Basics of OEE Data Capture

Determining Overall Equipment Effectiveness relies on precise mathematical models and standardized calculation methods, encompassing three core components. The technical implementation of data capture for these components is critical for the accuracy and reliability of OEE monitoring.

Graphical representation of the OEE calculation formula, showing the three factors—Availability, Performance, and Quality—multiplied to yield the OEE value. OEE Core Formula Availability Performance Quality × × OEE = Availability × Performance × Quality
Figure 1: The OEE core formula visualizes the multiplicative combination of the three factors: Availability, Performance, and Quality

1. Availability

The availability of a system is defined as the ratio between planned production time and actual operating time, expressed by the formula:

Availability = Operating Time / Planned Production Time = (Planned Production Time - Downtime) / Planned Production Time

Capture Parameters

To accurately calculate availability, the following technical parameters must be captured:

  • Planned Production Time: Defined by production planning, shift models, and working time regulations
  • Downtime: Time periods when the system is not operating despite planned production
  • Setup Times: Time intervals for product changes, tool changes, and setup processes
  • Downtime Causes: Categorized cause codes per ISO 22400 or company-specific catalogs
  • Micro-Downtimes: Short interruptions below a defined threshold (typically 3-5 minutes)

Technical Detection Methods

Capturing system availability can be achieved through various technical methods:

  • Direct Signal Detection: Capture of PLC signals such as "System in Automatic," "Emergency Stop," or "Fault Active"
    • Implementation Example: Connection to potential-free contacts with 24V signal level and optocouplers for galvanic isolation
    • Sampling Rate from: 10ms for precise detection of short downtimes
  • Operating Time Monitoring: Measurement of drive components via current consumption or speed sensors
    • Technical Parameters: 4-20 mA current measurement with converters, frequency inputs for speed detection
    • Threshold Definition: Configurable limits to distinguish between idle and production
  • Advanced State Models: Use of multi-level state models beyond simple run/stop detection

OEE Monitoring: From Data to Insights

Mere data capture does not yet create value. Only through systematic monitoring and meaningful visualization do data become a valuable basis for decision-making.

Real-Time Monitoring

Modern OEE monitoring systems provide real-time insights into production status:

  • Live Status Monitoring: Current operating states of all systems
  • Performance Tracking: Continuous monitoring of OEE components
  • Alert Systems: Automatic notifications for deviations or faults

These real-time functions enable quick responses to issues, preventing prolonged productivity losses.

Historical Analyses

In addition to real-time monitoring, analyzing historical data is crucial for continuous improvements:

  • Trend Analyses: Long-term development of OEE and its components
  • Loss Analyses: Identification and quantification of the largest loss factors
  • Comparative Analyses: Benchmarking between systems, shifts, or sites

These analyses enable the identification of systematic issues and the derivation of targeted measures for OEE improvement.

Visualization: OEE Dashboards

The visual presentation of OEE data plays a central role in its usability:

Typical Dashboard Elements

  • OEE Gauges: Tachometer-like displays for overall value and components
  • Time Series Charts: Visualization of OEE trends over time
  • Pareto Charts: Prioritized display of loss causes
  • Heatmaps: Color-coded representation of problem areas
  • Production Calendar: Overview of OEE values by days or shifts

Application-Specific Dashboards

Different dashboard variants are needed depending on the target audience and use case:

  • Shopfloor Dashboards: Large display boards focusing on current performance
  • Management Dashboards: Summary views focusing on KPIs
  • Analysis Dashboards: Detailed evaluations for production experts
  • Mobile Dashboards: Optimized display for smartphones and tablets

The proper design of these dashboards is critical for the effective use of OEE data across various business areas.

Modern OEE Software: From On-Premises to Cloud-Native

The evolution of OEE software has paralleled the broader development of IT landscapes, transitioning from traditional on-premises systems to advanced cloud-native solutions for enhanced digital manufacturing efficiency.

Legacy Systems and On-Premises Solutions

Traditional OEE systems were often implemented as on-premises solutions:

  • Local Installation: Software operated on company-owned servers
  • High Initial Costs: Significant investments in hardware, licenses, and implementation
  • Complex Updates: Time-consuming update processes with potential downtimes
  • Limited Scalability: Capacity expansions require additional hardware
  • Isolated Data Silos: Limited options for cross-site data consolidation

While these systems offer high control over IT infrastructure, they pose significant drawbacks in agility, scalability, and cost structure.

Cloud-Native MES Solutions

The latest generation of Manufacturing Execution System (MES) software leverages cloud-based technologies and follows the Software-as-a-Service (SaaS) model:

  • No Local Infrastructure: Operated in high-availability data centers
