Move tag value

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 ='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. :slight_smile:

Personally, I prefer using a transaction group for scheduled items, but there are plenty of way to go about it.
