7.4.2 Error code list of MELSECNET/10
The following table lists the error codes that are specific to the MELSECNET/H (MELSECNET/10 mode) remote I/O
station and that are not for the MELSECNET/10 remote I/O network.
For the other error codes, refer to the following.
Reference manual for the MELSECNET/10 network system used
Error code Description Corrective action
F224 Receive data size error
The cause is a failure of a module on the transient transmission source
station. Please consult your local Mitsubishi representative.
F226 Channel number error
Check the target-station storage channel (logic channel number) in the
control data on the station executing the SEND instruction.
F228 SEND instruction target station error
Check the target-station network number or the target station number in the
control data on the station executing the SEND instruction.
F7E1 Control data error
Check the set values (such as mode) in the control data of the dedicated
instruction.
F7E2 System error
The cause is a failure of the network module. Please consult your local
Mitsubishi representative.
F7E3 System error
The cause is a failure of the network module. Please consult your local
Mitsubishi representative.
F7E5 Post-transmission event wait timer time-out
Wait for a while and execute the REMFR/REMTO instruction again. Check
the operating status and network status of the target station, and the relay
station status (when sending the data to another network).
F7E7 Buffer memory address error
Check if the buffer memory address specified in the REMFR/REMTO
instruction is greater than 8000
H
.
F7E8 Network type error
Check if the network number specified in the REMFR/REMTO instruction is
not a PLC to PLC network.
F7E9 Instruction not executable error
Check if the data link of the host station is performed normally when the
REMFR/REMTO instruction is executed.
F82B
Network type mismatch error (control
station detected)
Change the network type of the normal station to the one set for the control
station.
F82C Parameter receive error
Change the system configuration because the parallel master system is
unavailable.
FD23 Data comparison error
Check if a faulty cable, hardware failure, miswiring, terminating resistor
problem (in a coaxial bus system), station number overlapping, or the
control station overlapping exists.
FD24 Retry over
Check if a faulty cable, hardware failure, miswiring, terminating resistor
problem (in a coaxial bus system), station number overlapping, or the
control station overlapping exists.
FD26 Light quantity error on the forward loop
The cause is a faulty cable. Connect a proper cable and perform the online
test.
FD27 Light quantity error on the reverse loop
The cause is a faulty cable. Connect a proper cable and perform the online
test.
FD28 RAM check error
The cause is a failure of the network module. Please consult your local
Mitsubishi representative.
FD29 ROM check error
The cause is a failure of the network module. Please consult your local
Mitsubishi representative.
FD2A Timer function check error
The cause is a failure of the network module. Please consult your local
Mitsubishi representative.
FD2B WDT function check error
The cause is a failure of the network module. Please consult your local
Mitsubishi representative.
