ABB CI856 通信接口模块

S100 I/O通信在AC 800M中通过通信接口CI856实现，该接口通过底板连接到CEX总线。底板 TP856 包含一个带状连接器，连接到 S100 I/O 机架中的总线扩展板，并提供简单的 DIN 导轨安装。多达 100 个 S856 I/O 机架可以连接到一个 CI20，其中每个 I/O 机架最多可容纳 <> 个 I/O 板。CI856 由处理器单元通过 CEX 总线供电，因此不需要任何额外的外部电源。

特点和优点

• CI856接口的一个关键优势是可以重复使用大部分现有I/O安装，包括现有ABB主控和Advant OCS装置中的端接和现场接线。
• 与多达五个 I/O 机架中的 S100 I/O 单元的单连接
• 密码锁定装置，防止安装不兼容的组件
• 热插拔功能

S100 I/O communication is achieved in AC 800M through communication interface CI856, which is connected to the CEX bus through a backplane. The backplane TP856 includes a ribbon connector that connects to the bus expansion board in the S100 I/O rack and provides a simple DIN rail installation. Up to 100 S856 I/O racks can be connected to a CI20, with each I/O rack accommodating up to<>I/O boards. The CI856 is powered by the processor unit through the CEX bus, so no additional external power supply is required.

Features and advantages

A key advantage of the CI856 interface is the ability to reuse most existing I/O installations, including termination and field wiring in existing ABB master and Advanced OCS devices.

Single connection to S100 I/O units in up to five I/O racks

Password locking device to prevent installation of incompatible components

hot plug capability
