Description
Indicates the station type that is controlling cyclic transmission at
the remote I/O stations.
Off: Remote master station
On: Remote sub-master station
Indicates the parameter transmission status of each station. (Not
applicable to reserved stations and the station with the maximum
station number or higher)
Off: Executing communication other than parameter
communication
On: Executing parameter communication
Stations that are communicating parameters can be checked in
Parameter communication status of each station (SW0078 to
SW007B).
Indicates the low-speed cycle communication status.
It is indicated to have transmitted by turning the bit on for either
the SB007A or SB007B.
SB007A
SB007B
Cycle interval
Indicates the parameter status of each station. (Not applicable to
reserved stations and the station with the maximum station
number and higher)
Off: No station detected parameter errors
On: A station detected parameter errors
Stations that have parameter errors can be checked in
Parameter error status of each station (SW007C to SW007F).
Indicates the operation status of each station's CPU on the PLC-
to-PLC network (including the host station).
Off: All stations normal
On: A moderate or serous error identified
If a moderate or serious error is identified, the status of each
station can be checked in CPU operation status of each station
(1) (SW0080 to SW0083).
Indicates the operation status of each remote I/O station on the
remote I/O network (including the host station).
Off: All stations normal
On: Error station identified
If any error station is identified, the status of each station can be
checked in CPU operation status of each station (1) (SW0080 to
SW0083).
Indicates the CPU RUN status of each station.
Off: All stations are in the RUN or STEP RUN status
On: Stations in the STOP or PAUSE status exist
(including the host)
When some stations are in the STOP or PAUSE status, each
station status can be checked in CPU RUN status of each station
(SW0084 to SW0087).
Indicates the CPU run status of remote master station.
Off: Run or STEP RUN status
On: STOP or PAUSE status
