The importance of reliable data in industry
In today’s industrial environments, seamless and reliable data transfer is crucial. From production optimization to real-time monitoring, the quality of your insights depends entirely on the integrity of the data. However, network interruptions, malfunctions, or unexpected peak loads can lead to costly data loss. How do you ensure that data flows securely from the factory floor to the cloud or central databases?
Why traditional solutions fall short
Data is often sent directly from machines (such as PLCs) to a central server. This works as long as the connection is stable. But what happens during a temporary network failure? Without a safety net, the measured values generated during the interruption disappear. This leads to gaps in your historical data, which can hinder analysis and decision-making.
Remote Edge Controller
Edge Controllers: the key to local data integrity
Edge controllers are powerful, compact computers placed directly on the factory floor, close to data-generating devices such as PLCs. They play a crucial role in ensuring data integrity by enabling local intelligence and buffering.
How Edge Controllers prevent data loss: Store & Forward
One of the most important functions of an edge controller is implementing the Store & Forward mechanism. This involves:
- Data Storage (Store): The edge controller receives data from the PLCs via protocols such as OPC UA. If the connection to the central database (SQL, cloud) is lost, the controller stores this data locally. This can be done on internal storage, an SD card, or a built-in database.
- Data Forwarding (Forward): As soon as the connection to the central database is restored, the edge controller forwards the stored data in the correct chronological order. This ensures that no measurement values are missed.
Advantages of Edge Computing for data integrity
- Local buffering: Prevents data loss during network interruptions.
- Real-time processing: Ability to pre-process, filter, or aggregate data locally before it is sent to the cloud.
- Increased reliability: Makes systems less dependent on a continuous, stable cloud or network connection.
- Secure data exchange: Edge devices can act as a secure gateway, featuring built-in security functions.
The role of OPC UA and Edge Controllers
Edge controllers work seamlessly with OPC UA. They can function as an OPC UA client that reads data from machines, and subsequently as an OPC UA server or via other protocols to push the buffered data to the central database.
