To OPC properties, yes, but be aware of the issue of handling of OPC Quality.
Normally, you would like to present bad quality, e.g. with an error indication control (typically a red slash or cross) - this is built into most standard graphic controls. By tying in the #DataQuality sub property of a PropertyRef, the element should present data quality issues by itself.
Just hit pound (#) when having selected a PropertyRef and you will be presented with a list of sub properties.
You can assign property references to expression variables, just be aware of that Bad Quality will set value = 0 in most cases and that you must handle it by having another expression with the quality.
