Forcibly read data

[ASCE_33]

Hello guys,

How to  forcibly read samples from Alchannel objects in a task before trigger signal comes?

Thanks..

Did you figure this out?  When you mention forcing a read do you mean just performing a read?   I haven't worked with triggers before but I would suspect you could set your trigger for a certain set of criteria and still perform a read of all the AI channels.  You would want to put some protection around your code to make sure your trigger even can't occur during a manual read but that would just be some basic source code I think.

Hi ASCE_33,

If you use AI channels of a Scope, data will be recorded before trigger.

If you use a DAQ module, I’m afraid it’s unable to read data before trigger coming.
