The integration of Manufacturing Execution Systems (MES) is a crucial step for manufacturing companies that want to digitize and optimize their production processes.
In this comprehensive guide, you'll learn everything about MES integration - from the basics to proven practices and common challenges.
What is MES Integration?
MES integration refers to the process of connecting a Manufacturing Execution System with other enterprise systems and production facilities. Various data sources, systems, and technologies are brought together into a unified production platform.
The key integration goals:
- Real-time data flow between all production systems
- Automated data collection from machines and equipment
- Seamless communication between shopfloor and ERP systems
- Unified data foundation for better decision-making
- Process optimization through connected systems

Why is MES Integration Important?
The integration of MES systems brings numerous benefits for manufacturing companies:
1. Improved Production Transparency
Through integration, you get real-time insights into all production processes. OEE metrics, machine status, and production progress are centrally captured and visualized.
2. Reduced Data Silos
Integration eliminates isolated system landscapes and creates a continuous flow of information from the shopfloor to management.
3. Automated Processes
Manual data entry is minimized, which reduces errors and increases efficiency.
4. Better Compliance
Integrated systems simplify adherence to quality standards and regulatory requirements.
MES Integration Architecture: The 5 Layers
A successful MES integration typically follows a 5-layer architecture:
Layer 1: Production Equipment
- Machines and equipment
- Sensors and actuators
- Robotics and automation systems
Layer 2: Connectivity and Data Collection
- IoT Edge Devices for automatic data collection
- OPC-UA Gateways for process data
- Digital signal acquisition for machine status
Layer 3: Manufacturing Execution System
- Production planning and control
- Quality management
- Material tracking
- Personnel management
Layer 4: Enterprise Integration
- ERP connectivity for order and material data
- WMS integration for warehouse management
- QMS connection for quality data
Layer 5: Business Intelligence
- Dashboards and reporting
- KPI monitoring
- Data analysis and trends
Integration Methods for MES Systems
1. REST-API Integration
Modern MES systems offer REST APIs for connecting external systems:
GET /api/production/orders
POST /api/machines/status
PUT /api/quality/measurements
Advantages:
- Standardized interfaces
- Easy implementation
- Scalable architecture
2. OPC-UA Connectivity
For connecting production equipment, OPC-UA has become the standard:
- Real-time data from PLC systems
- Process values and alarms
- Bidirectional communication
3. Database Integration
Direct database connectivity for legacy systems:
- ETL processes for data transfer
- Data harmonization between systems
- Batch processing for large data volumes
4. Message Queue Integration
For asynchronous data transfer:
- MQTT for IoT devices
- Apache Kafka for stream processing
- RabbitMQ for reliable message transmission
