action
Identify the cause of the error from the CC-Link IE TSN/CC-Link IE Field diagnostics and
take corrective action.
Action
The power supply voltage is less than 18VDC. Set the voltage value within the range of
performance specifications.
If the problem still persists, replace the NZ2FT-GN.
