    1747-BSN | Allen Bradley | SLC 500, Backup Scanner Module
    The "1747-BSN Plc Module New AB" refers to a new Allen-Bradley (AB) SLC 500 backup scanner module, which is used in redundant systems to provide automatic failover for Remote I/O (RIO). This module works in conjunction with a primary processor and secondary processor to ensure uninterrupted operation by taking over if the main module fails. It includes features like a configurable first channel for RIO or DH+, a second channel for RS-232/485, and a high-speed serial link for communication between redundant processors. 
    Key features of the Allen-Bradley 1747-BSN module: 
    • Function: Backup scanner module for redundancy in SLC 500 systems.
    • Compatibility: Works with SLC 5/02, 5/03, 5/04, and 5/05 processors.
    • Redundancy: Provides automatic failover for Remote I/O (RIO) networks.
    • Communication Channels:
      • Channel 1: Configurable as either RIO or DH+.
      • Channel 2: Configurable for RS-232/485 communication, often used for operator interfaces.
    • Failover Communication: Uses a High-Speed Serial Link (HSSL) for high-speed data transfer between primary and secondary processors.
    • Status Information: Includes a Local Serial Link (LSL) to share status between modules in the same chassis.
