Virtual analog inputs? Possible? Just wondering whether it is possible to create 'virtual analog' signals, I am designign a system that uses a tank level sensor (pressure transducer); the component has not yet arrived and I am expecting it in a few weeks.

Is there any way to simulate the signals it would spit out, using some sort of GUI where I can physically control the 'virtual' tank level?

I'm thinking something along the lines of Wonderware's Intouch?

Would appreciate the help! Thanks
You don't specify the sensor you're trying to emulate, so we can't tell you exactly how to do it.

The obvious hardware approach would be a potentiometer.

You could also do it in software by writing a function to get the value, and temporarily replacing its implementation with one which generates random values, or reads values from a serial port, or reads them in order from a hard-coded array, or calculates them according to the time, or whatever you want.
