Table 8.1 Error code list (continued)
Error No. Description of error Corrective measure
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.
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.
F10C Duplicate control station error
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
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
parameters of the error station.
When the operation mode for redundant system is debug, connect one of the
systems to the network. When connecting to both systems to the network, set
the operation mode to back-up mode or to separate mode.
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, absence of
terminating resistor (in the case of the bus), and duplication of station numbers,
control stations, and remote master stations.
The setup confirmation test and loop test of network diagnosis are effective.
F10F Number of send error retries exceeded
F110 Timeout error
F111
Corresponding station error
(Baton pass to the corresponding station
not executed)
Review the status of the corresponding station and the parameter and switch
settings (to see if there is a parameter error and the corresponding station is the
control station and properly set).
Confirm the power supply status of the corresponding station (to see if it is
repeatedly turned on and off).
Check for faulty cables, faulty hardware, incorrect cable wiring, absence of
terminating resistor (in the case of the bus), and duplication of station numbers,
control stations, and remote master stations.
The setup confirmation test and loop test of network diagnosis are effective.
F112 Faulty loop status
Check for faulty cables, faulty hardware, incorrect wiring, and duplication of
station numbers, control stations, and remote master stations.
Confirm the power supply status of each module (to see if it is repeatedly
turned on and off).
Confirm whether network modules in MESLECNET/H and MELSECNET/10
modes exist together (confirm the control station type).
F113
Send failure
(Baton pass to the host station not
executed)
Retry after a little while.
If the error reoccurs as a result of a retry, check for faulty cables, faulty
hardware, incorrect cable wiring, absence of terminating resistor (in the case of
the bus), and duplication of station numbers, control stations, and remote
master stations.
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
F114 Send failure
Retry after a little while.
If the error reoccurs as a result of a retry, check for faulty cables, faulty
hardware, incorrect cable wiring, absence of terminating resistor (in the case of
the bus), and duplication of station numbers, control stations, and remote
master stations.
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
