The Workflow option enables instrument engineers and process engineers to control the data entry process for instrument tags by specifying when engineering data or process data should be entered for a specific tag. Workflow defines an additional level of access rights for individual instrument tags, determined by the Workflow status of the tags. In this way, an instrument engineer, while working on instrument data for a specific tag, can lock out process engineers from making changes to process data until all the instrument data has been entered.
Example Scenario
The following stages describe a typical Workflow scenario:
-
An instrument engineer creates a new instrument tag and determines whether the tag requires process data. If the instrument tag does require process data, the process data fields of the tag become available to the process engineers for editing.
-
The process engineer, after first accessing the instrument tag for editing of process data, can lock the process data fields against any changes wherever the instrument engineers have access rights.
-
On being released by the process engineer, the instrument engineer can now enter instrument data as required. The instrument engineer can lock the tag against any changes wherever the process engineers have access rights.
