-==== Accumulator Difference driver ====
-=== Description ===
-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.

-==== Settings (center panel) ====
-**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.

-==== Status & Registers (right panel) ====
-=== Device Status ===
-**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
-----
-=== Available registers ===
-  - **Accumulator value -** Current value in selected Field.
-  - **Current interval partial diff -** Differential between value at beginning of interval and current value.
-  **- Previous interval diff -** Differential captured in the most recent interval. Daily example: Yesterday's differential
-  - 2nd interval diff - East-West coordinate
-  - 3rd interval diff - Approximate height relative to sea level, given in meters
-  - 4th interval diff - Expressed as dilution of precision (DOP). In this metric readings of less than 1 are ideal and greater than 20 are poor.
-  - Value at start of current interval - Speed of travel is given as meters per second.
-  - Interval identifier - Interval number, out of a complete interval cycle. **Hourly example:** Hours 0 to 23, **Monthly example:** 1 to 12, **Yearly example:** 2037
