What's the different between Meta Data Source and Virtual Data Source?
-
I need to set value of a data point(A) according to calculation on another data point(B).
Should I create A as a Virtual Data Point or a Meta Data Source?
A will be a binary value.
thanks.

You can use either for this purpose but it's probably better to use a Meta Point. Meta Points create a new point base on the script where a Scripting Data Source can set multiple points from within it's script. The other difference is that a Meta Point can be set to run on a context update where the Scripting Data Source will only run on a CRON.

Joel, thanks.
How can I test Meta Data Source in Mango Automation in a free model?
Now I can't find the DS in the free Mango Automation core download.

The Meta Data Source can be used in free mode just like all the other modules. In free mode it will be restricted to 5 data points. If for some reason it's not in your installation you can download and install it from here: http://store.infiniteautomation.com/module/meta

Solved it by your instruction. thanks.
BTW, anybody else who need to do the same thing must pay attention to download right version for your Mango installation.
