Table 8.1 Error code list (Continued)
Error code Description Corrective action
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, 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.
F112 Faulty loop status
Check for faulty cables, faulty hardware, and incorrect wiring. 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.
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, 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.
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, 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.
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
F115 Improper function code
Check for faulty cables, faulty hardware, and incorrect wiring. 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.
F116 Delayed online test processing
F117 Send failure
Check for faulty cables, hardware failure, noise, incorrect wiring, and absence
of terminating resistors (when a bus is used).
F118 Send failure (baton regeneration)
Wait until SB0047 (baton pass status)/SB0049 (data link status) is turned off
(normal).
F11A
Send failure
(multiplex transmission stopped)
Wait for a while and execute again.
F11B Being disconnected
Review the parameter and switch settings (to see if there is a parameter error
and the corresponding station is the control station or remote master station
and properly set).
Check for faulty cables, faulty hardware, and incorrect wiring. 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.
F11C System error
The hardware of the network module is faulty.
