Is there a comparison of the various scripting data sources (Meta, Virtual, Scripting) etc. explaining their intended uses/advantages etc.?
For example, I need to create a manual input; I think a Virtual point is what I should be using, but I'd like to know it's indeed what is most effective for that purpose, and why (or why I shouldn't use a Meta, for example).
Also, on a related note, is it possible to use a scripting data source on a schedule (e.g. reset a value every hour) or as an event handler (e.g. when a MODBUS slave disappears, run a script to attempt recovery)?
Thanks in advance,
