Classification lookup list

A classification enables you to predefine the categories of causes for Downtime events or Energy, so that the user can select from a list. This promotes consistency across the data set and better analysis.
After you define a classification, you can make this classification available at certain locations in the hierarchy. Operators can select the classification for a Downtime or Energy event. A classification can be used individually, or as part of a relationship matrix.
When you classify different types of Downtime or Energy events into what is planned and unplanned, you can undertake an informed analysis of events within your process.
Some typical classifications that might be used in a plant hierarchy are for things such as planned downtime, unplanned downtime, or production loss. After you define a classification, the classification can be made available at locations in the hierarchy for operators to select for events that occur at that location.
Tip: You can use Lookup lists to populate menu options that appear as drop-down menu items in the Details dialog box.
Examples of classifications
The Classification list is typically a short list, and is associated with cause codes in the relationship matrix for each equipment type.
The examples of Downtime classifications are:
-
Breakdown, for example, equipment malfunction.
-
Operational delay, for example, raw materials not available, but equipment is healthy.
-
Planned maintenance
Different companies have different definitions for similar classifications. AVEVA™ Production Management enables you to use the same name as the standard for your company, rather than defining these for you. For example, Breakdown could also be called Equipment Malfunction, or Process Stoppage could also be called Unplanned Stoppage.

Time usage model
We recommend that you create a model of time-usage that enables you to define the appropriate classifications for your organization along with the terms to use to name these classifications as shown in the following example.
In this basic model, the classifications are: Planned maintenance, Breakdown stoppages, and Operational stoppages.
