1747-BSN Advantages
The Allen‑Bradley 1747‑BSN SLC 500 Processor Backup Scanner Module stands out from comparable scanner modules in several key areas.
Hot‑standby redundant RIO scanner capability. The Allen‑Bradley 1747‑BSN SLC 500 Processor Backup Scanner Module enables primary‑backup redundant RIO architecture; upon primary scanner failure, the backup unit takes over RIO link control to keep remote field I/O running for high‑availability systems.
HSSL high‑speed synchronization link. The Allen‑Bradley 1747‑BSN SLC 500 Processor Backup Scanner Module is equipped with HSSL port for fast retentive‑data synchronization between primary and secondary SLC‑500 processors, ensuring consistent control state before switch‑over.
Multi‑baud‑rate RIO network support. The Allen‑Bradley 1747‑BSN SLC 500 Processor Backup Scanner Module supports 57.6 kbps / 115.2 kbps / 230.4 kbps baud‑rate options, adapting to different RIO cable length and node‑quantity layout requirements.
Multi‑port redundancy for multiple communication paths. Besides RIO redundancy, the Allen‑Bradley 1747‑BSN SLC 500 Processor Backup Scanner Module supports DH+ and RS232 channel switch‑over for operator interface and SCADA connections, improving overall system fault tolerance.
Multi‑LED comprehensive diagnostic indicators. The Allen‑Bradley 1747‑BSN SLC 500 Processor Backup Scanner Module provides dedicated LED status for module health, RIO link, HSSL sync and fault alarm, allowing technicians to quickly judge primary‑backup working state and locate communication faults.
Native Allen‑Bradley 1747 SLC‑500 integration. As a factory‑original Allen‑Bradley 1747 series component, the Allen‑Bradley 1747‑BSN SLC 500 Processor Backup Scanner Module plugs directly into valid SLC‑500 chassis slots, works cooperatively with 1747‑ASB RIO adapters without extra conversion adapters.
