工业现场经常有符合CAN总线协议的设备,往往这类设备没有通讯协议。如何通过工业计算机对这类设备进行控制是首要解决的问题。讲述用VB中的Winsock控件编写客户端和服务器应用程序,只需设置控件的属性并调用其方法就可轻易连接到一台远程机器上去;并且还可在两应用程序间进行双向交换数据,完成两机间的通信。简单、快捷、安全的实现对该类设备的控制与监视。 Industrial sites often have devices that comply with the CAN bus protocol, often without such protocols. How to control such devices through industrial computers is the primary problem to be solved. About Winsock control with VB write client and server applications, just set the properties of the control and call the method can be easily connected to a remote machine; and can also be two-way exchange of data between applications to complete Communication between two machines. Simple, fast and safe to achieve this type of equipment control and monitoring.
