Description
Stores the baton pass status of each station.
Off: All stations normal
On: Faulty station exists
When this relay is turned on, the status of each station can be checked with 'Baton pass
status' (SW0070 to SW0073).
Depending on the link refresh timing, the update of 'Baton pass status' (SW0070 to
SW0073) may be offset by one sequence scan.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
• Reserved stations and stations exceeding the maximum station number are ignored.
Stores the data link status for each station.
Off: Data link in progress for all stations
On: Data link not in progress for some stations
When this relay is turned on, the status of each station can be checked with 'Data link
status' (SW0074 to SW0077).
Depending on the link refresh timing, the update of 'Data link status' (SW0074 to
SW0077) may be offset by one sequence scan.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
• Reserved stations and stations exceeding the maximum station number are ignored.
Stores the parameter communication status of each station.
Off: Parameter communication not in progress
On: Parameter communication in progress
When this relay is turned on, the status of each station can be checked with 'Parameter
communication status' (SW0078 to SW007B).
Depending on the link refresh timing, the update of 'Parameter communication status'
(SW0078 to SW007B) may be offset by one sequence scan.
(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.
• Reserved stations and stations exceeding the maximum station number are ignored.
Stores the low speed cyclic communication status.
It indicates that transmission was performed when the bit of either SB007A or SB007B is
turned on.

(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 status of each station.
Off: There is no station where a parameter error is detected.
On: There is a station where a parameter error is detected.
When this relay is turned on, the status of each station can be checked with 'Parameter
error status' (SW007C to SW007F).
Depending on the link refresh timing, the update of 'Parameter error status' (SW007C to
SW007F) may be offset by one sequence scan.
(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.
• Reserved stations and stations exceeding the maximum station number are ignored.
