Temporary error invalid station
specification and line test requests were
issued before starting the link.
A temporary error invalid station was
specified while the data link is being
performed upon automatic CC-Link
startup.
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

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 baud rate setting was outside of the
setting range.
The station number (including the
number of occupied stations) of the
station information parameters was set to
"other than 1 to 40 ."
H H
The total number of occupied stations set
with the station information parameter
exceeded 64.
The number of all occupied stations in
the station information parameter was set
to "0".

parameter was set to "other than 0 to 2".
Write operation was performed to a use
prohibited area (not used) in the buffer
memory.
The number of remote device stations
was set to "43 stations or more" with the
station information parameter.
Corrective action
