BC810 单元由两个基本部分组成：基板 （TP857） 和电源/逻辑板。底板是CEX总线连接器和外部电源所在的位置。它通过外壳的金属部件接地到 DIN 导轨。该板还带有外部功率投票二极管和保险丝。电源和逻辑板包含+3.3 V转换器、逻辑、CEX总线互连驱动器和互连电缆连接器。
BC810 可与 PM857、PM861A、PM862、PM863、PM864A、PM865、PM866、PM866A、PM867 和 PM891 一起使用。
在具有两个互连的 BC810 和主/备份 CPU 对的完全冗余系统中，BC810 支持在线更换 CPU 底板，而不会干扰 CEX 流量。如果必须更换 BC810，则到连接的 CEX 网段的所有流量都将停止。
CEX-Bus用于扩展带有通信接口单元的板载通信端口。也可以在CEX总线上使用冗余通信接口。CEX 总线互连单元 BC810 用于通过将 CEX 总线划分为单独的段来提高其可用性。这提高了具有冗余通信接口的系统的可用性。
• 支持冗余通信接口单元。
• 支持CPU的在线更换。
• 外部电源。
• 支持热插拔

The BC810 unit consists of two basic components: a substrate (TP857) and a power/logic board. The backplane is where the CEX bus connector and external power supply are located. It is grounded to the DIN rail through the metal components of the casing. The board also comes with external power voting diodes and fuses. The power and logic board includes a+3.3 V converter, logic, CEX bus interconnect driver, and interconnect cable connectors.
BC810 can be used with PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867, and PM891.
In a fully redundant system with two interconnected BC810 and primary/backup CPU pairs, BC810 supports online replacement of the CPU backplane without interfering with CEX traffic. If BC810 must be replaced, all traffic to the connected CEX network segment will stop.
CEX-Bus is used to expand onboard communication ports with communication interface units. Redundant communication interfaces can also be used on the CEX bus. The CEX bus interconnect unit BC810 is used to improve its availability by dividing the CEX bus into separate segments. This improves the availability of systems with redundant communication interfaces.
Support redundant communication interface units.
Support online replacement of CPUs.
• External power supply.
Support for hot swapping
