Error details
The IP address is not set for a CC-Link IE
module on the path that an IP packet takes.
• The CPU module on the path that an IP packet
takes does not support the IP packet transfer
function.
• Routing Parameters are set so that an IP
packet is routed to the CPU module that does
not support the IP packet transfer function.
• A network module on the path that an IP
packet takes does not support the IP packet
transfer function.
• Routing Parameters are set so that an IP
packet is routed to the network module that
does not support the IP packet transfer
function.
• The 3rd byte (Network No.) of the IP address
of the device on the path that an IP packet
takes overlapped with the network No. of the
module that is mounted with the CPU module
and does not support the IP packet transfer
function.
• The 3rd byte (Network No.) of the IP address
of the request destination device overlapped
with the network No. of the module that is
mounted with the CPU module and does not
support the IP packet transfer function.
• "IP packet transfer setting" in Built-in Ethernet
Port Setting tab of "PLC parameter" is not set.
• Routing Parameters are set so that an IP
packet is routed to the CPU module where IP
packet transfer setting is not set.
The IP communication test was started from the
CPU module other than the Built-in Ethernet port
QCPU.
The Built-in Ethernet port QCPU that performs IP
packet transfer is not the control CPU of the CC-
Link IE module, which is on the path that an IP
packet takes.
Corrective action
• Set the IP address to the control station or
master station of the CC-Link IE module.
• Check the communication status with the control
station or master station if the CC-Link IE
module is used as a normal station or local
station.
• Replace the control station or master station
with the one supporting the IP packet transfer
function.
• Conduct the IP communication test again after
the CC-Link IE module is started up.
• Check and correct the IP address of the request
destination device.
• Replace the CPU module with the one
supporting the IP packet transfer function.
• Correct Routing Parameters so that an IP packet
is routed to the CPU module that supports the IP
packet transfer function.
• Check and correct the IP address of the request
destination device.
• Replace the CC-Link IE module with the one
supporting the IP packet transfer function.
• Correct Routing Parameters so that an IP packet
is routed to the CC-Link IE module that supports
the IP packet transfer function.
• Check and correct the settings so that the 3rd
byte (Network No.) of the IP address of the
device on the path that an IP packet takes does
not overlap with the network No. of the module
that is mounted with the CPU module and does
not support the IP packet transfer function.
• Check and correct the settings so that the 3rd
byte (Network No.) of the IP address of the
request destination device does not overlap with
the network No. of the module that is mounted
with the CPU module and does not support the
IP packet transfer function.
• Check and correct the IP address of the request
destination device.
• Select "Use" for IP packet transfer function in "IP
packet transfer setting" in Built-in Ethernet Port
Setting tab of "PLC parameter".
• Correct Routing Parameters so that an IP packet
is routed to the CPU module where IP packet
transfer setting is set.
• Check and correct the IP address of the request
destination device.
Correct the setting so that the IP communication
test starts from the Built-in Ethernet port QCPU.
Set the Built-in Ethernet port QCPU that performs
IP packet transfer as the control CPU of the CC-
Link IE module, which is on the path that an IP
packet takes.
