Error Code List (Continued)
Error No. Description of error Corrective action
F11B Being disconnected
Review the parameters and switch settings. (Check whether there is
a parameter error and the corresponding station is set properly in
the control station.)
Check for faulty cables, faulty hardware, noises, incorrect cable
wirings, duplicate station numbers and duplicate control stations.
F11F Initial status (no baton addressed to host)
Review the parameters and switch settings. (Check whether there
is a parameter error and the corresponding station is set properly in
the control station.)
Check whether the MESLECNET/H and MELSECNET/10 network
modules are mixed. (Check the control station type.)
F122 Send failure (in the case of bus)
Check for the coaxial cable connection and its stability, the
connection of terminating resistors, and the cable faults.
F222 No free area in the receive buffer (buffer-full error)
Retry after a little while.
If the error recurs as a result of a retry, review the number of
transient communication times and the communication interval of
the entire system. Or the sending destination CPU error (receive
processing (END processing) etc.) has occurred.
F224 Receive data size error Make the send data size less than 2k bytes.
F225 Logical channel number error Set the logical channel number properly. (Setting range: 1 to 64)
F226 Channel number error
Set the corresponding channel number properly. (Setting range: 1 to
8)
F701
Designated station error
1) When sending a data: sent to station number 0.
When receiving a data: received the message not
destined to host station.
2) Designated control station is down and cannot
receive data.
Correct the destination station number.
F702
Send destination station number error
(Send destination number is out of range or station
No. 65 or higher number specified)
Correct the destination station number.
F703
Send destination group number error
(Out of send destination group numbers or 33 or
higher number (control data A1H) is specified)
Review the send destination group number.
F705
Send destination CPU error (send destination H/W
error)
Check the send destination CPU.
F707
Number of relay stations invalid
(Out of relay range or 8 or more stations of relay
destinations are specified)
Set stations to which data can be sent.
Review the system.
F709
Network number error at receiving
(Received network No. is invalid)
Review the network No. of parameters.
If the parameters are not set, the network No. is preset to 1 (default);
so check the network No. of the other stations.
F70b Response wait timeout Retry after a little while.
F7C1 Channel in use is used. (host)
The same channel cannot be used at the same time.
Change the channel number. Alternatively, do not use the same
channel at the same time.
F7C2 Target station channel in use
Retry the SEND instruction after a little while.
Check whether several instructions are sent to the same channel of
the target station from the host or the several stations.
F7C3
Arrival monitoring timeout
(When the number of resends is 0)
When this error occurs by the RECV instruction, increase the value
of the arrival monitoring time if another station is executing the
SEND instruction.
If the host station is the instruction execution station, increase the
value of the arrival monitoring time. However the error remains,
check the network and the target stations.
The RECV instruction is executed without turning ON the RECV
instruction execution request flag.
F7C4
No communication even if the resent for the
designated number of resends was executed.
Increase the value of the arrival monitoring time. If the error still
remains, check the network and the target stations.
F7C6 The channel number is out of the setting range.
Set the channel numbers of the host station and of the target station
within a range between 1 and 64.
