PLC有五个方面的方便：

    （1）配置方便：可接控制系统的需要确定要使用哪家的PLC，那种类型的，用什么模块，要多少模块，确定后，到市场上定货购买即可。

    （2）安装方便：PLC硬件安装简单，组装容易。外部接线有接线器，接线简单，而且一次接好后，更换模块时，把接线器安装到新模块上即可，都不必再接线。内部什么线都不要接，只要作些必要的DIP开关设定或软件设定，以及编制好用户程序就可工作。

    （3）编程方便：PLC内部虽然没有什么实际的继电器、时间继电器、计数器，但它通过程序（软件）与系统内存，这些器件却实实在在地存在着。其数量之多是继电器控制系统难以想象的。即使是小型的PLC，内部继电器数都可以千计，时间继电器、计数也以百计。而且，这些继电器的接点可***次地使用。PLC内部逻辑器件之多，用户用起来已不感到有什么限制。考虑的只是入出点。而这个内部入出点即使用得再多，也无关紧要。大型PLC的控制点数可达万点以上，哪有那么大的现实系统？若实在不够，还可联网进行控制，不受什么限制。PLC的指令系统也非常丰富，可毫不困难地实现种种开关量，以及模拟量的控制。PLC还有存储数据的内存区，可存储控制过程的所有要保存的信息。……总之，由于PLC功能之强，发挥其在控制系统的作用，所受的限制已不是PLC本身，而是人们的想象力，或与其配套的其它硬件设施了。

PLC has five conveniences:

(1) Convenient configuration: It is necessary to determine which PLC to use, which type, which module to use, and how many modules to use when connecting to the control system. Once confirmed, you can order and purchase from the market.

(2) Easy installation: PLC hardware installation is simple and assembly is easy. The external wiring has a connector, which is simple to connect, and when replacing a module after one connection, the connector can be installed on the new module without the need for further wiring. Do not connect any internal wires, just make necessary DIP switch settings or software settings, and prepare user programs to work.

(3) Programming convenience: Although there are no actual relays, time relays, or counters inside the PLC, these devices actually exist through the program (software) and system memory. The number of them is unimaginable for relay control systems. Even for small PLCs, the number of internal relays can be counted in thousands, while time relays and counts can also be counted in hundreds. Moreover, the contacts of these relays can be used * * * times. There are so many internal logic devices in PLC that users no longer feel any restrictions when using them. All that is considered is the entry and exit points. And it doesn't matter how much internal entry and exit points are used. The control points of a large PLC can reach over ten thousand, how can there be such a large real-world system? If it is not enough, it can be controlled online without any restrictions. The instruction system of PLC is also very rich, which can easily achieve control of various switching values and analog quantities. The PLC also has a memory area for storing data, which can store all the information to be saved during the control process In short, due to the strong functionality of PLC, its role in the control system is no longer limited by the PLC itself, but by people's imagination or other hardware facilities associated with it.
