Hi, is there a way to reset a value of an Analog tag on page entry?
Thanks in advance.

This tag is mapped to a DropList object on the page, to track the selection.

Looking for a way to set the value of this tag to Zero so that on page entry the DropList shows a blank selection, otherwise it stays on the last selected item.

For that, you'll want to use the set() function. See below:

Thanks a lot Dave.

That did it.

On the page script I now have:

Scope(\VTSDB,"GUID of the tag", TRUE)\Set(0);

And when the page opens up, it sets the value of the tag to zero. Success.

It looks like the set(0) is executed while the page is open, so the tag value always stays as Zero.

Is there a way to get this executed once, when the page is opened only?

You should put it in the following:

  If Watch(1);
  [
    ...; 
  ]

This script will be executed once only, and then the function will be reset to false (i.e. the script will not again execute unless the module, or containing state, is stopped and restarted).

That did the trick. Thanks a lot!

I'm glad that you got this figured out. Event driven languages can be a bit weird but are also super efficient.
