H
An error packet of ICMP was received. (An IP assembly
C04A
H
timeout error has occurred in the connected device.)
An IP assembly timeout error has occurred. (The
C04B
remaining part of the divided data could not be received
H
and a timeout has occurred.)
Because there is no space in the internal buffer, such as
C04C
H
the IP header buffer, data cannot be sent.
• In communications using an auto-open UDP port or
communications using a fixed buffer in the "No
Procedure" control method, there is an error in the
C04D
H
data length specified in the application data of the
message received by the Ethernet module.
• Not all the receive data can be stored.
CHAPTER 16 TROUBLESHOOTING
Action
• Check the operation of the connected device.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• Check the operation of the connected device.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• Check the operation of the connected device.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• Check the operation of the connected device.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• Check the operation of the connected device.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• Check the operation of the connected device.
• Because there may be congestion of packets on the line, send
data after a certain period of time.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• If an alive check timeout occurs, correct the IP assembly timer
value of the connected device.
• Check the operation of the connected device.
• Because there may be congestion of packets on the line, send
data after a certain period of time.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• If an alive check timeout occurs, correct the IP assembly timer
value of the connected device.
• Check the operation of the connected device.
• Because there may be congestion of packets on the line, send
data after a certain period of time.
• Check if the cable is disconnected.
• Check if there is a problem with the connection to the transceiver
or terminating resistor.
• Correct the IP assembly timer value and perform the initial process
again.
• Send the same data again and check the receipt of a response.
• Correct the data length.
• Correct the text size so that the text data size is within the receive
buffer memory size.
