● 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 are the local subroutines responsible for the internal
consistency of setup, startup, shutdown, navigation and display, etc. among the
individual components.
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 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.
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.
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.
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 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
