• The CPU module and the Ethernet module cannot
communicate.
• The programmable controller CPU cannot process the
request from the connected device.
• Check the error code appended to the end code and
correct the error.

H
• The communication time between the CPU module and
the Ethernet module exceeded the CPU monitoring timer
value.
• Increase the CPU monitoring timer value.

• In communications using a fixed buffer, the remote
password of the port for the destination Ethernet module
is in the lock status.
• After unlocking the remote password using the MC
protocol, perform communications using a fixed buffer.
• Exclude ports used for communications using a fixed
buffer from the targets of the remote password check.

This request cannot be specified in connection with the
connected device.
• Correct the request details.
• Correct the open setting.

H
Contents of the request cannot be analyzed because the
text length or request data length is too short.
• Check and correct the text length or request data length of
the Qn header. Then send data to the Ethernet module
again.

• The IP address setting value of the E71 for the initial
process is incorrect.
• The setting value of the subnet mask field for the router
relay function is incorrect.
• Correct the IP address. Set the class to A/B/C.
• Correct the subnet mask.
C002

Some of the various timer setting values for the initial
process are outside the allowable range.
• Check and correct each timer setting value for the initial
process.
C003
H
The setting value of the auto-open UDP port number for
the initial process is outside the allowable range.
• Check and correct the auto-open UDP port number.
