216GD61A HESG324430R11/B 可编程逻辑控制器,一种具有微处理器的数字电子设备，用于自动化控制的数字逻辑控制器，可以将控制指令随时加载存储器内存储与执行。可编程控制器由内部CPU，指令及资料存储器、输入输出单元、电源模块、数字模拟等单元所模块化组合成。PLC可接收（输入）及发送（输出）多种类型的电气或电子信号，并使用他们来控制或监督几乎所有种类的机械与电气系统。

外部设备是PLC系统不可分割的一部分，它有四大类

编程设备：有简易编程器和智能图形编程器，用于编程、对系统作一些设置、监控PLC及PLC所控制的系统的工作状况。编程器是PLC开发应用、监测运行、检查维护不可缺少的器件，但它不直接参与现场控制运行。

监控设备：资料监控器和图形监控器。直接监控资料或通过画面监控资料。

存储设备：有存储卡、存储磁带、软盘或只读存储器，用于永久性地存储用户资料，使用户程序不丢失，如EPROM、EEPROM写入器等。

输入输出设备：用于接收信号或输出信号，一般有条码读入器，输入模拟量的电位器，打印机等。

应用例：

半导体晶圆厂的各种自动化设备

大楼电梯

停车场机械设备

自动化生产线

中央空调

216GD61A HESG324430R11/B Programmable logic controller, a digital electronic device with a microprocessor, a digital logic controller for automatic control, which can load control instructions into memory at any time for storage and execution. The programmable controller is composed of internal CPU, instruction and data memory, input and output unit, power module, digital analog unit and so on. PLCS can receive (input) and send (output) many types of electrical or electronic signals and use them to control or supervise almost any kind of mechanical and electrical system.

External equipment is an integral part of the PLC system, it has four categories

Programming equipment: there are simple programmers and intelligent graphic programmers, which are used to program, make some Settings on the system, and monitor the working condition of the PLC and the system controlled by the PLC. The programmer is an indispensable device for PLC development and application, monitoring operation, inspection and maintenance, but it does not directly participate in field control operation.

Monitoring equipment: data monitor and graphics monitor. Monitor data directly or through the screen.

Storage device: memory card, storage tape, floppy disk or read-only memory, used to permanently store user data, the user program is not lost, such as EPROM, EEPROM writer, etc.

Input and output devices: used to receive signals or output signals, generally bar code readers, input analog potentiometers, printers, etc.

Application example:

Various automation equipment for semiconductor fabs

Building elevator

Parking lot machinery

Automated production line

Central air conditioning
