Table 8.1 Error code list
Error No. Description of error Corrective measure
4000 to 4FFF
(Error detected by the programmable
controller CPU)
Take measures with referring to the QCPU User's Manual (Hardware Design,
Maintenance and Inspection).
7000 to 7FFF
(Error detected by the serial
communication module, etc.)
Take measures referring to the troubleshooting section of the Serial
Communication Module User's Manual.
B000 to BFFF (Error detected by the CC-Link module)
Take measures referring to the troubleshooting section of the CC-Link System
Master/Local Module User's Manual.
C000 to CFFF (Error detected by the Ethernet module)
Take measures referring to the troubleshooting section of the Ethernet Interface
Module User's Manual.
D000 to DFFF
(Error detected by the CC-Link IE Field
Network)
Take measures referring to the troubleshooting section of the CC-Link IE Field
Network User's Manual.
E000 to EFFF
(Error detected by the CC-Link IE
Controller Network)

Controller Network Reference Manual.
F101 Initial status (Network activated)
Wait until SB0047 (baton pass status) and SB0049 (data link status) turn off
(normal).
F102 Initial status (Network activated)
F103 Initial status (during online test)
F104
Initial status
(Control/sub-control station shift)
F105 Initial status (Parameters being processed)
F106
Shift from failed control station to sub-
control station
Check the condition of the control station's power supply and of the cables and
the status of the control station CPU module.
F107 Baton pass error (baton lost)
Check the line status for a faulty cable or a missing terminating resistor, as well
as the stations that are not powered on.
In the case of the PLC to PLC network, when transient transmission is
executed frequently and the link scan time may exceed 200 ms, adjust the
transient setting values to reduce the link scan time.
F108 Baton pass error (duplicate baton)
Check for duplicate station numbers and control stations with the setup
confirmation test.
If the setup confirmation test cannot be executed, identify the station where a
data link error has occurred in [Data-link status of each station] on the Other
station information screen of network diagnostics and then check the station
No. setting and parameters of the error station.
Check for faulty cables, wire breakage, poor connector connections, connection
errors, uninstalled or loose terminating resistors, etc.
F109 Initial status (during online test)
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
