Cause of error occurrence (details)
The station number was not specified during
temporary error invalid request/temporary
error invalid cancel request.
An error was detected in a remote
station, intelligent device station or
standby master station when a loop test
was performed.
A station number other than the head
station number was specified during
temporary error invalid request/temporary
error invalid cancel request.
All stations were in data link error status
when one of the following requests was
made:
• SB0000 (data link restart)
• SB0002 (data link stop)
The station number of the slave station is
outside of the range between "1 and 64".
The station number of the connected
module was duplicated (including
number of occupied stations).
However, this excludes the duplicate
head station number.
The station types of the module are
different from parameter settings.

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.
Corrective action

After correcting the parameters
of the master station, or the
local or standby master station,
reset the programmable
controller CPU.
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 request after the data
link is started.
