OEE Efficiency Display

1. What is OEE?

OEE (Overall Equipment Effectiveness) is a standard measure used to evaluate manufacturing equipment and production efficiency. It combines Availability, Performance, and Quality into a single percentage to help identify production losses and improvement opportunities.

2. How is OEE calculated?

OEE is calculated using three key factors: Availability × Performance × Quality.

• Availability measures how much planned production time the equipment is actually running.
• Performance measures whether the equipment is operating at its expected production speed.
• Quality measures the proportion of good products produced compared with total production.

The OEE display can calculate and present these values in real time based on the data received from the production system.

3. What are the input sources?

The OEE system can receive production data from sources such as PLC signals, machine sensors, production counters, SCADA systems, and other equipment monitoring systems. The appropriate input method depends on your machine and production setup.

4. Can it connect to PLC or SCADA?

Yes. The OEE display can be integrated with PLC and SCADA systems to receive production and machine-status data. Depending on the application, communication can be provided through RS485, Modbus RTU, Ethernet, digital signals, or other suitable interfaces.

5. Can historical data be recorded?

Yes, historical OEE data can be recorded when the display is integrated with a suitable data logging, SCADA, database, or monitoring system. This allows production teams to review previous performance, identify trends, and analyze recurring production losses.
