PLC控制器的优势

Advantages of PLC controller

1、使用方便,编程简单

1, easy to use, simple programming.

采用简明的梯形图、逻辑图或语句表等编程语言,而无需计算机知识,因此系统开发周期短,现场调试容易。另外,可在线修改程序,改变控制方案而不拆动硬件。

It uses simple ladder diagram, logic diagram or statement table programming language without computer knowledge, so the system development cycle is short and field debugging is easy. In addition, the program can be modified online to change the control scheme without dismantling the hardware.

2、功能强,性能价格比高

2, strong function, high performance price ratio.

一台小型PLC内有成百上千个可供用户使用的编程元件,有很强的功能,可以实现非常复杂的控制功能。它与相同功能的继电器系统相比,具有很高的性能价格比。PLC可以通过通信联网,实现分散控制,集中管理。

A small PLC has hundreds of programmable elements for users to use, has a strong function, can achieve very complex control functions. Compared with the relay system with the same function, it has a high performance price ratio. PLC can realize decentralized control and centralized management through communication networking.

3、硬件配套齐全,用户使用方便,适应性强

3, hardware complete, user convenience, adaptability.

PLC产品已经标准化、系列化、?榛,配备有品种齐全的各种硬件装置供用户选用,用户能灵活方便地进行系统配置,组成不同功能、不同规模的系统。PLC的安装接线也很方便,一般用接线端子连接外部接线。PLC有较强的带负载能力,可以直接驱动一般的电磁阀和小型交流接触器。

PLC products have been standardized, serialized, modular, equipped with a variety of hardware devices for users to choose, users can flexibly and conveniently configure the system to form different functions, different scales of the system. The installation wiring of PLC is also very convenient. The external wiring is usually connected with the wiring terminal. PLC has strong load capacity and can directly drive general solenoid valves and small AC contactors.

硬件配置确定后,可以通过修改用户程序,方便快速地适应工艺条件的变化。

After the hardware configuration is determined, the user program can be modified to adapt to the process conditions quickly and conveniently.

4、可靠性高,抗干扰能力强

4. High reliability and strong anti-interference ability.

传统的继电器控制系统使用了大量的中间继电器、时间继电器,由于触点接触不良,容易出现故障。PLC用软件代替大量的中间继电器和时间继电器,仅剩下与输入和输出有关的少量硬件元件,接线可减少到继电器控制系统的1/10-1/100,因触点接触不良造成的故障大为减少。

Traditional relay control system uses a large number of interte relays, time relays, because of poor contact, easy to break down. PLC replaces a large number of interte relays and time relays with software, leaving only a small number of hardware components related to input and output. The wiring can be reduced to 1/10-1/100 of the relay control system, and the fault caused by poor contact can be greatly reduced.

PLC采取了一系列硬件和软件抗干扰措施,具有很强的抗干扰能力,平均无故障时间达到数万小时以上,可以直接用于有强烈干扰的工业生产现场,PLC已被广大用户公认为可靠的工业控制设备之一。维修工作量小,维修方便

PLC has adopted a series of hardware and software anti-jamming measures, has a strong anti-jamming ability, the average trouble-free time is more than tens of thousands of hours, can be directly used in the industrial production site with strong interference, PLC has been recognized by the majority of users as one of the most reliable industrial control equipment. The maintenance workload is small and the maintenance is convenient.

PLC的故障率很低,且有完善的自诊断和显示功能。PLC或外部的输入装置和执行机构发生故障时,可以根据PLC上的发光二极管或编程器提供的信息迅速地查明故障的原因,用更换?榈姆椒ǹ梢匝杆俚嘏懦。

The failure rate of PLC is very low, and it has perfect function of self diagnosis and display. When the PLC or the external input device and the actuator fail, the cause of the fault can be quickly identified according to the inion provided by the LED or the programmer on the PLC, and the trouble can be quickly eliminated by replacing the module.
