Table 13.1 Error code list (4/6)
Cause of error occurrence (details)
The station number set with the station
number setting switches of the standby
master station differs from that set in the
"standby master station No." network
parameter of the master station, or the
station set in the "standby master station
No." network parameter of the master
station is a local station.
All stations were set as reserved stations.
The station number designated for the
standby master station is specified to a
station other than an intelligent device
station.
Reserved station 0 points setting has
been made in the remote net additional
mode.
Reserved station 0 points setting has
been made for the station that is not a
reserved station.
Remote I/O station points setting is 8/16
points in the remote net additional mode.
8/16 points setting has been made for
the station other than the remote I/O
station.
Make 8/16 points setting for the same
remote I/O station.
In the remote net additional mode, the
"maximum station number of ver. 1
compatible slave stations" is greater than
the "minimum station number of ver. 2
compatible slave stations" in the network
parameter setting.
Model illegal has occurred between the
master and local/standby master
stations.
• The mode differs between the master
and standby master stations.
• The local station is set to the remote
net additional mode, and the master
station is set to other than the remote
net additional mode.
• The local station is in the remote net
ver. 2 mode or remote net additional
mode, and the master station is in the
remote net ver. 1 mode.
At the time of parameter setting with
dedicated instruction, an illegal value has
been set to switch 5 of the intelligent
function module switch setting.
At the time of parameter setting with
dedicated instruction, the station type of
other than the remote I/O station has
been set in the remote I/O net mode.
The assignment of RX, RY, RWw or RWr
is greater than the maximum number of
points.
When the standby master station was
operating as the master station with the
master station duplex function, the
network parameter setting of the faulty
master station was changed.
The mode set in the control data of the
RLPASET instruction differs from the
mode set with switch 3 of the intelligent
module switch setting.
Corrective action
Change the parameter setting
of the master station, or change
the station number setting of
the local/standby master
station, and then reset the PLC
CPU of the local/standby
master station.
Check the reserved station
settings.
Specify the standby master
station as an intelligent device
station.
Change the mode to the remote
net ver. 2 mode.
Set the station of reserved 0
points setting as a reserved
station.
Change the mode to the remote
net ver. 2 mode.
8 points setting and 16 points
setting have been made for the
same remote I/O station.
Make either 8 points setting or
16 points setting for the remote
I/O station.
In the remote net additional
mode, make network parameter
setting so that the "maximum
station number of ver. 1
compatible slave stations" is
less than the "minimum station
number of ver. 2 compatible
slave stations".
After correcting the mismatch of
modes between the master and
local/standby master stations,
reset the PLC CPU.
Set a correct value to switch 5
of the intelligent function
module switch setting.
Set all station types to the
remote I/O station.
Check the numbers of RX, RY,
RWw and RWr points in the
station information setting.
Return the network parameter
setting of the master station to
the original value.
Check the control data of the
RLPASET instruction and the
switch 3 setting of the intelligent
module switch setting.
