FISHER-ROSEMOUNT KJ3002X1-BB1是一款Fisher-Rosemount品牌的PLC（Programmable Logic Controller，可编程逻辑控制器），主要用于工业自动化控制。

这款PLC有两种使用方式，专用和兼用。在专用模式下，PLC只用于采集、处理、存贮及传送数据。在兼用模式下，PLC在实施控制的同时，也可实施其他操作。

PLC可以用于远程控制。它具有多种通讯接口，具有很强的联网、通讯能力，并不断有新的联网的模块与结构推出。因此，使用FISHER-ROSEMOUNT K2002X1-CA1 PLC进行远程控制是很方便的。PLC可以与其他的PLC组成控制网，进行数据交换和操作。同时，它也可以与智能传感器、智能执行装置（如变频器）组成设备网，进行远程控制。

此外，这款PLC还可以与可编程终端联网、通讯，将数据在其上显示，或通过它向PLC写入数据，使其成为人们操作PLC的界面。同时，它也可以与计算机通讯，利用计算机的处理及显示功能，实现计算机对控制系统的监控和数据采集。

It is a Fisher Rosemount brand PLC (Programmable Logic Controller) mainly used for industrial automation control.

This PLC has two usage options, dedicated and dual use. In dedicated mode, the PLC is only used for collecting, processing, storing, and transmitting data. In the dual mode, PLC can perform other operations while implementing control.

PLC can be used for remote control. It has multiple communication interfaces, strong networking and communication capabilities, and constantly introduces new networking modules and structures. Therefore, using FISHER ROSEMOUNT K2002X1-CA1 PLC for remote control is very convenient. PLC can form a control network with other PLCs for data exchange and operation. At the same time, it can also form a device network with intelligent sensors and intelligent execution devices (such as frequency converters) for remote control.

In addition, this PLC can also be connected and communicated with programmable terminals, displaying data on it, or writing data to the PLC through it, making it an interface for people to operate the PLC. At the same time, it can also communicate with computers, utilizing their processing and display functions to achieve computer monitoring and data collection of the control system.
