Other equipment of PLC system
1.Programming equipment:The programmer is an indispensable device for PLC development and application,monitoring operation,inspection and maintenance.It is used for programming,making some settings for the system,and monitoring the working status of the PLC and the system controlled by the PLC,but it does not directly participate in it.On-site control operation.Small programmer PLC generally has a hand-held programmer,and currently a computer(running programming software)is generally used as a programmer.
2.Human-machine interface:The simplest human-machine interface is the indicator light and button.At present,the integrated operator terminal of LCD screen(or touch screen)is more and more widely used,and the computer(running configuration software)acts as the human-machine interface.Very popular.
3.Input and output devices:used to permanently store user data,such as EPROM,EEPROM writer,bar code reader,potentiometer for input analog quantity,printer,etc.
PLC系统的其它设备
1、编程设备:编程器是PLC开发应用、监测运行、检查维护不可缺少的器件,用于编程、对系统作一些设定、监控PLC及PLC所控制的系统的工作状况,但它不直接参与现场控制运行。小编程器PLC一般有手持型编程器,目前一般由计算机(运行编程软件)充当编程器。
2、人机界面:最简单的人机界面是指示灯和按钮,目前液晶屏(或触摸屏)式的一体式操作员终端应用越来越广泛,由计算机(运行组态软件)充当人机界面非常普及。
3、输入输出设备:用于永久性地存储用户数据,如EPROM、EEPROM写入器、条码阅读器,输入模拟量的电位器,打印机等。
