A-B 81001-340-71-R应用领域

目前，PLC控制器在已广泛应用于钢铁、石油、化工、电力、建材、机械制造、汽车、轻纺、交通运输、环保及文化等各个行业，使用情况大致可归纳为如下几类。

A-B 81001-340-71-R开关量的逻辑控制

这是PLC控制器最基本、最广泛的应用领域，它取代传统的继电器电路，实现逻绢控制、顺序控制，既可用于单台设备的控制，也可用于多机群控及自动化线.如注塑机、印刷机、订书机械、组合机床、磨床、包装生产线、电镀线等。

A-B 81001-340-71-R模拟量控制

在T业生产过程当中，有许多连续变化的量，如温度、压力、流量、液位和速度等都是模拟量。为了使可编程控制器处理模拟量，必须实现模拟量(Analog)和数字量(Digital)之间的A/D转换及D/A转换。PLC厂家都生产配套的A/D和D/A转换模块，使可编程控制器用于模拟量控制。

运动控制

A-B 81001-340-71-R PLC控制器可以用于圆周运动或直线运动的控制。从控制机构配置来说，早期直接用于开关量/O模块连接位置传感器和执行机构，现在一般使用专用的运动控制模块。如可驱动步进电机或伺服电机的单轴或多轴位置控制模块。世界上各主要PLC控制器生产厂家的产品几乎都有运动控制功能，广泛用于各种机械、机床、机器人、电梯等场合。

过程控制

过程控制是指对温度、压力、流星等模拟量的闭环控制。作为工业控制计算机，PLC控制器能编制各种各样的控制算法程序，完成闭环控制。PID调节是一般闭环控制系统中用得较多的调节方法。大中型PLC都有PID模块，目前许多小型PLC控制器也具有此功能模块。PID处理一般是运行专用的PID子程序。过程控制在冶金、化工、热处理、锅炉控制等场合有非常广泛的应用。

数据处理

现代PLC控制有数学运算(含矩阵运算、函数运算、逻辑运算)、数据传送、数据转换、排序、查表、位操作等功能，可以完成数据的采集、分析及处理。这些数据可以与存储在存储器中的参考值比较，完成一定的控制操作，也可以利用通信功能传送到别的智能装置，或将它们打印制表。数据处理一般用于大型控制系统，如无人控制的柔性制造系统;也可用于过程控制系统，如造纸、冶金、食品工业中的一些大型控制系统。

A-B 81001-340-71-R Application field

At present, PLC controller has been widely used in steel, petroleum, chemical, electric power, building materials, machinery manufacturing, automobile, textile, transportation, environmental protection and culture and other industries, the use of the situation can be roughly summarized as the following categories.

A-B 81001-340-71-R Logic control of switching quantity

This is the most basic PLC controller, the most extensive application field, it replaces the traditional relay circuit, to achieve logic control, sequence control, can be used for single equipment control, can also be used for multi-machine group control and automation line. Such as injection molding machines, printing presses, stapler machines, combined machine tools, grinding machines, packaging production lines, electroplating lines, etc.

A-B 81001-340-71-R Analog control

In the production process of T industry, there are many continuously changing quantities, such as temperature, pressure, flow, liquid level and speed, which are analog quantities. In order for A programmable controller to handle Analog, it is necessary to realize A/D conversion and D/A conversion between analog and Digital. PLC manufacturers have produced supporting A/D and D/A conversion modules, so that programmable controllers are used for analog control.

Motion control

A-B 81001-340-71-R PLC controller can be used for circular or linear motion control. In terms of the configuration of the control mechanism, the early direct switch /O module is used to connect the position sensor and the actuator, and now the dedicated motion control module is generally used. For example, a single or multi-axis position control module that can drive a stepper motor or a servo motor. The products of the world's major PLC controller manufacturers almost all have motion control functions, which are widely used in various machinery, machine tools, robots, elevators and other occasions.

Process control

Process control refers to the closed-loop control of analog quantities such as temperature, pressure and meteors. As an industrial control computer, PLC controller can compile a variety of control algorithm programs to complete closed-loop control. PID regulation is a common method used in closed-loop control system. Large and medium-sized PLC have PID module, many small PLC controllers also have this function module. PID processing is generally run a special PID subroutine. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and so on.

Data processing

Modern PLC control has mathematical operations (including matrix operations, function operations, logic operations), data transmission, data conversion, sorting, table lookup, bit operation and other functions, can complete the data collection, analysis and processing. These data can be compared with the reference values stored in the memory to complete certain control operations, and can also be transmitted to other intelligent devices by means of communication functions, or they can be printed and tabulated. Data processing is generally used in large control systems, such as unmanned flexible manufacturing systems; It can also be used in process control systems, such as some large control systems in the paper, metallurgy, and food industries.
