DCS系统CI858 3BSE018136R1通信接口ABB模块
DriveBus 协议用于与 ABB 驱动器和 ABB 特殊 I/O 设备进行通信。DriveBus 通过 CI858 通信接口单元与控制器相连。DriveBus 接口用于 ABB 驱动器与 AC 800M 控制器之间的通信。DriveBus 通信专为 ABB 轧机驱动系统和 ABB 造纸机控制系统的分段驱动应用而设计。CI858 由处理器单元通过 CEX-Bus 总线供电,因此不需要额外的外部电源。

AC 800M and S800 I/O units are DIN-rail mountable. Each unit has a DIN rail locking mechanism that achieve mechanical locking and effective grounding. The additional screw lugs, located in the lower part of the units are used to provide extra fastening in environments subject to excessive vibrations. AC 800M units (CPU and communication interfaces) must be mounted on horizontal DIN rails. S800 I/O units can be mounted on both horizontal and vertical DIN rails. There are two ways of mounting AC 800M and S800 I/O in cabinets, open rack or other types of installations: • Mounting on DIN rail attached to a metal sheet • Mounting on prefabricated aluminium profile with DIN rail All conductive structural components of the installation must be bonded together with good and permanent connections for electrical safety and EMC reasons. The bonding should preferably be made with self-tapping cutting head screws. On painted surfaces where fastening is done by screw and nut, the paint must be removed from the contact surfaces. Apply conductive grease on surfaces to ensure a permanent connection. The cabinet/rack shall be properly connected to protective earth/ground.
