Description
Indicates the I/O master station setting (Common parameter
setting) of block 2. (Valid when SB0049 is OFF)
Off: No setting
On: Setting exists. (Station No. is stored in SW005D.)
Indicates whether or not the station is reserved. (Valid when the
SB0049 is off.)
Off: No reserved station
On: Reserved station exists
Turns off when the SW0064 to SW0067 are all "0."
Indicates the link scan mode (status of supplementary settings of
the common parameters).
(Valid when the SB0049 is off.)
Off: Normal mode
On: Constant scan mode
Indicates the transmission designation status (status of
supplementary 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
In the case of multiplex transmission, the status of each station
can be checked in Multiplex transmission status (1) (SW00B0 to
SW00B3) and (2) (SW00B4 to SW00B7).
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
When any faulty station exists, each station status can be
checked in Baton pass status of each station (SW0070 to
SW0073).
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
When any non-executing station exists, each station status can
be checked in Cyclic transmission status of each station
(SW0074 to SW0077).
Indicates the master station cyclic transmission status. (Includes
online loop test.)
Off: Master station cyclic transmission normal.
On: Master station cyclic transmission 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
