Description

The BC810 unit consists of two basic parts: baseplate (TP857) and power supply/logic board. The baseplate is where the connectors to CEX-Bus and the external power reside. It is grounded to the DIN-rail through metal parts of the housing. The board also carries the external power voting diode and fuse. The power supply and logic board contain the +3.3 V converter, logic, drivers for CEX-Bus interconnection, and the connector for the interconnection cable.

The BC810 can be used with PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867 and PM891.

In a fully redundant system with two interlinked BC810 and primary/backup CPU pair, the BC810 support online replacement of the CPU baseplate without disturbing the CEX traffic. If the BC810 has to be replaced, all traffic to the connected CEX segment is stopped.

The CEX-Bus is used for extending the onboard communication ports with communication interface units. It is also possible to use redundant communication interfaces on the CEX-Bus. The CEX-Bus Interconnection unit BC810 is used to increase the availability of the CEX-Bus by dividing it into separate segments. This improves the availability of systems with redundant communication interfaces.

Features:

  • Supports Redundant Communication Interface Units
  • Supports On-Line Replacement of the CPU
  • External Power Supply
  • CEX-Bus Segmentation for Increased Availability
The BC810K02 kit contains two BC810 CEX-bus Interconnection Units, two TP857 baseplates, one TK851 one-meter interconnection cable, and two TB850 CEX-bus terminators. Each BC810 includes a baseplate with CEX-Bus connectors and power connections, while the electronic board incorporates the CEX-Bus interface, drivers, fuse protection, and an integrated 3.3 V power converter supplied from an external 24 V DC source.

The BC810K02 supports online CPU replacement in redundant AC 800M controller configurations. During CPU baseplate replacement, the BC810 maintains communication on the remaining CEX-Bus segments, allowing maintenance to be performed without interrupting the operation of the complete control system. If a BC810 itself is replaced, communication is interrupted only on the associated CEX-Bus segment while the remaining segments continue operating.

The BC810K02 3BSE031155R1 ABB CEX-bus Interconnection Unit may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

In a fully redundant system with two interlinked BC810 units and a primary/backup CPU pair, the BC810K02 supports online replacement of the CPU baseplate without disturbing the CEX traffic. However, if a BC810 unit within the BC810K02 has to be replaced, all traffic to the connected CEX segment will be disturbed. The BC810K02 improves system availability by enabling redundant communication interfaces on the CEX-Bus, which is used for extending the on-board communication ports with communication interface units.

FAQs

  • What is the main function of the BC810K02?

    +
    It increases system availability by dividing the CEX-bus into independent segments to support redundant communication interfaces
  • Which CPU modules are compatible?

    +
    It works with AC 800M controllers like the PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867, and PM891
  • Does it support hot-swapping?

    +
    Yes, it supports online replacement of the CPU baseplate without disrupting active CEX traffic. However, replacing the BC810 unit itself will halt traffic on its connected segment.
