(or token) passing.
• Execute the dedicated instruction, interlocking with
Baton pass status (own station) (SB0047) and Baton
pass status of each station (SW00A0 to SW00A7).
• Check the Cause of baton pass interruption (SW0048)
at the own station and restart baton (or token) passing
before executing the transient transmission.
• If the error persists even after taking the above action,
please consult your local Mitsubishi representative.

Duplication of station No. and
control station setting of the
own station
Station No. and control
station setting of the own
station are duplicated.
• Change the station No. of the own or other station and
the control station setting.
• After taking the above action, reset the error station.
• After turning on the own station, turn on the other
stations to identify the station that has a duplicate
station No. and/or control station setting.
• When the redundant system is in debug mode, connect
only one of the two systems to the network. To connect
both systems to the network, set the operation mode of
the redundant system to backup or separate mode.

IP packet transfer function not
supported (IP communication
test)
The module in the station on
the route after the route
where an error has been
detected does not support the
IP packet transfer function.
• Check the first five digits of the serial number of the
module in the station on the route after the route where
an error has been detected, and check whether the
module in the station supports the function. If the
function is not supported, replace the module with the
one with the latest version.
