I need a library with industrial HMI drawings that can be used by visual C++ that can be incorporated in a HMI app

    Question

  • Hello,

    I am Developing a nice HMI that communicates with PLC;s an d DCS's automation and control systems using visual C++ 2008 and NModbus.dll lilbrary. The only thing I am still missing are the libraries for the HMI drawings,

    What I am looking for is for the typical HMI drawings like industrial tanks showing the level of the liquid contained ther, the drawing of a motor in motion or the typical bar indicating temperature or singnaling the value of a pressure signal.

    I know there are some free open source libraries that can be used by visual C++ 2008 so I would higly appreciate if somebody suggest me a good open source library with HMI drawings.

    Thanks a lot

  • If you want to search for source code, go to http://www.google.com/codesearch. For samples using a third party library, go to the library's web site such as http://www.nmodbus.com/Samples.aspx for the NModbus.dll library. If the library' claims to support Visual C++, ask or search how you can use it in Visual C++ on the library's web site.

    If you want reviews of industrial software libraries, search in some industrial magazines' web site or interview some people in the industry. You can also do a blog search, but generally blogs are less reliable than magezines.

    I downloaded the opc foundation because the OPC client lib are soooo!! expensive for me , but I find it very hard to use the class. I was wondering if you have a description or a code example so that I can see how I can perform the common tasks such as:

    Browse and find all the OPC servers running,  connect to the specified OPC server,  read and write data to the OPC server.

    I downloaded dll's such as OpcRcw.da.dll,  If you know somebody that has some documentation of those libraries, that would make my life really happy.

    By the way, I am using vc++2008

    Thanks in advance.
