Attributes

Attribute Required Description Value Options

type

No

The input data item type that matches the input data category type defined for the category attribute of InputDataImport element.

String (in quotes). The value of the type attribute must match a type value previously defined in the ELF device configuration. Examples of a data item type for the input data category “Weather” include “Temperature” or “Wind Speed.”

units

No

The units of the input data item type.

String (in quotes). The value of the units attribute corresponds to one of the valid units or a description for the Primary Units field in the PNT record, or it can also be a string that does not match any of CygNet’s recognized units. See PNT Engineering Units.

An example of the units for a data item type of “Temperature” might be “F” or for “Wind Speed” the units could be “mi/hr.”

Note: The predefined units for the PNT record have both an abbreviation and a description. The abbreviation is what is stored in the record, and that has a character limit of 8 characters. In the XML file, the units attribute value can refer either to the unit abbreviation (8 characters max) or to the description (no character limit). If you are specifying a string that does not match any of CygNet’s recognized units the ELF import will accept the units and copy them to the record. In this case the character limit is 8 characters for units not already defined.

Example

<ItemDataRecord type="AVWSPD" units="mi/hr">

<ItemDataValue start_time="2009-03-12T08:00:00.000-08:00" end_time="2009-03-12T09:00:00.000-08:00">23.234</ItemDataValue>

<ItemDataValue start_time="2009-03-12T09:00:00.000-08:00" end_time="2009-03-12T10:00:00.000-08:00">25.456</ItemDataValue>

</ItemDataRecord>
