FB Net EIE – FMS Legacy History Data Group

FMS Legacy History Data Group

The "FMS Legacy History Data" (GmrHist) data group is used to send specific historical data to the FMS. Only one instance of an "FMS Legacy History" data group in a device template file is possible. It gets its data from one or more history support data groups.

Support data groups are found in the supportDg section of your sample template. Mapping between "FMS Legacy History" data group elements and FMS Legacy data items is within the histItems section of gmrMaps in the device template file.

Specify date ranges on a per-data group basis within the device editor. For more information, see Selecting Date and Time.

FMS Legacy History Data Group (DataGroup ID) Attributes

The following table represents "FMS Legacy History" data group attributes. All attributes in CygNet templates are case sensitive, but the case sensitivity of attribute values is based on context.

For information about available generic attributes, see DataGroup.

Attribute	Description	Value	Required
ptTime	ptTime is only applicable in Modbus-based FMS Legacy history data groups. It specifies which timestamp to associate with a historical value used in point processing. The FMS Legacy history data group has two timestamps: start time and end time. The time range represents the time span from which an average value is calculated. Value: start: The start time of a time range (for example, 10:00:00). endExclusive: The exclusive end time of a time range (for example, 10:59:59). endInclusive: The inclusive end time of a time range (for example, 11:00:00). Default is start.
