Check item
Action
Is an Ethernet cable that meets the standards being used?
Replace the cable with an Ethernet cable that meets the standards. (
User's manual for
the master station used)
Is the station-to-station distance 100m or less?
Change the station-to-station distance to 100m or less.
Is the condition of the laid cabling (bending radius) within the
specifications?
Refer to the manual for the Ethernet cable, and correct the bending radius to within the
specification.
Is the Ethernet cable disconnected?
Replace the Ethernet cable.
Is the Ethernet cable properly attached?
If the Ethernet cable is not properly attached, attach it properly. (
Are the other stations connected to the NZ2AW1GNAL
operating normally?
Check that the systems on other stations are powered on.
Is the switching hub used operating normally?
• 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.
Is the master station connected on the network and operating
normally?
If an error has occurred at the master station, clear the master station error.
Is a station that is connected between the master station and
the NZ2AW1GNAL turned off or being remote reset?
If a station connected between the master station and the NZ2AW1GNAL is turned off or is
being remote reset, wait until the power is turned on and remote reset is completed.
Are the stations and switching hub between the master station
and the NZ2AW1GNAL linked up at the desired communication
speed?
Change the communication speed of the station or switching hub to meet the desired
communication speed.
Is the IP address of the NZ2AW1GNAL duplicated with another
device in the access range of CC-Link IE TSN?
Change the IP address so that no IP addresses are duplicated in the access range of CC-
Link IE TSN.
Do the IP address settings match?
Match the IP address of the NZ2AW1GNAL with the IP address specified in "Network
Configuration Settings" of "Basic Settings" of the master station.
Do the station types match?
Match the station type of the NZ2AW1GNAL with the station type specified in "Network
Configuration Settings" of "Basic Settings" of the master station.
Is the station a reserved station?
In "Network Configuration Settings" of "Basic Settings" of the NZ2AW1GNAL, set "Reserved/
Error Invalid Station" to "No Setting", and write the changed parameters to the CPU module.
Is the IP address of the NZ2AW1GNAL duplicated with other
stations?
If two or more stations are set to the same IP address, change them so that all IP addresses
are set differently.
Are the third to fourth octets of the IP address duplicated with
other stations in the "Network Configuration Settings" of the
"Basic Settings" of the master station?
Set the IP addresses for all stations so that the third to fourth octets of the IP addresses are
not duplicated.
Does the network address (subnet mask part of the IP address)
match the "Network Configuration Settings" of the "Basic
Settings" of the master station?
Set the IP address and subnet mask so that the network address of all stations match.
Is a station with a communication error connected between the
master station and the NZ2AW1GNAL?
Clear the error from the station with the communication error.
