Overall Equipment Effectiveness (OEE) Configuration Overview
Plant Applications' OEE functionality is built upon the core Availability X Performance X Quality formula. Once configured, Plant Applications captures and categorizes data from your process, then performs calculations to derive availability, performance, and quality rates. When multiplied together, these produce the OEE rate. For detailed information, see OEE Terminology and Calculations.
Requirements for OEE
In order to use Plant Applications' built-in OEE functionality:
-
You must have purchased the Proficy Server with the Efficiency module.
-
For the OEE by Unit Web Part and OEE Summary report, the Proficy Dashboard and Proficy Web Reports modules are required.
-
In cases where you wish to analyze a unit or line that is event based (batch process) and not time based (continuous process), you may require the Quality module. In most cases, however, OEE is calculated for time-based operations such as packaging lines, and this module is not required.
Configuration
Preparing to measure OEE involves the coordination of many areas in Plant Applications, and requires considerable time and planning. Essentially, however, to configure OEE in you will:
-
On a unit-by-unit or line-by-line basis—depending on what entity you are measuring—determine your equipment's ideal performance capabilities by product, and set these ideal capabilities as specification targets.
-
Configure a variety of historian tags and other data inputs from your process control system to capture downtime, waste, and production events.
-
Ensure that Plant Applications is configured to model the production process (i.e., in the Plant Model), and capture and categorize the data in order to facilitate the OEE Production Metric calculation.
-
Configure displays for manual editing of Downtime and Waste as required, and for alarming on availability, performance, quality and OEE if alarms are configured.
-
Configure reports, such as the built-in OEE Summary Report and the OEE by Unit Web Part, in order to actually view OEE data and drill down into your operations.
Following are the areas involved in configuring OEE in Plant Applications. Each linked topic provides information particular to OEE, and where necessary points you to other sections of Plant Applications Help for further information.
