Process Data, Equipment and Lines

In AVEVA Instrumentation, there are two methods of recording the details of process data associated with an instrument (for example, for inclusion on instrument datasheets):

• The process data can be recorded against each specific instrument using the Process Data grid.

  In this case, if for example a process value (flow rate) of a line changed, this value must be updated for each and every instrument that is associated with that line.

• Instruments can instead be associated with actual process equipment and process line items in the AVEVA Instrumentation Project Database (see Assign Process Equipment and Process Lines).

These items of equipment and lines have their own specific process and physical properties. If a process value such as flow rate changes, this change is made against the line, not the instruments associated with that line in other words, in one place. All instruments associated with that line that automatically reference this single updated value, thus ensuring data consistency on deliverables such as instrument datasheets.

These items are created and edited in the Instrumentation Process Engineer module, but can be viewed in the Instrumentation Engineer module.
