The importance of reliable data in industry<\/h2>\n

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? <\/p>\n

Why traditional solutions fall short<\/h3>\n

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. <\/p>\n

Edge Controllers: the key to local data integrity<\/h2>\n

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. <\/p>\n

How Edge Controllers prevent data loss: Store & Forward<\/h3>\n

One of the most important functions of an edge controller is implementing the Store & Forward<\/strong> mechanism. This involves: <\/p>\n

    \n
  1. Data Storage (Store):<\/strong> 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. <\/li>\n
  2. Data Forwarding (Forward):<\/strong> 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. <\/li>\n<\/ol>\n
