Station setting
(host)
When PLC to PLC network
Indicates the station type set with the parameter of the host's
network module.
Off: Normal station
On: Control station
When remote I/O network
Indicates the station type set with the parameter of the host's
network module.
Off: Remote I/O station or multiplexed remote sub-master
station

station
SB0047
(71)
Baton pass status
(host)
Indicates the host's baton pass status (transient transmission
enabled).
Off: Normal
On: Abnormal
When an error is identified, the cause of the error can be checked
in Baton pass status (host) (SW0047) and Cause of baton pass
interruption (SW0048).

(112)
Baton pass status
of each station
Indicates the baton pass status of each station. (Not applicable to
reserved stations and the station with the maximum station number
or higher)
Off: All stations normal
On: Faulty station exists
When any faulty station exists, each station status can be checked
in Baton pass status of each station (SW0070 to SW0073).
Depending on the timing of the link refresh, Baton pass status of
each station (SW0070 to SW0073) and the update may be offset
by one sequence scan.

SB0074
(116)
Cyclic transmission
status of each
station
Indicates the cyclic transmission status of each station. (Not
applicable to reserved stations and the station with the maximum
station number or higher)
Off: All stations are executing data linking
On: Stations that are not executing data linking exist
When any non-executing station exists, each station status can be
checked in Cyclic transmission status of each station (SW0074 to
SW0077).
Depending on the timing of the link refresh, Cyclic transmission
status of each station (SW0074 to SW0077) and the update may
be offset by one sequence scan.
