Table 8.1 Error code list
Error code Description Corrective action
4000 to 4FFF
(Error detected by the programmable
controller CPU)
Take measures 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 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 CC-Link IE Controller
Network)
Take measures referring to the troubleshooting section of the CC-Link IE
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)
Execute a setup confirmation test to check whether the same station number
has been set for two or more stations or whether two or more control stations
exist.
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.
F10A Initial status (online test/offline loop test)
<During execution of an online test>
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
<During execution of an offline test>
Change the switch setting to online after the test has been completed.
F10B Duplicate station number error
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
F10C Duplicate control station error
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
F10D Offline status Review the mode setting, and change it to online.
F10E Number of receive error retries exceeded
Check for faulty cables, faulty hardware, incorrect cable wiring, and absence of
terminating resistor (in the case of the bus). In addition, check whether the
same station number has been set for two or more stations or whether two or
more control stations or remote master stations exist.
The setup confirmation test and loop test of network diagnosis are effective.
F10F Number of send error retries exceeded
F110
Timeout error
