CI858K01 I/O单元进行通信通过CI858通信接口单

CI858K01是ABB公司生产的通讯模块，用于与ABB Drives和ABB Special I/O单元进行通信。它通过CI858通信接口单元连接到控制器，支持DriveBus协议。DriveBus接口专为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。

此外，CI858K01模块具有处理器单元，通过CE总线供电，因此不需要任何额外的外部电源。它还支持热插拔功能。 

继电器逻辑：当您通过硬接线进行互锁或逻辑（通过继电器或接触器的串联或并联组合）时。

PLC 逻辑：当您通过软件进行互锁或逻辑操作任何现场设备或通过 PLC 跳闸时。

过程控制系统使用两种不同类型的仪器：现场仪器和面板仪器。虽然这两种类型的乐器之间有一些相似之处，但也有许多重要的区别。

现场仪表和面板仪表的位置是它们之间的主要区别。现场使用的仪器通常位于现场外，靠近被监测或控制的过程。相比之下，面板仪表通常位于控制台或控制面板上，远离被监视或控制的过程。

这两种不同类型的仪器接收到的信号类型是一个重要的附加区别。温度、压力、流速和液位只是现场仪表可以测量和传输的过程变量的几个例子。它们通常内置传感器，可将物理参数转换为可发送到控制室的电信号。根据设备的类型，信号可能是数字的或模拟的。

现场仪表需要采用以下信号类型：2 线、4–20 mA 模拟输入/输出。使用数字输入：Potential Free contact。. 24 VDC 数字输出。平台控制系统必须为控制系统和其他面板之间的信号供电。带有 NAMUR 接口的接近开关就位。0.2 到 1.0 barg 是气动信号。如果该概念显示成本节约并满足快速响应的需要，则通过仪表现场总线进行数字通信是一种选择。

The CI858K01 is a communication module produced by ABB for communication with ABB Drives and ABB Special I/O units. It is connected to the controller via the CI858 communication interface unit and supports the DriveBus protocol. The DriveBus interface is designed for segment drive applications in ABB mill drive systems and ABB paper machine control systems.

In addition, the CI858K01 module has a processor unit that is powered through the CE bus, so no additional external power supply is required. It also supports hot swap.

Relay logic: When you are hardwired for interlocking or logic (by series or parallel combination of relays or contactors).

PLC logic: When you interlock or logically operate any field equipment through software or tripping through a PLC.

Process control systems use two different types of instruments: field instruments and panel instruments. While there are some similarities between the two types of instruments, there are also many important differences.

The location of field meters and panel meters is the main difference between them. Instruments used in the field are usually located off-site, near the process being monitored or controlled. In contrast, panel meters are usually located on a console or control panel, away from the process being monitored or controlled.

The type of signal received by these two different types of instruments is an important additional distinction. Temperature, pressure, flow rate, and level are just a few examples of process variables that field meters can measure and transmit. They typically have built-in sensors that convert physical parameters into electrical signals that can be sent to the control room. Depending on the type of device, the signal may be digital or analog.

Field meters require the following signal types: 2-wire, 4-20 mA analog input/output. Use numeric input: Potential Free contact. 24 VDC digital output. The platform control system must power signals between the control system and other panels. Proximity switch with NAMUR interface in place. 0.2 to 1.0 barg is a pneumatic signal. If the concept shows cost savings and meets the need for fast response, digital communication via an instrument fieldbus is an option.
