Getting the right drivers it is possible to use Hart in applications like Excel. I know a lot of developers which are working with this option to setup simple test sequences for their devices very quickly. The scripting language is VBA (Visual Basic for Applications). If you like to get an example you should point your browser to the following url: http://borst-automation.com/Hart-Tools/UsingHartInExcel/ExcelUsingHart.pdf.
What do you think about this option? Are their any other applications which are of interest to be used for simple testing?
