Control with single impulse

[Andutschi]

Hello,

I am using LabView to communicate with a Voltage Source (50kV) and some in and outputs.

I have an boolean which is true when the system detect a breakdown - voltage. The problem is that this boolean is only for a short time true, otherwise its false (only at the moment of the breakdown)

With the first true impulse, I would like to permanently control a relays with a true value.

Should I try to go with a RS Flip Flop or something like that?

Do you have any other suggestions for me?

Thank you very much!

Andy

Put the value in a shift register an OR it with the previous to keep it true after it is true once. Add a mechanism to reset.
