Stopping a buffered AO channel by a analog trigger point

[p901]

What I need to do is stopping an buffered AO instantly when I receive a limit from a transducer.
The problem is when I tried writing zeros to Ao Write When a limit occures that there was a few seconds laps before the output channel went to zero. I would like to see at max. 200mS for this to happen.
Should I just clear the channel that a limit has occured and write a zero to AO Single Update to solve this problem or is there another method to stop generation with AO Write.
I have a PCI 6071 and use both analog output channels for outputting buffered generation. One cahnnel is configured as AO group 0 and the other as AO group.
The program is written using Labview 6i


Thanks

Hello;

Onw thing you can do is to configure the Labview shipping example that does triggered Analog Output, to pause while gate is TTL high, at the "trigger or gate condition" input. Also, you need to make sure that the external TTL signal that comes from the sensor, stays high state so the Analog Output will be paused.

Hope this helps.
