15 TROUBLESHOOTING
Detectability Error code
(hexadecimal)
Error details Cause of error occurrence (details) Corrective action
Master station Local station
B3A5 Mode invalid (parameter)
The mode set in the control data of the
G(P).RLPASET instruction differs from
the mode set with switch 3 of the
intelligent module switch setting.
Check the control data of the
G(P).RLPASET instruction and
the switch 3 setting of the
intelligent module switch
setting.
B401 Parameter change error
Parameter change was executed during
transient request.
Change the parameter after all
transient requests are
completed or before any are
requested.
B404 Response error
A response from the requested station
was not returned within the watchdog
time period. Set a longer watchdog time. If
an error persists, check the
requested module and cables.
B405
Transient applicable station
error
A transient request was made to a
remote I/O station or a remote device
station. Set the corresponding station to
a local station or an intelligent
device station.
B410 Receive buffer size error
The receive buffer size of the dedicated
instruction is less than the response data
size.
Check the receive buffer size.
B411 Data length outside of range
The number of read/write points in the
control data of the dedicated instruction
is outside the setting range. Change the number of
read/write points to within the
setting range.
B412
Station number outside of
range
The station number in the control data of
the dedicated instruction is outside the
setting range.
Change the station number to
within the setting range.
B413 Request error
Multiple dedicated instructions were
executed for the same station.
Check the program.
B414
Interlock signal data outside of
range
The setting of the interlock signal storage
device of the G(P).RIRCV or
G(P).RISEND instruction is outside the
setting range.
Change the setting of the
interlock signal storage device
to within the setting range.
B418 Received data size error
Data exceeding the receivable data size
were received with the message
transmission function. Set a value of the received data
size or more for the receivable
data size.
B601 Request type error An unsupported request was received.
Check the contents of the
request, as well as the target
station number.
B602
Transient request overload
error There are too many transient requests to
the corresponding station.
Wait a while and then send the
requests (transient overload
status).
B603
Transient request overload
error There are too many transient requests to
the corresponding station.
Wait a while and then send the
requests (transient overload
status).
B604 Loop test in processing
Transient transmission was sent when a
loop test was in progress. Wait a while and then
retransmit.
B605
Transient storage buffer could
not be obtained Transient storage buffer could not be
obtained. Wait a while and then
retransmit.
B607 Target station CPU error
There is an error in the target station's
CPU.
Check the target CPU.
B771
Transient request overload
error There are too many transient requests to
the corresponding station.
Wait a while and then
retransmit (transient overloaded
status).
B774 Transient request error
The target station was not an intelligent
device station. Check if the target station is an
intelligent device station.
B778 Response time out
A response was not received from the
requested station. Check the requested module
and cables.
B780 Module mode setting error
A transient transmission was executed
even though the target station was set to
the I/O mode.
Set to the remote net mode.
B782
Station number specification
error
The transmission destination and source
stations were the same when other
station connection was specified. Check the transmission
destination station number, or
change to host connection.
B783 Transient storage buffer error
An error occurred in the transient storage
buffer when a transient transmission of
greater than 1 k was being performed.
Wait a while and then
retransmit.
B801 Access code setting error
A non-existing access code/attribute was
set. Set a correct access
code/attribute.
B802 Access code error
An access code that does not exist was
used.
Use the correct access code.
