ABB CI854AK01 PROFIBUS-DP/V1 接口

PROFIBUS DP 是一种高速多用途总线协议（高达 12Mbit/s），用于互连现场设备，如远程 I/O、驱动器、低压电气设备和控制器。PROFIBUS DP 可通过 CI800A 通信接口连接到 AC 854M。经典CI854A包括两个PROFIBUS端口，以实现线路冗余，它还支持PROFIBUS主冗余。CI854B 是新的 PROFIBUS-DP 主站，可取代新安装中的 CI854A。

通过使用两个 CI854A 通信接口模块，在 PROFIBUS-DP 通信中支持主冗余。主冗余可以与 CPU 冗余和 CEXbus 冗余 （BC810） 结合使用。这些模块安装在DIN导轨上，直接与S800 I/O系统以及其他I/O系统接口，包括所有PROFIBUS DP/DP-V1和FOUNDATION现场总线熟练系统。

PROFIBUS DP 必须在最外层的两个节点处终止。这通常是通过使用具有内置端接的连接器来完成的。为了保证正确的工作端接，必须插入连接器并供电。

PROFIBUS DP is a high-speed multi-purpose bus protocol (up to 12Mbit/s) used to interconnect field devices such as remote I/O, drives, low-voltage electrical equipment, and controllers. PROFIBUS DP can be connected to AC 854M through the CI800A communication interface. The classic CI854A includes two PROFIBUS ports for line redundancy, and it also supports PROFIBUS master redundancy. CI854B is a new PROFIBUS-DP master station that can replace the newly installed CI854A.

By using two CI854A communication interface modules, primary redundancy is supported in PROFIBUS-DP communication. Main redundancy can be combined with CPU redundancy and CEXbus redundancy (BC810). These modules are installed on DIN rails and directly interface with the S800 I/O system and other I/O systems, including all Profibus DP/DP-V1 and FOUNDATION fieldbus proficiencies.

The PROFIBUS DP must terminate at the two outermost nodes. This is usually achieved by using connectors with built-in terminations. To ensure correct working termination, it is necessary to insert the connector and supply power.
