set. (For UDP/IP)
C015H • The specified IP address of the external device for the
open processing is incorrect.
• The specified IP address of the external device of the
dedicated instruction is incorrect.
C016H The open processing of the connection specified for
pairing open has been already completed.
C018H The specified IP address of the external device is
incorrect.
C020H The send/receive data length exceeds the allowable
range.
C021H An abnormal end response was received for
communications using the fixed buffer and random
access buffer.

monitoring timer value.
• The connection with the external device was closed
while waiting for a response.
Action
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the same
error code is displayed again, the possible cause is a
hardware failure of the error module. Please consult
your local Mitsubishi representative.

Rewrite the module parameter using the engineering
tool. If the same error code is displayed again, the
possible cause is a hardware failure of the error module.
Please consult your local Mitsubishi representative.
• Correct the IP address setting value for the initial
processing.
• Check if the class of the IP address is set to A/B/C.
• Correct the subnet mask setting value for the initial
processing.
Correct the port numbers of the Ethernet-equipped
module and the external device.
Correct the port numbers of the Ethernet-equipped
module and the external device.
• Correct the specified IP address of the external device
of the CONOPEN/OPEN instruction. Set the class to A/
B/C.
• Execute the dedicated instruction again after
correcting the specified IP address of the external
device.
• Check that none of the connections targeted for pairing
open has been opened.
• Correct the combination of modules set for pairing
open.
Correct the specified IP address of the external device.
• Correct the data length to be sent.
• When the amount of data to be sent exceeds the limit,
divide the data into smaller chunks to send it.
• Check the command/response type of the subheader.
• Check the data length setting to be sent.
• Check if the communication data code setting of the
Ethernet-equipped module meets the binary/ASCII of
the message to be sent.
• Check the operation of the external device.
• Correct the response monitoring timer value of the
Ethernet-equipped module.
• Check the open status of the connection with the
external device.
