Appendix 7 Error Codes
When data linking cannot be performed using the cyclic transmission, or when
communication cannot be normally performed using the transient transmission with an
instruction of a sequence program or GX Developer, the error codes (hexadecimal) are
stored in the link special register or displayed on the GX Developer's system monitor.

Error Code List
Error No. Description of error Corrective action
F101 Initial status
F102 Initial status
F103 Initial status (during online test)
F104 Control/sub-control station shift status
F105 Initial status
Make SB0047 (baton pass status) and SB0049 (data link status)
turn off (normal).
Error No. turns off automatically when baton pass and data link
recover.
F106 Control/sub-control station shift status
Check the status of the control station's power supply, the cables
and the CPU status.
F107 Baton pass error (baton lost)
Check the line status for a faulty cable or the uninstalled
terminating resistor, as well as the stations that are not powered
on.
F108 Baton pass error (baton duplicated)
Check for the duplication of station numbers and control stations
with the setup confirmation test (Section 4.8.2).
Check for faulty cables, wire breakages, faulty connector
connections, connection errors, uninstalled or loose terminal
resistors, etc.
F109 Initial status (during online test)
F10A Initial status (online test/offline loop test)
Set to the online mode or stop the test.
F10B Station number duplication error Correct the station number.
F10C Control station duplication error Correct the control station setting.
F10D Offline status Set to online.
F10E Number of receive error retries exceeded
F10F Number of send error retries exceeded
F110 Timeout error
Check for faulty cables, faulty hardware, noises, incorrect cable
wirings, absence of terminating resistors (in the case of the bus),
duplicate station numbers and duplicate control stations.
F111 Corresponding station error
Review the status of the corresponding station, the parameter
settings and switch settings (to check if there is a parameter error
and the corresponding station is set properly in the control station).
F112 Faulty loop status
Check for faulty cables, faulty hardware, noises, incorrect cable
wirings, duplicate station numbers and duplicate control stations.
Check whether the MESLECNET/H and MELSECNET/10 network
modules are mixed. (Check the control station type.)
F113 Send failure
Retry after a little while.
If this error occurs as a result of a retry, check for faulty cables,
faulty hardware, noises, incorrect wirings, absence of terminating
resistors (in the case of the bus), duplicate station numbers and
duplicate control stations.
Review the parameters and switch settings. (Check whether there
is a parameter error and the corresponding station is set properly in
the control station.)
F114 Send failure
Retry after a little while.
If the error recurs as a result of a retry, check for faulty cables,
faulty hardware, noises, incorrect wirings, absence of terminating
resistors (in the case of the bus), and duplication of station
numbers and control stations.
F117 Send failure
Check for faulty cables, faulty hardware, noises, incorrect cable
wirings, absence of terminating resistors (in the case of the bus).
F118 Initial status (baton regeneration)
Wait until SB0047 (baton pass status) and SB0049 (data link
status) turn off (recover).
F11A Send failure (multiplex loop transmission stopped) Retry after a little while.
