LABVIEW与PLC的OPC通讯

labview采集数据,采用四通道方式进行采集，包含数据处理信息(LabVIEW collects data and uses four channels to collect data, including data processing information)

Labview双通道采集模拟电压，显示波形图并保存数据未TXT格式。(Labview Dual Channel Data Acquisition and Storage)

3σ准则 利用LabVIEW编写 剔除粗大误差(to Elimitate the gross error)

用于labview excel写入程序（源代码）(Write program for LabVIEW excel (source code))

利用Labview平台，实现了指定格式的xml与xls文件的互转功能，其中xml端利用Labview内部函数，xls端利用下载的dll函数。虽然不是通用互转系统，但仍然对labvie环境下xml编程和excel编程很有帮助。(The the Labview platform to achieve a specified format xml with the xls file Huzhuan function, in which the xml end to using Labview internal function, xls to end the use of the downloaded dll function. Although not the Universal Huzhuan system, but still helpful the xml programming labvie environment and excel programming.)

说明：  使用全局变量 VI 实现动态数据从一个 VI 传送到别一个 VI 中。当两个 VI 同时运行时，观察对比两个 VI 的波形图，调节第一个 VI 的滑动 杆，再观察对比两边的波形，最后，按下第一个 VI 里的停止按钮时，第二个 VI 也能接收到停止信号，并停止第二个 VI 的运行。(Using global variable VI to transfer dynamic data from one VI to another Medium. When the two VI are running at the same time, observe and compare the waveform of the two VI, and adjust the sliding of the first VI Then observe and compare the waveforms on both sides. Finally, when pressing the stop button in the first VI, the second VI It can also receive the stop signal and stop the operation of the second VI.)

采用LABview编写的信号处理程序，包括各种滤波去噪等功能(Using LABview signal processing procedures, including a variety of filtering de-noising, and other functions)

基于声卡的虚拟仪器示波器，通过声卡进行数据采集，再由LABview显示波形。(A virtual instrument oscilloscope based on sound card is used to collect data through a sound card, and then the waveform is displayed by LABview.)

labvIEW串口程序大全，可以为初学者提供良好的学习机会(LabvIEW serial procedures Daquan, you can provide good learning opportunities for beginners)

使用labview编程实现的串口通信，通过串口发送的命令控制相关设备进行数据传输和处理(Serial communication using LabVIEW programming, data transmission and processing through the serial port to send commands to control devices)
