Send new value if original value is changed

[Leukocyte]

Hey there,

I have programmed a sequence that sends commands to a power supply using VISA write to change the voltage. Every step in the sequence (for example 10 minutes at 100 V -> 5 minutes at 150 V -> ...) is represented by a case in a case structure. I want the user to be able to change the voltage during the run (to compensate small variations for example). How would I go about "send the programmed value, but as soon as the voltage control is changed by the user, send the new value"? I could use an event structure with "value change" as condition, but how then would I send the original value?

Have a nice day.

Sorry, my bad. I thought the question was too off-topic since the original thread was posted in the hardware/instrument control section and the question is more about general Labview logic. Please delete this thread.

When someone posts multiple times about the same problem to the same board it can be thought of as a chastisement; being that it's in another board you can think of it more as a redirection.  🙂
