Appendix 3 List of Link Special Relay (SB) Areas
Description
Stores the moderate/major error occurrence status of the CPU module on each station.
(Including own station)
Off: No moderate/major error
On: Station with a moderate/major error exists
When this relay is turned on, the status of each station can be checked with 'CPU
moderate to major error occurrence status' (SW0080 to SW0083).
Depending on the link refresh timing, the update of 'CPU moderate to major error
occurrence status' (SW0080 to SW0083) 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.
Stores the operating status of the CPU module on each station. (Including own station)
Off: All stations are at RUN or STEP-RUN state
On: Station at STOP or PAUSE state, or station with a moderate/major error exists.
When this relay is turned on, the status of each station can be checked with 'CPU
operating status' (SW0084 to SW0087).
Depending on the link refresh timing, the update of 'CPU operating status' (SW0084 to
SW0087) 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.
Stores the minor error occurrence status of the CPU module on each station. (Including
own station)
Off: All stations normal or station with a moderate/major error exists.
On: Station with a minor error exists.
When this relay is turned on, the status of each station can be checked with 'CPU minor
error occurrence status' (SW0088 to SW008B).
Depending on the link refresh timing, the update of 'CPU minor error occurrence status'
(SW0088 to SW008B) 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.
Stores the power supply status for external power supply by the MELSECNET/H
Network module with external power supply function of each station. (Including own
station)
Off: No external power supplied to any station
On: External power supplied to station(s)
When this relay is turned on, the status of each station can be checked with 'External
power supply status' (SW008C to SW008F).
Depending on the link refresh timing, the update of 'External power supply status'
(SW008C to SW008F) 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.
Stores the module type of each station.
Off: Stations with MELSECNET/10 type module included
On: All stations with MELSECNET/H type module
(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.
• This register is enabled when 'Baton pass status of each station' (SB0070) is off.
Stores the path switching detection status.
Off: Path switching not detected
On: Path switching detected
When 'Clear loop switching count' (SB0009) is turned on, the stored value is cleared.
