The library includes functions to navigate and extract specific values from a JSON object without deserializing the whole object. For example, $.production.line2.temperature can be read directly.
Traditionally, Beckhoff PLCs communicated via TwinCAT ADS (Automation Device Specification). While incredibly fast for real-time control loops, ADS is binary, proprietary, and difficult to query from standard web browsers or cloud services. beckhoff json
With the introduction of TwinCAT/BSD (Beckhoff’s operating system based on FreeBSD), Beckhoff controllers can run Docker containers. This opens new possibilities: The library includes functions to navigate and extract
JSON is text-based and verbose. Binary protocols (ADS, OPC UA) are 5-10x faster. While incredibly fast for real-time control loops, ADS
Beckhoff JSON offers a powerful and flexible way to exchange data in industrial automation applications. By leveraging the advantages of JSON, Beckhoff's automation products, such as TwinCAT 3, can efficiently communicate with other components of the control system, enabling a wide range of applications, from smart manufacturing to industrial IoT and condition monitoring. As the industrial automation landscape continues to evolve, the use of JSON is likely to play an increasingly important role in enabling seamless communication and data exchange between different systems and devices.
Using the advanced library, you can serialize this in one line: Serialize(beltInstance, jsonString);
