Features:
- Ethernet event-data path to the SOE server
- RS-422 input for IRIG-B time synchronization
- Dual-redundant interface arrangement for supported FCS architectures
Yokogawa SB311 S1 connects a supported field control station to the Sequence of Events server and transfers timestamped event records.
Event transport and time synchronization use separate interfaces, so a healthy Ethernet connection does not by itself prove correct event timing.
Replacement planning must preserve the redundant slot arrangement, SOE server settings, Ethernet configuration, and the IRIG-B source used by the installed project.
Availability of Yokogawa SB311 S1 is subject to Apter Power inventory and sourcing confirmation.

SOE communication path
- Ethernet role: Carry event records from the FCS interface to the configured SOE server.
- Address record: Preserve approved network settings and server assignments before replacement.
- System scale: Compare connected supported FCS units with the documented server architecture.
- Event proving: Generate a controlled event and confirm receipt at the server.
IRIG-B verification
- Separate path: Treat RS-422 timing as independent from the Ethernet event-data link.
- Source health: Confirm the approved IRIG-B source and distribution equipment are operating.
- Wiring check: Inspect polarity, shielding, terminations, and continuity of the timing circuit.
- Timestamp test: Compare a known event with the project’s approved reference clock.
Pair acceptance
- Role capture: Record active and standby status before changing either module.
- Controlled swap: Use the maintenance procedure to prevent loss of event collection.
- Failover observation: Confirm event delivery and time alignment through a planned switchover.
- Final record: Save alarms, test events, timestamp comparison, and restored pair status.
