Driver Communication Summary Report

A driver communication summary report contains three groups of information, summarizing a driver’s activity for a specified time period.

When you select Driver Communication Summary Report in the Report Types drop-down list, the Types drop-down list filters to display Drivers.

In addition to the report header identifying the report type and duration set for the report, the driver communication summary report includes:

Driver quality information:

Quality is calculated based on a weighted time interval. Communications closer to the present have more importance than those further in the past.  The quality is a running analog value that can be trended on the historical data viewer. Sudden dips in the graph indicate periods where problems occurred. By comparing the %start quality to the %end quality for a given time frame, you can determine whether events that occurred during that time improved or damaged communication quality.

The following columns relate to driver quality information:

•    The tag name for each driver tag included in the report.

•    The % average quality of data for each driver within the specified time period.

•    The % minimum quality of data for each driver within the specified time period.

•    The % maximum quality of data for each driver within the specified time period.

•    The % start quality of data for each driver within the specified time period.

•    The % end quality of data for each driver within the specified time period.

Communication timing information:

These three values provide an indication of communications lag time and can be used to identify bandwidth issues that may be present.

•    The average Response time (i.e. the time between successive messages) for each driver within the specified time period.

•    The minimum Response time for each driver within the specified time period.

•    The maximum Response time for each driver within the specified time period.

Communication count information:

These four values are actual counts recorded during the time frame.  Unlike the quality information, these values ignore communications that occurred before the time frame.

•    The number of failed data transmissions for each driver within the specified time period.

•    The number of failed reattempts at data transmissions for each driver within the specified time period.

•    The number of successful attempts at data transmissions for each driver within the specified time period.

•    The % success for each driver within the specified time period. This is calculated as: (success counts) / (failed counts + success counts).  The counts begin at the start of the given time frame, thus this value can be useful for hour to hour or day to day comparisons.
