Property Definitions

AVEVA Instrumentation supports user-defined properties for use when creating instrument datasheets and when defining instruments, process plant equipment, and process lines. These properties enable users to create meaningful attribute names for data that has no other logical property or field within the project database. Properties can belong to one of two Property Type groups (Class Types):

• Instrument Properties

  • Instrument data

  • Instrument specific process data

• Process Properties

  • Common Process object properties

  • Process Equipment specific properties

  • Process Line specific properties

Once created, a new property can be assigned to a catalogue datasheet template. When datasheets based on that catalogue datasheet template are created, data can be assigned to that property on the datasheet which then updates the database.

New properties can be displayed in the following grids within the Process Engineer module:

• Process Data

• Process Equipment

• Process Lines

New properties will also be displayed in the Process Data grid and on the Properties tab of the Instrument and Catalogue Instrument details windows in Instrument Engineer, as well as the Properties tab of the Process Equipment and Process Line details window in Process Engineer, thus enabling data to assigned to that property for an instrument, item of plant equipment, or process line.

It can also be added to data grids using the List Manager facility and will be available as a DataLink to be assigned to drawings in the Designer module. For more information, refer to Common Functionality of AVEVA Instrumentation.

Note: If the user has a catalogue datasheet template open at the same time as creating a new field, the new field does not display until the datasheet is closed and then re-opened.

View Property Definitions

1. To display the Property Definitions window, select Setup > Property Definitions from the Project tab:

   

2. The window lists the existing properties. Two classes of properties may be listed: Process and Instrument. Select the required class from the Class Type dropdown list.

3. The Process property class is sub-divided into three object types: Common, Process Equipment, and Process Lines. Select the required object type from the Object Type list.

   A number of properties are supplied with the product. Note that the names of these properties are all suffixed as follows:

   • pc prefix indicates a common property

   • pl prefix indicates a process line property

   • pe prefix indicates an equipment property

   • psz prefix indicates a property used by the sizing calculations

   Properties used by the sizing calculations are found in the list of all three object types. Note that these are displayed with a grey background. This indicates that they cannot be amended or deleted.
