Master station switching was instructed
to a station other than the standby
master station.
Temporary error invalid station
specification and line test requests were
issued before starting the link.
In the function started by SB/SW, an
attempt was made to execute the
function, which is
supported by only the master station, at
the local station.
A temporary error invalid station was
specified while the data link is being
performed upon automatic CC-Link
startup.
Data link restart (SB0000) was executed
for the station that was performing a data
link.
Data link stop (SB0002) was executed
for the station that had stopped a data
link.
Forced master to standby master
switching (SB000C) was executed in the
system where no standby master station
exists or in the system where the standby
master station had become faulty.
Forced master to standby master
switching (SB000C) was executed in the
system where all stations had become
faulty.
Forced master to standby master
switching (SB000C) was executed for
any station other than the master station.
Forced master switching (SB000C) was
instructed again while the master station
was being switched to the standby
master station.
The RLPASET instruction was executed
for a module whose parameters have
been set by GX Developer.
The parameter setting was changed
without turning the power supply to the
PLC system off and back on, or resetting
the PLC CPU.
The station number switch was outside of
the setting range.
The transmission rate setting switch is
set outside the range.
Corrective action
Set the correct parameters.
Set the contents of the
installation status and network
parameters to match.
Specify the station number that
corresponds to the standby
master station.
Issue the requests after the
data link is started.
Execute the corresponding
function from the master
station.
Specify a temporary error
invalid station while the data
link is performed with
parameters set using GX
Developer or the dedicated
instruction.
Execute Data link restart
(SB0000) for the station that
has stopped a data link with
Data link stop (SB0002).
Execute Data link stop
(SB0002) for the station that is
performing a data link.
After starting the data link of the
standby master station, execute
Forced master to standby
master switching (SB000C).
After starting the data link of the
standby master station, execute
Forced master to standby
master switching (SB000C).
Execute Forced master to
standby master switching
(SB000C) for the master
station.
Check ON/OFF of Forced
master switching (SB000C).
Use the RLPASET instruction
according to the procedure
below.
1. Clear the settings of the
network parameters and
refresh parameters of the
target module using GX
Developer.
2. Set the type of I/O
assignment setting in GX
Developer to "intelli."
3. Set switch 4 of the intelligent
function module switch
setting in GX Developer to
0100 .

4. Turn the power supply to the
PLC system off and back on,
or reset the PLC CPU.
Set the station number switch
