      Information

      Overview Manuals Common Applications Product Precautions
      B&R X20HB8884 is a compact POWERLINK link selector that connects a POWERLINK device to a redundant cable network. Its two shielded RJ45 interfaces select the higher-quality network path while supporting 100BASE-TX communication at 100 Mbit/s.
      • Connects a standard POWERLINK device to two redundant cable paths
      • Selects the available higher-quality network line during operation
      • Provides two shielded 100BASE-TX RJ45 interfaces
      • Reports module and bus function through dedicated status indicators

      Install B&R X20HB8884 with X20PS8002, X20TB12, the documented X20BB81 or X20BB82 base and the required hub expansion module. Preserve both redundant cable paths, segment lengths and port assignments, then prove communication through each path separately.

      Important Notice: Confirm B&R X20HB8884, terminal hardware, field wiring, installed accessories and current B&R documentation before commissioning.

      Important Notice: The first document is an Apter Power model-specific technical reference; the second is the B&R official data sheet identified in the manufacturer source record.

      Redundant machine network
      B&R X20HB8884 attaches a POWERLINK device to two cable paths without requiring a looped ring.
      Tree-topology redundancy
      The link-selector arrangement supports redundant POWERLINK branches in documented tree structures.
      Availability retrofit
      An existing POWERLINK device gains dual-path connectivity through the compact link-selector assembly.
      Network-path commissioning
      Separate path tests confirm continued data transfer after either documented cable route is interrupted.
      Read the applicable B&R instructions before work. Verify B&R X20HB8884 and the installed X20 Redundancy System configuration.
      1
      Verify B&R X20HB8884 identity, both RJ45 port assignments and the redundant-network drawing.
      2
      Place the controlled process and both POWERLINK paths in the approved maintenance state.
      3
      Use X20PS8002, X20TB12 and the documented X20BB81 or X20BB82 bus base.
      4
      Install the required X20HB2880 or X20HB2885 expansion hardware for the selected architecture.
      5
      Keep every 100BASE-TX segment at or below the documented 100 m limit.
      6
      Preserve shield continuity, cable category, connector labeling and separation from interference sources.
      7
      Confirm module-status and bus-function indications before fault-injection tests.
      8
      Interrupt each cable path separately and verify uninterrupted communication, recovery and diagnostic reporting.

      FAQS

      • What network function does B&R X20HB8884 provide?
        It is a compact link selector that connects a POWERLINK device to a redundant POWERLINK cable system.
      • How many network ports are on B&R X20HB8884?
        The module provides two shielded RJ45 interfaces for the redundant 100BASE-TX paths.
      • Does B&R X20HB8884 use full-duplex Ethernet?
        No. The official technical data specifies half-duplex operation, with autonegotiation and Auto-MDI/MDIX supported.
      • What cable length limit applies to B&R X20HB8884?
        Each segment between two stations is limited to 100 m under the documented 100BASE-TX arrangement.
      • Which hardware is mandatory around B&R X20HB8884?
        B&R lists X20PS8002, X20TB12, X20BB81 or X20BB82 and the required X20HB2880 or X20HB2885 expansion module.
      • How does B&R X20HB8884 choose a redundant path?
        The integrated link-selector function transfers data over the highest-quality available network line.
      • What delay does B&R X20HB8884 introduce?
        The documented hub propagation delay is 0.96 to 1 microsecond.
      • How should B&R X20HB8884 redundancy be accepted?
        Prove normal traffic first, then interrupt each path independently and verify communication continuity, recovery and the expected status indications.
