5 TROUBLESHOOTING
5.6 List of Error Codes
10EH to 10FH An error has occurred in TCP communications. • Retry at a later time.
• Check whether the operating status of the external device is
normal.
• Check for errors in the line status.
• The line may be busy, so retry at a later time.
• Reset the CPU module, and then switch it to RUN mode. If the
error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
• Check the settings of the connection with the external device.
110H Socket generation has failed. • Retry at a later time.
• Reset the CPU module, and then switch it to RUN mode. If the
error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
112H Incorrect send data has been specified. • Take measures to reduce noise.
• Reset the CPU module, and then switch it to RUN mode. If the
error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
113H There is insufficient cache memory available. • Retry at a later time.
• Restart the RJ71EIP91.
114H Failed to set the socket option (non-blocking). • Take measures to reduce noise.
• Reset the CPU module, and then switch it to RUN mode. If the
error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module. Please
consult your local Mitsubishi representative.
115H The frame size has exceeded the maximum size. • Use EtherNet/IP Configuration Tool to write the parameters to
the module again.
• When UCMM communications are performed, check whether
the setting details of the UCMM request area are correct.
119H A timeout occurred in the connection with the external device. • Check whether the operating status of the external device is
normal.
• Check for errors in the line status.
• The line may be busy, so retry at a later time.
• The external device may not be able to send data at the
specified RPI due to a high communication load, so specify a
larger RPI and connect again.
11AH An incorrect Forward Open service request has been received
from the external device.
• Check whether the operating status of the external device is
normal.
• Check for errors in the line status.
• The line may be busy, so retry at a later time.
• The external device may not be able to send data at the
specified RPI due to a high communication load, so specify a
larger RPI and connect again.
11BH Incorrect network parameters (originator to target) have been
received from the external device.
• Check whether the operating status of the external device is
normal.
• Check for errors in the line status.
• The line may be busy, so retry at a later time.
• The external device may not be able to send data at the
specified RPI due to a high communication load, so specify a
larger RPI and connect again.
11CH Incorrect network parameters (target to originator) have been
received from the external device.
• Check whether the operating status of the external device is
normal.
• Check for errors in the line status.
• The line may be busy, so retry at a later time.
• The external device may not be able to send data at the
specified RPI due to a high communication load, so specify a
larger RPI and connect again.
