Non-Return

Some assets may be marked as 'non-returns' for specific types of relationship. This is often found in regulators, one-way-valves, signal isolators etc.

Non-return assets prevent property flow, zero-energy checks and isolation checks from proceeding any further up-stream.

Below is an example based on our discussions of Property Flow - in this case, the non-return valve prevents the filter from getting attributes from assets further up the water line.
