performed using an area where
Class3 communications
parameters were set.
0006H Class3 communications failed.
0101H A request for UCMM/Class3
communications failed to be sent.
0102H There was no response to a
request for UCMM/Class3
communications.
0103H Connection establishment for
Class3 communications failed.

response code.
Action
• Check the value set for the request area.
• Check the value set for the argument of the module function block.
• Check the settings of the external device.
• Check that there is no noise on the line.
Check the Class3 communication parameters and change the connection destination from the
reserved station.
• Check that the area used is correct.
• Set Class3 communications parameters in the area used.
Perform UCMM communications using an area where Class3 communication parameters are not set.
• Check that the Ethernet cable is not disconnected.
• Check by using PING or a similar method that a module with the request source IP address exists
on the network.
• Check that the Ethernet cable is not disconnected.
• Check by using PING or a similar method that a module with the request source IP address exists
on the network.
• When UCMM communications are requested, check that the external device supports UCMM
communications.
• When Class3 communications are requested, check that the external device supports Class3
communications.
• Check that there is no noise on the line.
• Check by using PING or a similar method that a module with the request source IP address exists
on the network.
• When UCMM communications are requested, check that the external device supports the UCMM
communication server function.
• When Class3 communications are requested, check that the external device supports the Class3
communication server function.
• Refer to the manual for the external device and check that the external device is ready to receive a
request.
• Check that there is no noise on the line.
• Check that the request destination IP address set in the Class3 communications parameters is
correct.
• Check that the external device supports the Class3 communication server function.
• Check that there is no noise on the line.
• Check that the external device supports the Class3 communication server function.
• Refer to the manual for the external device and check that the external device is ready to receive a
request.
• Check that there is no noise on the line.
• Reduce the number of UCMM communication connections executed simultaneously.
• Execute again at a later time.
Refer to the manuals for the external device and the EtherNet/IP specification (THE CIP NETWORKS
LIBRARY Volume 1 Common Industrial Protocol (CIP
