OEE (Overall Equipment Effectiveness) User Guide

Tamaki MES tracks Overall Equipment Effectiveness by binding a location's PLC tags to an OEE model, recording its states and modes over time, and calculating the Availability, Performance, and Quality that make up OEE. Operators review and reason-code stoppages, and dashboards turn the collected data into live and historical insight.

This guide is organized around the OEE section of the MES:

• Terms and Definitions - the OEE concepts and vocabulary used throughout this guide.
• OEE Configuration - set up OEE tracking for a location:
  • OEE Configuration - the per-location provider settings.
  • States - the operational states a location can be in.
  • Modes - the operating modes a location can be in.
  • Alarms - the Ignition alarms watched for a location.
  • Downtime Reasons - the hierarchical downtime reason tree.
  • Calculation Config - pre-computed OEE roll-ups.
• Downtime Entry - review, reason-code, acknowledge, and split downtime events.
• Unit Dashboard - monitor a single unit's OEE, timelines, and losses.
• OEE Mode Records - review and adjust a location's mode history.
• Line Dashboards - monitor OEE across a production line.
