Debugging Options

On the UniInt/Debug page, use the settings in the Debugging Options window to the right to configure debugging options.

• Scan Performance Summary

  When the percentage of scans that a UniInt-based interface performs on-time drops below 95%, UniInt will log performance summaries for each scan class. For information on Performance summaries, see the "Performance points" topic in the PI Universal Interface (UniInt ) User Guide.

  The interface checks whether a performance summary should be logged every interval hours. For example, if Scan Performance Summary is 0.025, the interface will log performance summaries every 90 seconds if the percentage of on-time scans is below 95%.

  The minimum time between summaries is 60 seconds. Setting Scan Performance Summary to 0 disables summaries.

  If the inputs for the interface are unsolicited, then Scan Performance Summary should be set to 0 because performance summaries are meaningless for unsolicited input points. Click Reset to load the default Scan Performance Summary (8) setting to the text box.

  The command-line equivalent for setting this option is /perf or /perf=x.

• Log all values & timestamps for

  If the Log all values & timestamps for check box is selected, the values and time stamps that are received by the interface are also written to the log file.

  Tracing can be enabled for a particular point by specifying a tag name or point ID in the text box provided. The Tag Search button brings up the Tag Search dialog box. This option should be used with caution because specifying this option could cause the log file to become very large.
