PI Viewer

Visualize data from PI Data Archive

Since R2022a

Description

The PI Viewer allows you to graphically search and select tags on an AVEVA^® PI Data Archive, then plot data from those tags.

You can plot and examine the data from the tags over a specified time range

Note

You must install the AF SDK library to connect to a PI server from MATLAB^®. For more information, see AF SDK Overview.

Open the PI Viewer

To open the PI Viewer app, in the MATLAB command line type:

viewer(piClientObj)

where piClientObj is the PI Data Archive client created with the piclient function.

Examples

View Data from PI Data Archive Tags

Create a PI client object and open the PI Viewer for reading tags from the PI Data Archive.

piClientObj = piclient("pi-host-55");
viewer(piClientObj)

Select the tags you want to read from, and click the right-arrow to add them to the right-hand column.

If you want to limit the date range, click the Start Date field and End Date field. A calendar pops up for you to select the start and stop dates.

Select the type of graphs you want to view:

• Click to plot all data points on a common time axis.

• Click to generate a matrix of plots, displaying histograms and scatter plots by data groups, in a manner similar to the gplotmatrix function.

  The PI Viewer display might look something like this:
