The Programmable Logic Controller (PLC) first appeared in the United States in the late 1960s. It was called PLC (Programmable Logic Controller) at that time and was designed to replace relays. To perform logical judgment, timing, counting and other sequential control functions. The concept of PLC was put forward by General Motors Corporation. PLC basic design idea is the computer function perfect, flexible, general advantages and relay control system simple, easy to understand, easy to operate, cheap advantages together, controller hardware is standard, general use. According to the actual application object, the control content is programmed into the user program memory of the controller to make the connection between the controller and the controlled object convenient.

2.3 PLC features and functions

(1) the main characteristics of PLC. PLC is characterized by reliable work, fast running speed, building block structure, flexible combination, good compatibility, simple programming and generation, rich, strong network function.

(2) the main functions of PLC. PLC system can complete the industrial real-time sequence control, condition control, counting control, step control and other functions; Capable of modular/digital (A/D), digital/modular (D/A) conversion, data processing, communication networking, real-time monitoring and other functions. Years of practice shows that PLC, reliable, is specially designed for the factory, with according to the requirements of the working environment reinforcement components, real-time scanning practice and fault diagnosis function, simple troubleshooting, deep preference of users. What makes a PLC so reliable is a real-time core or operating system of executable relay logic, sequential function diagrams, function blocks, structural text, command directories, or a combination of them. In the event of failure, the built-in device can maintain mechanical damage, and can maintain an orderly, predictable sequence.

2.4 PLC development trend: very fast logic operation and logic control, sequence control ability, in the discrete control of some reliability, convenient and easy to learn the programming method, so that it has an indisputable position in the discrete industrial automation field.

系统原理

◆ 交流电经交流配电分路进入整流部分;各整流模块整流得到的+24V直流电通过汇接进入直流配电，分多路提供给通信设备使用。

◆ 正常情况下，系统运行在并联浮充状态，即整流模块、负载、蓄电池并联工作，整流模块除了给通信设备供电外，还为蓄电池提供浮充电流。

◆ 当市电断电时， 整流模块停止工作，由蓄电池给设备供电维持设备的正常工作。

◆ 市电恢复后，整流模块重新给设备供电，并对蓄电池进行充电，补充消耗的电量。

◆ 监控模块采用集中监控的方式对交流配电、直流配电进行管理，同时通过RS485接口接收整流模块的运行信息并进行相应的控制。

◆ 监控模块还可通过RS485、RS232 方式连接本地计算机，并可通过Modem或其它传输资源(如公务信道等)联结监控中心，实现电源系统的集中监控组网。

冗余系统配置
（1）：安装软件

◆ 安装RSLogix5000/Studio5000软件，注意版本，RSLinx Classic软件会自动安装。

◆ 如果采用ControlNet架构，安装RSNetWorx for ControlNet软件。

◆ 安装冗余固件包，ControlFlash V14以上或者ControlFlash Plus工具

◆ 安装冗余配置工具RMCT

（2）：安装硬件

◆ 将电源模块、处理器、通讯模块和冗余模块安装到机架中。

◆ 两个机架中，相同模块的槽位要一致，建议冗余模块靠近处理器放置。

◆ ControlNet通讯模块节点通过拨码设置。

◆ 冗余模块光纤连接，光口没有顺序要求。

◆ 为电源模块连接电源。

（3）：与电脑建立连接

◆ 分别为2个机架上电。

◆ 使用USB电缆将处理器和电脑连接，在RSLinx Classic中可以看到机架和机架上的所有模块。

◆ 在RSLinx Classic中为以太网模块设置IP地址，改为静态。

◆ 也可以使用BootP-DHCP工具直接为以太网模块设置IP地址。

◆ 对应的以太网模块的IP地址、子网掩码、网关要一致。

◆ 在RSLinx Classic中建立Ethernet/IP驱动，可以通过以太网看到机架和机架上的所有模块。

Characteristics of servo motor

Dc brushless servo motor features

Small moment of inertia, low starting voltage, small no-load current; Abandon contact type reversing system, greatly improve the motor speed, high speed up to 100 000rpm; Brushless servo motor in the implementation of servo control, without encoder can also achieve speed, position, torque control; There is no wear of the brush, in addition to high speed, but also has a long life, low noise, no electromagnetic interference and other characteristics.

Dc brush servo motor features

1. Small size, quick action, quick response, large overload capacity, wide speed range

2. Low speed torque, small fluctuation, smooth operation

3. Low noise, high efficiency

4. The back-end encoder feedback (optional) constitutes DC servo and other advantages

5. Large range of variable voltage, adjustable frequency

The advantages of servo motor

First of all, let's take a look at the servo motor and other motors (such as stepper motor) compared with what the advantages of:

1. Precision: the closed-loop control of position, speed and torque is realized; The problem of stepping motor out of step is overcome.

2, speed: high speed performance, the general rated speed can reach 2000 ~ 3000 revolutions;

3, adaptability: strong anti-overload ability, can withstand three times the rated torque load, especially suitable for instantaneous load fluctuation and requirements of fast starting;

4, stability: low speed running smoothly, low speed running will not produce similar to the stepper motor stepper operation phenomenon. Suitable for high speed response requirements;

5, timeliness: motor acceleration and deceleration dynamic corresponding time is short, generally within tens of milliseconds;

6, comfort: heat and noise significantly reduced.

To put it simply: usually see the kind of ordinary motor, after the power cut it will turn for a while because of its own inertia, and then stop. And the servo motor and stepper motor is to stop, say to go, the reaction is very fast. But the stepping motor is out of step.
