Error cause (details)
A function that is started using
SB/SW and executable on the
master station only was tried to
be performed on a local station.
A temporary error invalid station
was specified while data link was
being performed upon automatic
CC-Link startup.
Data link restart (SB0000) was
executed to the station that was
performing data link.
Data link stop (SB0002) was
executed to the station where
data link had been stopped.
Forced master switching
(SB000C) was executed in a
system where no standby master
station existed or the standby
master station was down.
Forced master switching
(SB000C) was executed in a
system where all stations were
faulty.
Forced master switching
(SB000C) was executed to a
station other than the master
station.
While the master station was
being switched to the standby
master station, Forced master
switching (SB000C) was
executed again.
The G(P).RLPASET instruction
was executed to a module where
parameters had been set using a
programming tool.
The parameter setting was
changed without powering off
and on the programmable
controller system or resetting the
CPU module.
The master station duplication
error canceling instruction was
executed while data link had
already been started.
The transmission speed test was
executed during data link.
Corrective action
Perform the function from the
master station.
Specify a temporary error invalid
station while data link is being
performed with parameters set
using a programming tool or
dedicated instructions.
Execute Data link restart
(SB0000) to the station where
data link has been stopped using
Data link stop (SB0002).
Execute Data link stop (SB0002)
to the station performing data link.
Start the data link of the standby
master station then execute
Forced master switching
(SB000C).
Start the data link of the standby
master station then execute
Forced master switching
(SB000C).
Execute Forced master switching
(SB000C) to the master station.
Correct the Forced master
switching (SB000C) setting.
Please consult your local
Mitsubishi representative.
Clear network parameter settings
for the target module using a
programming tool then set the
network parameters using the
G(P).RLPASET instruction.
