Analog Output in DAQ

[charupraba]

Hi all,

when we write any Value in the Analog Channel it will retain in that Value even if VI is Exit.

here I need to know the Value of the Analog Output Channel at any instant.

Is there any Property Node to get access to it?

Thanks

You might consider saving the value that you output in a Global variable. That would save it after the VI that creates it terminates. Also make it available to any VI in your total implementation.

It is true that many programmers have a dislike for using Global variables, often born out of ugly experiences in multiple-programmer situations. But, in LV, they are a handy tool, especially since you can have more than one named Global variable set, and thus partition your Globals between users. You can also partition shared values among functions, such as output values, control equation constants, etc.

Hi

Thanks for ur reply..

actually how we handled it was we read the value of the Physical channel whose device name and port no must be known to get the value of the Analog Output at any instant..
