ABB CI856/3BSE026055R1 DCS可编程通讯单元
ABB CI856/3BSE026055R1 DCS可编程通讯单元
AC 800M通过通信接口CI856实现S100 I/O通信,ci 856通过基板与CEX总线相连。基板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。多达五个S100 I/O机架可以连接到一个CI856,其中每个I/O机架
可以容纳多达20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
一个主要优点是可以重复使用大部分现有I/O装置,包括现有ABB Master和Advant OCS装置中的终端和现场布线。单个连接到
S100 I/O单元,位于最多五个I/O机架中代码锁定设备,以防止安装不兼容的组件热插拔功能
The AC 800M realizes S100 I/O communication through the communication interface CI856, which is connected to the CEX
bus through the substrate. TP856 contains a ribbon connector, which connects to the bus expansion board in S100 I/O rack,
and provides simple DIN rail installation. Up to five S100 I/O racks can be connected to one CI856, where each I/O rack can
accommodate up to 20 I/O boards. CI856 is powered by the processor unit through CEX bus, so it doesn’t need any additional
external power supply. And advantages: one of the main advantages of CI856 interface is that it can reuse most of the existing
I/O devices, including the terminals and field wiring in the existing ABB Master and Advant OCS devices. A single device connected
to S100 I/O unit, located in up to five I/O racks, is code-locked to prevent the installation of incompatible component hot-plug functions.
