Cause of error occurrence (details)
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.
Parameter change was executed during
transient request.
A response from the requested station
was not returned within the watchdog
time period.
A transient request was made to a
remote I/O station or a remote device
station.
The receive buffer size of the dedicated
instruction is less than the response data
size.
The number of read/write points in the
control data of the dedicated instruction
is outside the setting range.
The station number in the control data of
the dedicated instruction is outside the
setting range.
Multiple dedicated instructions were
executed for the same station.
The setting of the interlock signal storage
device of the G(P).RIRCV or
G(P).RISEND instruction is outside the
setting range.
Data exceeding the receivable data size
were received with the message
transmission function.
An unsupported request was received.
There are too many transient requests to
the corresponding station.
There are too many transient requests to
the corresponding station.
Transient transmission was sent when a
loop test was in progress.
Transient storage buffer could not be
obtained.
There is an error in the target station's
CPU.
There are too many transient requests to
the corresponding station.
The target station was not an intelligent
device station.
A response was not received from the
requested station.
A transient transmission was executed
even though the target station was set to
the I/O mode.
The transmission destination and source
stations were the same when other
station connection was specified.
An error occurred in the transient storage
buffer when a transient transmission of
greater than 1 k was being performed.
A non-existing access code/attribute was
set.
An access code that does not exist was
used.
Corrective action
Check the control data of the
G(P).RLPASET instruction and
the switch 3 setting of the
intelligent module switch
setting.
Change the parameter after all
transient requests are
completed or before any are
requested.
Set a longer watchdog time. If
an error persists, check the
requested module and cables.
Set the corresponding station to
a local station or an intelligent
device station.
Check the receive buffer size.
Change the number of
read/write points to within the
setting range.
Change the station number to
within the setting range.
Check the program.
Change the setting of the
interlock signal storage device
to within the setting range.
Set a value of the received data
size or more for the receivable
data size.
Check the contents of the
request, as well as the target
station number.
Wait a while and then send the
requests (transient overload
status).
Wait a while and then send the
requests (transient overload
status).
Wait a while and then
retransmit.
Wait a while and then
retransmit.
Check the target CPU.
Wait a while and then
retransmit (transient overloaded
status).
Check if the target station is an
intelligent device station.
Check the requested module
and cables.
Set to the remote net mode.
Check the transmission
destination station number, or
change to host connection.
Wait a while and then
retransmit.
Set a correct access
code/attribute.
Use the correct access code.
