Overview

Value+ displays a PI Point or AF attribute value and adds configurable tooltips, copy-to-clipboard support, multiline text, and floating ad-hoc trends to the standard PI Vision value experience.

When to use it

Use Value+ when you need to:

  • Display a current or time-specific value with additional context.
  • Open a floating trend without leaving the display.
  • Copy the resolved PI Point or attribute label.
  • Present long string values across several lines.

Use a full trend symbol when the historical pattern is the primary information rather than a drill-in action.

Before you begin

  • Prepare one PI Point or AF attribute.
  • Confirm that the data source returns the data type expected by the display.
  • Ask an administrator whether global Value+ defaults replace or override per-symbol behavior when an expected option is unavailable.

Add and set up the symbol

  1. Select Value Plus in the PI Vision symbol gallery.
  2. Drag a PI Point or AF attribute onto the display.
  3. Right-click the symbol and select Configure.
  4. Select the displayed timestamp, visibility options, and tooltip content.
  5. Enable the copy-label or ad-hoc trend actions when operators need them.

Use the symbol

Hover over Value+ to display the configured label and PI Point attributes. When enabled, select the copy action to place the resolved label on the clipboard.

Select the ad-hoc trend action to open a floating trend for the current data source. If a floating trend is already open, use the additional action to add the value as another trace or open a separate trend window.

The floating trend can be moved and resized and remains above the display while it is open.

Configure the symbol

Data retrieval

  • Time: Uses the display end time, display start time, or a custom PI Time expression such as t or *-1d.
  • Offset: Applies an optional offset to the selected timestamp.
  • Exact: Requires a recorded value at the exact timestamp. Disable it to use the most recent value before that time.

Timestamp visibility

Configure the date and time components displayed with the value.

Value+ timestamp formatting

Multiline text

String data sources support two multiline modes:

  • Split: Breaks text at a configured delimiter such as \n.
  • Wrap: Starts a new line after the configured maximum number of characters.

Copy label

Enable Copy Label to show a clipboard action for the currently resolved label.

Tooltip

  • Displayed label: Shows the PI Point name, path, or another supported label form.
  • Point attributes: Adds selected PI Point attributes such as instrumenttag, datasecurity, or pointsource.
  • Style: Sets the tooltip font size, background color, and text color.
  • Ad-hoc chart: Shows or hides the floating-trend action.

Global Value+ defaults are maintained by administrators in the Vision Library+ configuration. See the installation and administration guide for global replacement, tooltip, and copy-label settings.

Troubleshooting and limitations

  • No value appears in Exact mode: Confirm that the archive contains a value at the exact requested timestamp or disable Exact.
  • The ad-hoc trend action is missing: Enable it in the tooltip settings and confirm that it is not disabled globally.
  • Tooltip settings do not match the symbol: Check whether an administrator configured global Value+ defaults.
  • Long text is clipped: Enable Split or Wrap and increase the symbol height.
