PI Vision Custom Symbol Issues

Hi There,

 

Few question while developing a custom symbol:

Is it mandatory to have an 'dataupdate' function?

Is there a way to control the time frequency to call the  'dataupdate'; I believe the default is 5 seconds?

 

If the AF Attribute that I drag while selecting the CS contains non-PI point data, how do I fetch this in the  'dataupdate' function?

 

Emad.
