System blocks for controlling the plant
System interfaces which are implemented in every component and which control the data traffic
between the components
Product components
Product components are the local subroutines responsible for the internal consistency of setup, startup,
shutdown, navigation and display, etc. among the individual components.
Parameterization
There are two parameter types:
Setting parameters: System and product components have predefined default settings. These values
are application-independent, but always lie within the system limits.
Configuration parameters: The system and product components have a basic configuration. The basic
configuration of certain blocks is not complete and must be supplemented during engineering with, e.g.,
addresses of the I/O blocks.
The library or project engineers can adapt the setting and configuration parameters to the plant or project
conditions.
13.3 Libraries
Libraries are needed during engineering. You can create loadable applications using libraries. Library
elements are compiled from system basic components, e.g., the Desigo CC graphic library contains default
graphics for visualizing plants during engineering.
You can copy and customize or extend libraries. Every engineering level has a library. Libraries can cover
many combinations.
DXR2 automation stations are delivered with preloaded applications and only need to be configured.
There are three library types:
HQ libraries are tested, well documented and delivered with the system version. Every new Desigo
version contains new libraries.
RC libraries are tested, well documented and contain country-specific characteristics. They are
optional, independent or an addendum to the HQ library. Not all RCs offer comprehensive libraries.
Project-specific libraries are not tested and documented.
Application libraries
Application libraries contain plant-specific functions (heating, cooling, control of electrical equipment, etc.)
or templates for subsystem bindings. You can set up and manage libraries with the Xworks Plus (XWP) and
Automation Building Tool (ABT) engineering tools.
PX libraries
The functional units of the PX application libraries are defined by compounds. You can copy, change and
extend the compounds of the PX library.
Application libraries for PX are designed using the same application principles and are provided via Xworks
Plus during project engineering.
PXC3/DXR2 libraries
The functional units of the PXC3/DXR2 application libraries are defined by application functions. You can
copy, change and extend the application functions of the PXC3/DXR2 library.
Parameterization
The library elements have plant-specific or function-specific setting and configuration parameters:
Setting parameters: The default values are defined by the application and usually do not require
adjustment.
Configuration parameters: The default values can be adapted as needed.
Graphics libraries
Graphics libraries contain graphics that represent the operating elements of the firmware and application
libraries. The graphics are used in Desigo CC to visualize and operate plants. The elements of the graphics
libraries depend on the elements of the application libraries. Any changes to the application libraries must
therefore also be made to the graphics libraries.
The graphics libraries for Desigo PX and PXC3/DXR2 are identical.
