Modify Equipment IDs

The Equipment database is created in your engineering analysis application; this is not an ArcFM or Network Adapter database. This database holds each type of feature that may exist in your GIS geometric network and participates in engineering analysis in your engineering analysis engine. Features in the geodatabase map to the corresponding types in the Equipment database. This database acts as a look-up table for features in the geodatabase.

Geodatabase features are mapped to the Equipment database using an Equipment ID. This value is a unique identifier for the type of equipment (not the specific feature).

Determining Equipment ID

A single piece of equipment has two different types of attributes: settings and specifications. There are the attributes - or settings - whose values may change given the situation. For example, a fuse's Phase Designation may change (A, B, C). A piece of equipment may also have attributes whose values do not change - or specifications. For example, this same fuse has electrical specifications defined by the model and manufacturer (e.g., rated voltage, continuous current rating).

Generally, specifications are stored in the Equipment database in the engineering analysis engine. Specifications are not usually stored in the GIS because storing the identical specifications for every feature in the geometric network would be redundant. The feature specific attributes (or settings) are stored in the GIS and the Equipment ID is used to map the features to their corresponding types in the Equipment database.

The Implementation component provides a link to equipment data by assigning an Equipment ID attribute to each feature in the XML export. You may determine how the Equipment ID looks (i.e., which attribute values comprise it).

Assign Equipment ID

Once you have determined how your Equipment IDs will look, they must be assigned to the corresponding features in the geodatabase. While each Equipment ID will exist only once in the Equipment database, a single Equipment ID may be assigned to multiple features in the geodatabase (one to many relationship). There are a few different ways to assign Equipment IDs to features in the geodatabase.

Assign Equipment IDs programmatically
Create an attribute on each feature class and manually populate it on each feature with an Equipment ID
Create an attribute on each feature class and populate it on each feature using autoupdaters

NOTE: The Equipment ID field MUST be included in the Minerville or MultiSpeak-Minerville XML.
