Configuring the external system UOM map code table

From the External system UOM map code table code table, map the unit of measure used in OpenWay to IEE.

OpenWay stores energy reads as quantity values and these values must be converted to energy reads that IEE can interpret and process. You must map the units of measure provided by OpenWay to units required for storage by IEE and scale the energy units correctly. For example, a channel of watt hour delivered data can be identified as "Whd" or "Wh d" in the OpenWay message, while IEE can store the data with a unit of measure shortcut like KWH_DEL. As a result, when the IEE DeviceComm Service Interface receives a reading message from OpenWay, the quantity identifier provided by OpenWay (Wh d, for example) is mapped to an IEE known unit. This mapping accomplishes the following:

• It identifies the scaling factor that must be applied to the OpenWay units to scale them to the correct IEE unit. For example, to scale Wh values to kWh values, the Wh value must be divided by 1,000.

• It identifies the correct service point channel against which the scaled reading is stored. OpenWay does not identify meter channels by a numeric ID. Instead, the UOM (or quantity identifier) is used by OpenWay to uniquely identify a given channel of data.

The OpenWay energy reads are defined in the OpenWay Collection Engine. For more information, see "Meter Management" in the OpenWay System Administrators Guide.
