Description
Indicates the transmission designation status (status of
supplemental settings of the common parameters).
(Valid when the SB0049 is off.)
Off: Normal transmission designation
On: Multiplex transmission designation
Indicates the transmission status.
Off: Normal transmission
On: Multiplex transmission
Indicates the status of designating the multiplex remote function.
Off: Not designated.
On: Designated.
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
Turns off when the SW0070 to SW0073 are all "0."
Indicates the baton pass status of the master station. (Including
when there is an online loop test.)
Off: Master station baton pass normal.
On: Master station baton pass error.
Indicates the transient transmission status of the remote sub-
master station.
Off: Normal
On: Abnormal
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
Turns off when the SW0074 to SW0077 are all "0."
Indicates the master station cyclic transmission status. (Includes
online loop test.)
Off: Master station cyclic transmission normal.
On: Master station cyclic transimission error.
Indicates the cyclic transmission status of the remote sub-master
station. (Including the status at an online loop test)
Off: Cyclic transmission normal
On: Cyclic transmission abnormal
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
Turns off when the SW0078 to SW007B are all "0."
Indicates the low-speed cycle communication status.
It is indicated to have transmitted by turning the bit on for either
the SB007A or SB007B.
