Error Code List (Continued)
Error No. Description of error Corrective action
F7C7
The host station number is specified in the target
station number.
Specify the target station number to the other numbers of the host
station’s.
F7C8
The execution type of designating all stations or
designating group is "With arrival confirmation".
For designating all stations or designating group, set the execution
type to "No arrival confirmation".
F7C9 The resend count is out of the setting range. Set the count within a range between 0 and 15 (times).
F7CA Arrival monitoring time setting out of range
Set the arrival monitoring time within a range between 0 and 32676
(seconds).
F7CB
The sent data length of the SEND instruction is out of
the setting range.
Set the sent data length within a range between 1 and 960 (words).
F800 Mode switch error
F801 Network number error
F803 Station number error
F804 DIP switch error
Correct the hardware setting switch and the parameter settings.
F820
Link parameter error
(The parameter contents are broken.)
Correct the common parameters or parameters specific to each
station.
F823 Parameter consistency error
Correct the common parameters or the parameters specific to each
station.
Correct the parameter size as follows.
Word number of specific parameters ≤ Word number of common
parameters
F826
Parameter mismatch
(The parameters of the control station started as a
normal station differs from the parameters received
from the sub-control station)
Review the parameters of the control station and reset the host
station.
F827 No automatic return
Perform a corrective action according to the setting of no automatic
return shift.
F828 No control station shift setting
Perform a corrective action according to the no control station shift
setting.
F832
Startup denied
(Startup on the condition of no startup)
If the data link is stopped by all station designation, all stations
starts.
If the data link is stopped by other station designation, stations do
not start automatically.
F833
Keyword error
(Started a different station from that is stopped)
Startup the station that is stopped.
Forcibly start it.
F837 Number of retries exceeded
Check the status of the control station.
(Check whether a reset or an error occurs in the middle of the
operation.)
F838 Relevant timer timeout
Check the status of the control station (whether a reset or an error
occurs in the middle of the operation)
F839
Communication impossible without link parameters
(SW0056 is 0)
Review the cause why the station is being disconnected.
F83A SW0000 out of range error Correct the contents of SW0000.
F842 Low speed consistency error
Correct the low speed link parameters or the low speed parameters
specific to each station
Correct the parameter size as follows.
Word number of specific parameters ≤ Word number of common
parameters
F906 Intermediate CPU error Check the intermediate CPU.
F982 Received data are not processed.
Check whether a station number of the target station or relay station
is correct.
(The CPU module of the relay station or target station that has
requested a transient transmission function, or the function
requested by the network module are not supported.)
FD01 CRC error (offline test)
FD02 Overrun error (offline test)
FD03 AB. IF error (offline test)
FD04 TIME error (offline test)
FD05 Data error (offline test)
FD06 Under error (offline test)
FD07 Send failure
Retry a test.
(If the error frequently occurs, check for faulty cables, faulty
hardware, noises, absence of terminating resistors (in the case of
bus), and incorrect wirings.)
