DigiVac has been developing vacuum instrumentation with Ethernet connectivity for several years. In order to be able to share what we have done, we created a stand alone simulation applet and posted this on our website.
Anyone who has a Java enabled browser can click, download, run and interact with this software without needing to first purchase an Ethernet enabled instrument. The applet randomly assigns sensor values between the SP1 and SP2 set points. We have refined our Java Applet to allow real 2 way communication with our instruments from any Java Enabled Web Browser. This includes command line query and graphical simulation. We are very interested to hear what folks think.. please comment!
