Using time measures for trigger

[zaharoff]

Hi,

I'm trying to programm something to trigger a data record. I use a 6601 card to get times between 2 sensors. I use this to get 2 times. And I would like to trigger a data record with these times : start recording when the first time is not 0 and stop when the second is not 0. For this, I've tried like that :

The 2 signals incomming are times. The AND box is plugge to a TRUE/FALSE case structure.

I don't understand the error. The 2 datas are the same type, one is connected, the other is not, why ?

Can I do this an other way ?

Thank you.

Benjamin.

Hello Benjamin,

I'm not 100% sure what your trying to do. If you want to AND the two results of these equals/not equals as true/false values, you can use the 'convert from dynamic data type' vi, (on the express palette and signal manipulation, and convert these to boolean values. Then the AND function will work as expected.

I hope this helps, if you need more info, then just post back.
