ok I want to move the value of a tag at a certain time into another tag. I have the time portion figured out but not sure how to write the expression. any help would be appreciated.
oldTag = system.tag.read('ZOld Tag') system.tag.write('ZNew Tag', oldTag)
Just to clarify, what diat150 showing is a script.
There is scripting and there is expression language.
A quick overview can be found here in the manual.
Personally, I prefer using a transaction group for scheduled items, but there are plenty of way to go about it.
