Label Validation against Specifications

Label validation against specifications is used to control which symbols can be inserted into pipes based on the specification of those pipes.

For example, it may be specified that Ball Valve symbols may only be inserted into pipes with a specification of AAA3, and an inlet bore size of 20 and an outlet bore size of 20. The project may be set either to prevent the insertion of symbols into pipes that are not of the correct specification, or to display such symbols in a specified colour.

Multiple combinations of pipe specs and sizes may be specified as compatible with the insertion of a symbol. If no specs or sizes are specified for a symbol, insertion of this symbol is unrestricted.

Spec/size insertion restrictions may be set up for Valves, Instrument Valves and Reducers.

Currently, only restrictions for 2-way symbols may be specified, but not symbols inserted at pipe junctions such as 3-way and 4-way valves.

Label validation against specifications is set up using the Spec Driven Configuration Category of the AVEVA P&ID Project Administration program.

Note: Changes to drawings resulting from changes to Spec Driven settings are not automatically implemented when project drawings are loaded. The user must trigger these changes "manually" in each drawing after it has loaded. Refer to Update Spec Driven Data.
