Pulse breakpoint response on an NI-7344

I need to emit a pulse when a breakpoint is triggered, but I have a 7344 card.  Right now I have the card toggling the output voltage when the breakpoint is crossed.  How can I make the voltage toggle back after a specified amount of time?

Hello Kate,

I do not see a pulse breakpoint functionality for the 7340 series.  The 7350 does have this as an option for configuring the breakpoint.  If you have some other hardware that has PWM capabilities you can pass the trigger to that and use that signal to be a specific pulse width.  There is also an example program which modifieds a PWM signal on a motion controller at breakpoints.  You could potentially use the PWM signal to do what you want, however there is a small software delay between the PWM update and the breakpoint, so a strictly hardware solution would be more deterministic  Take a look at this link for Controlling the PWM output of a Motion Controller.

Hope this helps!  Good luck with your application.

In case it helps anyone in the future, I solved the problem by changing the breakpoint output with Set Breakpoint Output MOMO after a 100ms pause.
