ProzessFeldtreiber

ProzessFeldtreiber is a software component used in distributed automation and data-processing systems to provide standardized access to process fields via device drivers. It serves as an adapter that translates between high-level process data definitions and the concrete communication protocols used by sensors, actuators, or external systems. By encapsulating field-level semantics such as data types, units, scaling, and validation, ProzessFeldtreiber allows applications to read and write process data without device-specific logic.

In its function, a ProzessFeldtreiber performs data validation, unit conversion, timestamping, and error handling. It supports buffering and asynchronous I/O to accommodate varying device response times. It implements mapping rules to convert between the process data model and the driver interface, and it can apply transformation rules to normalize data for analytics or control loops.

Architecturally, it typically comprises a field model layer that defines process fields, a transformation and validation layer, and one or more driver adapters or plug-ins that implement device-specific communication. It may run as part of a PLC, a middleware service, or a cloud-based automation platform. Configuration is usually data-driven, enabling dynamic addition or modification of fields and drivers without code changes.

In practice, ProzessFeldtreiber is used in industrial automation, process control, SCADA, and MES integrations to bridge legacy field devices and modern software, providing consistent data access, traceability, and scalability.
