The ramp output vi seems not to be ramping(correct attachment)

[Eugene Cameron]

I have a vi that should ramp the voltage from an inicial set voltage to a final set voltage over a period of time established by the user, but it seems to be jumping from the initial to final set with no ramp. I have attached the library in which it is included. (This time the correct attachment). Any ideas

Eugene;

If the ramping VI is working fine, the problem is probably in between the update of the data point array and the Analog Output channel.


I suggest you to have only the Analog Output VI outputing a known set of datapoints to check its operation. Once you are confortable with that portion, include the ramping VI, and keep monitoring the Update rate you are using, to make sure that all points of the array will be updated to the output.


Hope this helps.
