The application logic (control functions) and the required setting and configuration data are processed during engineering and loaded in the corresponding system products, such as Desigo CC or an automation station during commissioning.
This data is arranged according to two criteria:
- Data category
- Data ownership
Data categories: A common method of classifying data in building automation and control systems
Software components which perform a predefined task and have a known interface.
Function blocks, functions, program blocks, compounds, solutions
Values that affect the program elements.
Setpoints, default values, limit values, address settings
Data in the form of defined constants, or data that influences the appearance or operability of the plant.
Description data, templates, profile, metadata
Physical process variables of the plant during operation. History or saved process data are plant data.
Measured values, state variables, calculated values
Data ownership is based on the practical allocation of data to its owner. The owner, usually an organizational entity, a person, or a group of people, checks the data and is responsible for its scope and content. Data ownership shows in which Desigo system product the data is located and which tools are available for its management. Data ownership is divided in four groups.
The following table shows the four data ownership groups.
Software of a Desigo system product with basic data blocks.
Research & Development (R&D) (HQ)
Collection of predefined, specific, and tested program elements.
Library manager (HQ/RC)
All data for the customer project or customer plant.
Data from the customer plant saved permanently following commissioning.
