Smart Instrumentation does not support retrieving P&ID drawings that have a bidirectional flow. When retrieving P&ID drawings to Smart Instrumentation they must have a flow direction of End 1 Upstream or End 1 Downstream.
When Smart Instrumentation retrieves data from Smart P&ID, it traverses piping connectivity from instruments to detect relationships to process lines and process equipment. Smart Instrumentation has been enhanced to include special cases for relief valves. The following examples describe use cases in which the retrieval creates the process line or process equipment that contains the relief valve, and the relationship between these objects.
