可编程序控制器（PLC）是以微处理器技术为基础，综合计算机技术和自动控制技术发展起来的一种新型工业控制器，广泛应用于工业控制的各个领域。在现代化的工业生产设备中，有大量的数字量及模拟量的控制装置，例如电机的起停，电磁阀的开闭，产品的计数，温度压力流量的设定与控制等，在工业现场中采用可编程序控制器（PLC）来解决自动控制问题已成为最有效的方式之一。本文叙述了在进行PLC控制系统设计时应该注意的事项。

HIMA(黑马)F8652X1.1、系统规模 首先应确定系统是用PLC单机控制，还是用PLC网络控制，并由此计算PLC输入、输出点数 在确定PLC输入 输出点数时一般要在实际需要点数的基础上留有10%的余量。

1.2、负载类型 根据PLC输出端所带的负载是直流型还是交流型，是大电流还是小电流，以及PLC输出点动作的频率等因素来确定输出端采用继电器输出，还是晶体管输出，或品闸管输出不同的负载选用不同的输出方式，这对系统的稳定运行是很重要的。

HIMA(黑马)F8652X 1.3、存储容量 与速度 一般存储容量越大、速度越快的PLC价格就越高 我们在选择时不应盲目追求大容量高速度，而应根据系统的大小合理的选用PLC产品。

1.4、工作环境 工作环境是PLC工作的硬性指标。F8652X 自控系统将人们从繁忙的工作和恶劣的环境中解脱出来，就要求自控系统能够适应复杂的环境，诸如温度、湿度、噪音、信号、工作电压等，一定要选择适应实际工作环境的产品。

Programmable controller (PLC) is a new type of industrial controller based on microprocessor technology, integrated computer technology and automatic control technology, and is widely used in various fields of industrial control. In modern industrial production equipment, there are a large number of digital and analog control devices, such as motor start-stop, solenoid valve opening and closing, product counting, temperature pressure flow setting and control, etc., the use of programmable logic controller (PLC) in the industrial field to solve the automatic control problem has become one of the most effective ways. This paper describes the matters that should be paid attention to in the design of PLC control system.

HIMA(Dark horse)F8652X1.1, the system scale should first determine whether the system is controlled by a PLC single machine, or by a PLC network control, and thus calculate the PLC input and output points in determining the PLC input and output points generally in the actual need to leave a 10% margin on the basis of points.

1.2, the load type according to the PLC output of the load is DC or AC type, is a large current or a small current, and the PLC output point action frequency and other factors to determine the output of the relay output, or transistor output, or gate tube output of different loads choose different output mode, which is very important for the stable operation of the system.

HIMA(Dark horse)F8652X 1.3, storage capacity and speed The larger the general storage capacity, the faster the PLC price is higher we should not blindly pursue large capacity and high speed when choosing, but should choose PLC products reasonably according to the size of the system.

1.4, working environment Working environment is a hard indicator of PLC work. F8652X automatic control system will free people from busy work and harsh environment, it is required that the automatic control system can adapt to complex environment, such as temperature, humidity, noise, signal, working voltage, etc., must choose products that adapt to the actual working environment.
