Description
Stores the transient transmission status.
Off: Transient transmission by the control station
On: Transient transmission by the sub-control station
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
Stores the parameter type that has been set.
Off: MELSECNET/10 parameter
On: MELSECNET/H parameter
Stores the operation specification when the control station fails.
Off: Cyclic transmission performed by the sub-control station
On: Cyclic transmission not performed by the sub-control station
Stores low speed cyclic parameter setting information.
Off: No setting
On: Set
Stores the station type (mode) of the control station.
Off: MELSECNET/10 mode, MELSECNET/H mode
On: MELSECNET/H extended mode
Stores the I/O master station settings status of block 1 (LX/LY setting (1)).
Off: No setting
On: Set
When this relay is turned on, the station number is stored in 'Block 1 I/O master station'
(SW005C).
(Conditions)
• This register is enabled when 'Data link error status of own station' (SB0049) is off.
Stores the I/O master station settings status of block 2 (LX/LY setting (2)).
Off: No setting
On: Set
When this relay is turned on, the station number is stored in 'Block 2 I/O master station'
(SW005D).
(Conditions)
• This register is enabled when 'Data link error status of own station' (SB0049) is off.
Stores the reserved station setting status.
Off: No setting
On: Set
When this relay is turned on, the status of each station can be checked with 'Reserved
station setting' (SW0064 to SW0067).
Depending on the link refresh timing, the update of 'Reserved station setting' (SW0064 to
SW0067) may be offset by one sequence scan.
(Conditions)
• This register is enabled when 'Data link error status of own station' (SB0049) is off.
Stores the constant link scan setting status.
Off: No setting
On: Set
(Conditions)
• This register is enabled when 'Data link error status of own station' (SB0049) is off.
Stores the transmission specification status (the status of supplementary setting of
common parameters).
Off: Normal transmission specified
On: Multiplex transmission specified
(Conditions)
• This register is enabled when 'Data link error status of own station' (SB0049) is off.
Displays the transmission status.
Off: Normal transmission performed
On: Multiplex transmission performed
• When multiplex transmission is performed, each station status can be checked with
'Multiplex transmission status of forward loop side' (SW00B0 to SW00B3) and
'Multiplex transmission status of reverse loop side' (SW00B4 to SW00B7).
(Conditions)
This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior to
error is held.
