上位机PC与台达VFD-M变频器MODBUS RTU格式

通过labview程序的演示，进一步掌握生产者与消费者循环，该压缩文件中包含有如何控制箱子的移动，及方向的控制等(Through the LabVIEW program demonstration, further grasp the producers and consumers of circulation, the compressed file contains how to control the moving direction of the box, and control)

通过labview的PID功能块对伺服电机进行闭环控制(The PID function block via labview servo motor closed-loop control)

优点：1，PPI协议通讯速度快，比OPC ，PCAccess，Modbus 快4-5倍左右。(就这一条优点就足了，呵呵) 2，PLC端无需编写任何通讯程序。 3，可以直接对PLC进行，RUN STOP等操作。 4，本程序全部采用LABVIEW底层程序框图，没用调用任何的DLL ，API等。这点对你学习还是修改程序功能都很有帮助，方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)

说明：  该程序主要实现了，在labview中远程访问数据库的功能。(it can help us to query the database on line.)

说明：  labview调用dll实现QR二维码生成，包含dll说明等，可作为子vi直接使用-LabVIEW(calls the DLL implementation of QR code generation, including DLL, can be directly used as a sub VI)

labview 双通道信号采集和回放系统，可以实现信号采集，设置频率(labview dual-channel signal acquisition and playback system that can achieve signal acquisition, set the frequency)

说明：  OPC UA CLIENT,LABVIEW

说明：  labview数据采集 基于研华数据采集卡的数据采集labview程序设计(LabVIEW data acquisition)

基于labview8.6的希尔伯特变换高精度测量低信噪比条件下两路正弦波相位差(Labview8.6 based Hilbert transform high-precision measurement of the sine wave phase difference of the two low SNR)

用LABVIEW实现保存数据的功能，使数据不会没有了(LABVIEW save data, so that data would not be without)
