Plant Direct iT is neither a SCADA nor a HMI nor a DCS. Plant Direct iT is an open, PLC-based process control system with an extensive set of technical and technological automation classes.

The range of technical basic classes includes a basically equipment-neutral functionality, e.g. valves, drives, measured values and controllers, and highly-qualified equipment-specific functions, e.g. for parameterising and controlling frequency converters.

The technological classes, on the other hand, provide the functionality for mapping process sequences. The main representatives of this group are phase controllers, the Object Control Matrix (OCM) and the logic class. Using these classes, the parameters of the process functionality become fully configurable – from the valve to the sequence control.

Plant Direct iT supports parameter-based process control. This ensures that previously parameterised sequences can be varied easily by dynamically combining them with various parameter sets, i.e. for considering different operating modes of a plant or products to be processed.

Another special feature is Plant Direct iT Visu-Recorder, which can be optionally installed. This application enables the retroactive monitoring of previous process sequences via the standard user interface and their direct output via the process visualisation, similar to a VCR. This unique feature facilitates the retroactive analysis of errors in the process sequence.

The client/server architecture, the intuitive user interface and the object-related class concept turn Plant Direct iT into a future-proof alternative to traditionally programmed controls with higher-order visualisation.
