Indicates the stop acknowledgment status of the cyclic
transmission.
Off: Not acknowledged (SB0003 is off)
On: Stop acknowledged (SB0003 is on)
Indicates the stop completion status of the cyclic transmission.
Off: Not completed (SB0003 is off)
On: Stop completed (SB0003 is on)
Indicates the parameter receive status.
Off: Receive completed
On: Not received
Indicates the status of the received parameters.
Off: Parameters normal
On: Parameters abnormal
Indicates the status of the transient transmission. (Valid when the
SB0047 is off.)
Off: Transient transmission by the control station
On: Transient transmission by the sub-control station
Indicates the parameter type.
Off: MELSECNET/10 parameter
On: MELSECNET/H parameter
On PLC to PLC network
Indicates the setting of "With data link by sub control station
when control station is down."
Off: Cyclic transmission made by sub control station when
control station fails.
On: Cyclic transmission not made by sub control station
when control station becomes faulty
On remote I/O network
Indicates the status of designating cyclic transmission when the
(multiplexed) remote master station fails.
Off: Cyclic transmission made by multiplexed remote sub-
master station when multiplexed remote master station
fails (multiplexed remote I/O network)
On: Cyclic transmission not made when remote master
station fails (remote I/O network)
Indicates whether or not there are any parameter settings for the
low-speed cyclic transmission.
Off: No settings
On: Settings exist
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 supplemental 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
supplemental settings of the common parameters).
(Valid when the SB0049 is off.)
Off: Normal transmission designation
On: Multiplex transmission designation
Indicates the transmission status.
