Configure ad hoc displays

The Data Items parameter lets you designate the path on the PI Vision AF server to the data items that you want shown, regardless of the current context. The number of additional data items that you specify here has no effect on, and is not constrained by the number context items shown, as defined by the Max Context Data Items to Show property.

You can find the path to the data item by navigating to the asset in the PI System Explorer. Then, copy the path from the Settings pane.

Use the following format to designate data items from an AF Server for display in the PI Vision OMI app:

\\AFServerName\DatabaseName\ParentElement\ChildElement|ChildAttribute

To select an item from a PI Data Archiver server, use the following format:

\\ArchiveServerName\TagName

Use the full URI of the asset or attribute. For example, to plot all attributes of an asset at run time, provide the URI of the asset, as shown in following example:

\\AFServer1\pumpcbm\pump station\plant

To specify a particular attribute of an asset to display, append the attribute name to the asset name, using the pipe symbol as separator between asset name and attribute:

\\AFServer1\pumpcbm\pump station\plant|bearing temperature

To specify multiple attributes, use a semicolon as the separator between attributes. You must provide the full asset name for each attribute specified, even if all the attributes belong to the same asset.

\\AFServer1\pumpcbm\pump station\plant|bearing temperature; \\AFServer1\pumpcbm\pump station\plant|pump\flow rate; \\AFServer1\pumpcbm\pump station\plant|pump speed

Note: Ad hoc displays can be configured to show show the status of different assets as you navigate around your system, via the Follow Current Context property. See Contextualized ad hoc displaysfor more information.
