The PI-BatchView ActiveX control is a query dialog that lets the user search the PI batch database and Unit/Alias table. This control can be used in any 32-bit program that can contain ActiveX Controls such as Microsoft Access 95 or Microsoft Visual Basic 4.0. The user specifies the batches of interest. Information in the query may specify a particular unit in which a product ran, specific products, or perhaps the date when the batches ran. PI-BatchView allows the user to view batch summary information such as start time, end time, and duration of the batch. Phase changes of a batch will be noted by a "mark" when trended.
Batch Trend Add-In
The PI-BatchView Add-In for PI-ProcessBook allows users to conveniently display batch-related data in a PI-ProcessBook workbook. The user can trend variables by alias, set trend time bases relative to start of batch or phase, and compare multiple batches. Identical products may have batch cycle times of varying lengths depending on hold conditions and when users views several batch runs of the same product, the "knees" of the trend curves may not line up because of these varying times batch run times. PI-BatchView allows a user to select each knee and align the pens to view the information in that context.
Microsoft Excel Add-In
The Microsoft Excel Add-In for PI-DataLink consists of a set of dialogs and functions that let the user incorporate batch data in a spreadsheet. It supports 16-bit as well as 32-bit environments through the use of an ActiveX Automation server that simulates the PI-BatchView ActiveX control.
Alias Function for PI-BatchView
PI-BatchView supports an alias function that permits the user to specify, for example, "temperature" when defining a batch trend. PI then resolves the alias for "temperature" for the batch that is selected. PI maps the alias to the corresponding PI tag, evaluates the time period, and retrieves the data according to the batch cycle time period. To use this feature the user creates one display for multiple or similar pieces of equipment.
