Description: Modbus 协议是应用于电子控制器上的一种通用语言。通过此协议，控制器相互之间、控制器经由网络（例如以太网）和其它设备之间可以通信。它已经成为一通用工业标准。有了它，不同厂商生产的控制设备可以连成工业网络，进行集中监控。 Modbus TCP协议是Modbus协议的另一版本，它于1999年被开发出来以允许Internet用户访问以太网设备。Modbus是OSI模型第7层上的应用层报文传输协议，它在连接至不同类型总线或网络的设备之间提供客户机/服务器通信。目前，可以通过下列三种方式实现Modbus通信：
由于结合了Modbus协议的简单性和100 M 以太网的高速度，Modbus TCP/IP展现了卓越的性能，这意味着将这种网络应用在实时性要求很高的场合，如I/O扫描，是可行的。Modbus通信透明性Modbus协议可以方便地在各种网络体系结构内进行通信，每种设备（PLC、HMI、控制面板、变频器、运动控制、I/O设备等）都能使用Modbus协议来启动远程操作，同样的通信能够在串行链路和TCP/IP以太网网络上进行，而网关则能够实现各种使用Modbus协议的总线或网络之间的通信。由此可见，Modbus协议实现了全方位的通信透明。

Description: labview通过OPC与三菱FX系列PLC通讯实例
opc服务器软件使用的是KEPServerEx试用版，使用DataSocket函数对PLC的数据项进行操作。
DataSocket函数中，填上正确的OPC格式的地址即可。
最主要的是先配置好OPC服务器，OPC必须能正常跟PLC通讯，这样DataSocket读写数据时就能正确进行了。
本人也是刚学OPC通讯方面的，借人家的三菱FX1N进行试验，由于条件有限，没有对PLC所有的软元件进行试验，只试验了 X M Y ，能正确读写。
本实验程序运行之前要先填好OPC数据项的地址，不然会出错。
地址格式为 opc://localhost/OPC服务器名称/通讯通道名称.装置名称.PLC数据项名称
如： opc://localhost/KEPware.KEPServerEx.V4/通讯试验通道.三菱plc.Y11
也可以用NI ServerExplorer 软件来连接OPC服务器，就可以看到地址格式了。-opc KEPServerEx DataSocket PLC

波方法， 避免了专门的参数估计过程， 在提高增益性能的同时有效降低了计算量。方法的性能通过对混沌电力
线通信下的单音干扰和多音干扰的有效抑制得到了验证。-For the chaotic parameter modulation (CPM) of the power line communication (PLC) in the narrow-band interference caused by harmonics, two-phase dynamic estimation methods with minimum phase space volume (MP SV) criterion estimate model parameters, calculation of volume. Toward this end, the unknown parameters into augmented state matrix of the joint Kalman filter, to avoid the special parameter estimation process, while improving the performance gain reduces the amount of calculation. Method of performance under the power line communication by chaotic multitone jamming tone interference and the effective suppression has been verified.

Description: 1.read_mpeg.m把mpg格式的视频存为一帧一帧的jpg格式的图像
2.im_fg_y.m是对文件进行阈值分割，可以自动读取图片并分割图像，显示效果。必要时可以做成函数用plc.m调用一次对多幅图片进行处理。
3.im_fg_b.m是对图像利用canny算子进行边缘检测，用于分析与显示。同样可以做成函数来调用。
4.pcl.m是对图像文件批处理，一次可以读入多幅图像，处理后再存储。
5.pcl1.m是调用边缘检测函数对一组图像进行分割并保存。
6.fg_y.m利用canny进行边缘检测的函数
注意：在分割程序中有图像裁剪的步骤，这是作者在处理特定图片需要，请读者根据自己的情况进行修改。-The image 2.im_fg_y.m 1.read_mpeg.m mpg format video saved as a jpg format of a file threshold segmentation can automatically read the image and segmented image display.
