系统相比，电气接线及开关接点已减少到数百甚至数千分之一，故障也就大大降低。此外，PLC带有硬件故障自我检测功能，

出现故障时可及时发出警报信息。在应用软件中，应用者还可以编入外围器件的故障自诊断程序，使系统中除PLC以外的电路及设备也获得故障自诊断保护。这样，整个系统的可靠性极高。

2.配套齐全，功能完善，适用性强

PLC发展到今天，已经形成了各种规模的系列化产品，可以用于各种规模的工业控制场合。除了逻辑处理功能以外，PLC大多具有完善的数据运算能力，

可用于各种数字控制领域。多种多样的功能单元大量涌现，使PLC渗透到了位置控制、温度控制、CNC等各种工业控制中。

加上PLC通信能力的增强及人机界面技术的发展，使用PLC组成各种控制系统变得非常容易。

3.易学易用，深受工程技术人员欢迎

PLC是面向工矿企业的工控设备。它接口容易，编程语言易于为工程技术人员接受。

梯形图语言的图形符号与表达方式和继电器电路图相当接近，

为不熟悉电子电路、不懂计算机原理和汇编语言的人从事工业控制打开了方便之门。

4.系统设计的工作量小，维护方便，容易改造

(1) 设计与维护

PLC用存储逻辑代替接线逻辑，大大减少了控制设备外部的接线，使控制系统设计及建造的周期大为缩短，

同时日常维护也变得容易起来，更重要的是使同一设备经过改变程序而改变生产过程成为可能。特别适合多品种、小批量的生产场合。

(2) 安装与布线

动力线、控制线以及PLC的电源线。

电源线是用作电气组件或设备与电源的连接线，通常来说指电线与其一端连接的插头或尾插的集合体，是电器产品的基本零部件之一。

电源线分为电线和插头两部分。

Compared with the system, the electrical wiring and switching contacts have been reduced to hundreds or even thousands of times, and the fault is greatly reduced. In addition, PLC with hardware fault self-detection function,

It can send alarm information in time when the fault occurs. In the application software, the user can also program the fault self-diagnosis program of peripheral devices, so that the circuit and equipment other than PLC in the system can also obtain fault self-diagnosis protection. In this way, the reliability of the whole system is extremely high.

2. Complete set, perfect function, strong applicability

PLC development to today, has formed a variety of scale of serialized products, can be used in various scales of industrial control occasions. In addition to logic processing functions, PLC mostly has perfect data computing capabilities,

It can be used in various digital control fields. A large number of various functional units have emerged, so that PLC has penetrated into various industrial controls such as position control, temperature control, CNC.

With the enhancement of PLC communication capability and the development of human-machine interface technology, it is very easy to use PLC to form various control systems.

3. Easy to learn and use, welcomed by engineering and technical personnel

PLC is an industrial control equipment for industrial and mining enterprises. Its interface is easy and the programming language is easy to be accepted by engineers and technicians.

The graphic symbol of ladder diagram language is quite close to the expression and relay circuit diagram.

It opens a convenient door for people who are not familiar with electronic circuits, do not understand computer principles and assembly language to engage in industrial control.

4. The workload of system design is small, easy to maintain and easy to transform

(1) Design and maintenance

PLC replaces wiring logic with storage logic, greatly reducing the wiring outside the control equipment, and greatly shortening the cycle of control system design and construction.

At the same time, routine maintenance is also made easier, and more importantly, it is possible to change the production process of the same equipment through the change procedure. Especially suitable for multi-variety, small batch production occasions.

(2) Installation and wiring

Power line, control line and PLC power line.

Power cord is used as an electrical component or equipment and power supply connection wire, usually refers to the plug or tail plug connected to one end of the wire, is one of the basic components of electrical products.

The power cord is divided into two parts: a wire and a plug.
