I want to write a value of a Numeric Text Field or a Numeric Label to a OPC tag. I can be a Memory tag. Beacause that Value of the tag do I want to use in a other screen.  
But I do not know how to create that.

When you set your property binding on the Numeric or Text Field, just check on the Bidirectional option…
