This driver monitors an accumulating field value, for example a energy (kWh) or volume register that continuously counts up. The driver captures the field value at a given interval (hourly, daily etc..) and computes the difference between the start and end of the interval. Current value and the four previous are provided.

Name - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default “Field” name (if added to “Fields”)

Active Check box - Check this box and “Save changes” to run the driver. The driver program can be suspended by unchecking the box and clicking on “Save changes”.

User Notes - This space can be used to store information specific to the device and your application, such as: the asset being monitored, the purpose of monitoring, etc.

eze System Notes - In this space we provide a description of the driver's function.

Accumulator Field - Use the drop-down menu to select the Field to be monitored.

Interval - Use the drop-down menu to select the differential's interval. Options are; Hourly, Daily, Weekly, Monthly or Yearly.

Driver info - Typically this is the name from the program file

Driver updated/version - Date loaded or updated and the version of the driver

Battery & Signal - Signal indicates the progress through the script. If driver fails to operate, signal number indicates progress

Driver status - Color and text of status bubbles give a quick visual reference of Communication, Operation, and Application

Communication - Com count indicates number of successful and unsuccessful data packets received

1. Accumulator value - Current value in selected Field.
2. Current interval partial diff - Differential between value at beginning of interval and current value.
3. Previous interval diff - Most recent interval differential captured. Daily example: Yesterday's differential
4. 2nd interval diff - Second most recent interval differential captured.
5. 3rd interval diff - Third most recent interval differential captured.
6. 4th interval diff - Fourth most recent interval differential captured.
7. Value at start of current interval - Speed of travel is given as meters per second.
8. Interval identifier - Current interval step, out of a complete cycle (expressed as a number). See table below
