Hello All,

I am trying to move value of 1 tag to another tag's eng low or high. I tried bunch of syntax but no luck, I am sure some of you might have done it with proper syntax.

You cannot. The documentation describes how `engLow` and `engHigh` can be bound to UI components to control data entry operations. You cannot bind the other direction.

You **must** use a change event script on the source tag to write into the target tag's properties.
