A-B罗克韦尔 1756-EWEB 增强型Web服务器模块 通讯主板模块

1756-EWEB 是以太网 I/P 增强型 Web 服务器模块。该模块是 Allen-Bradley 的 ControlLogix 产品系列的一部分。它具有一 (1) 个以太网 RJ-45 接口，支持 10/100 Mbps 传输速率。它占用 ControlLogix 机箱的一个插槽，支持安装到本地或分布式 I/O 机架。它使用 Studio 5000 编程软件和 RSLinx 通信管理进行配置

　　1．开关量逻辑控制

　　取代传统的继电器电路，实现逻辑控制、顺序控制，既可用于单台设备的控制，也可用于多机群控及自动化流水线。如注塑机、印刷机、订书机械、组合机床、磨床、包装生产线、电镀流水线等。

　　2．工业过程控制

　　在工业生产过程当中，存在一些如温度、压力、流量、液位和速度等连续变化的量（即模拟量），PLC采用相应的A/D和D/A转换模块及各种各样的控制算法程序来处理模拟量，完成闭环控制。PID调节是一般闭环控制系统中用得较多的一种调节方法。过程控制在冶金、化工、热处理、锅炉控制等场合有非常广泛的应用。

　　3．运动控制

　　PLC可以用于圆周运动或直线运动的控制。一般使用专用的运动控制模块，如可驱动步进电机或伺服电机的单轴或多轴位置控制模块，广泛用于各种机械、机床、机器人、电梯等场合。

The 1756-EWEB is an Ethernet I/P enhanced Web server module. The module is part of Allen-Bradley's ControlLogix product family. It features one (1) Ethernet RJ-45 interface and supports 10/100 Mbps transfer rates. It occupies a slot in the ControlLogix chassis and supports installation to local or distributed I/O racks. It is configured using Studio 5000 programming software and RSLinx communication management

1. Switch quantity logic control

Instead of the traditional relay circuit, it can realize logic control and sequence control, which can be used for the control of a single device, and can also be used for multi-machine group control and automatic pipeline. Such as injection molding machines, printing presses, stapler machines, combined machine tools, grinding machines, packaging production lines, electroplating lines, etc.

2. Industrial process control

In the industrial production process, there are some continuous changes such as temperature, pressure, flow, liquid level and speed (that is, the analog amount), PLC uses the corresponding A/D and D/A conversion modules and a variety of control algorithms to deal with the analog amount, complete closed-loop control. PID regulation is a kind of regulation method used in general closed-loop control system. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and so on.

3. Motion control

PLC can be used to control circular or linear motion. Generally use special motion control modules, such as single-axis or multi-axis position control modules that can drive stepper motors or servo motors, widely used in various machinery, machine tools, robots, elevators and other occasions.
