CM902WL 用于开关量I/O模块连接位置传感器和执行机构

可编程逻辑控制器（PLC）的应用场景非常广泛，C0136-HZ主要包括以下几个方面：

开关量逻辑控制：这是PLC最基本、最广泛的应用领域，它取代了传统的继电器电路，实现逻辑控制、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流水线。如注塑机、印刷机械、组合机床、磨床、包装生产线、电镀流水线等。

模拟量控制：在工业生产过程当中，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：PLC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I/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。

过程控制：作为工业控制计算机，PLC能编制各种各样的控制算法程序，完成闭环控制。

数据处理：现代PLC具有数学运算（包括矩阵运算、函数运算和逻辑运算）、数据传输、转换、排序、查表和位运算等功能。它还可以完成数据的收集、分析和处理。

通信网络：可编程控制器的通信包括可编程控制器之间、可编程控制器与主机之间、可编程控制器与其他智能设备之间的通信。然后，通过网络连接形成集中管理信息的分布式网络系统。

位置控制：大多数PLC制造商提供单轴或多轴位置控制模块，用于拖动步进电机或伺服电机。该功能可广泛应用于各种机器，如金属切割机、金属成型机、装配机、机器人和电梯等。

此外，PLC还可以用于实现电气的控制以及用作PC系统和MCC系统的数据交换中心等。具体使用哪种类型的PLC，取决于具体应用需求。

Programmable logic controller (PLC) application scenarios are very wide, C0136-HZ mainly includes the following aspects:

Switching logic control: this is the most basic and most widely used field of PLC, it replaces the traditional relay circuit to achieve logic control and sequence control, which can be used for the control of a single device, and can also be used for multi-machine group control and automated assembly line. Such as injection molding machine, printing machinery, combined machine tools, grinding machines, packaging production lines, electroplating lines, etc.

Analog control: In the industrial production process, 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: PLC can be used to control circular motion or linear motion. In terms of the configuration of the control mechanism, the early I/O module was directly used to connect the position sensor and the actuator, and now the dedicated motion control module is generally used.

Process control: As an industrial control computer, PLC can prepare a variety of control algorithm programs to complete closed-loop control.

Data processing: Modern PLC has mathematical operations (including matrix operations, function operations and logical operations), data transmission, conversion, sorting, table lookup and bit operations and other functions. It can also complete the collection, analysis and processing of data.

Communication network: Communication of programmable controllers includes communication between programmable controllers, between programmable controllers and the host, and between programmable controllers and other intelligent devices. Then, through the network connection to form a centralized management of information distributed network system.

Position control: Most PLC manufacturers offer single – or multi-axis position control modules for towing stepper or servo motors. This function can be widely used in a variety of machines, such as metal cutting machines, metal forming machines, assembly machines, robots and elevators.

In addition, PLC can also be used to achieve electrical control and as a data exchange center for PC systems and MCC systems. The specific type of PLC used depends on the specific application needs.
