2.2.8 Resources
Resources are required to configure and organize your project and to trace variable values:
•
Global variables to be used throughout the entire project.
•
PLC configuration to configure your hardware.
•
Task configuration to control your program through tasks.
•
Task monitoring to monitor the task runtimes.
•
Watch and Receipt Manager to display and pre-assign variable values
•
Automation system settings for selection and, if appropriate, for final configuration of the
automation system
2.2.9 Libraries
The Library Manager can link your project to several libraries whose organization units, data types
and global variables can be used in addition to the user-defined ones.
The register card Global Variables contains the variable g_ErrorCheckBounds.
Depending on the selected PLC, some libraries are automatically linked when a new project is
created (the library ” standard.lib” , for example).
2.2.10 Data types
In addition to the standard data types, users can define some data types of their own. Structures,
enumeration types and references can be created.
2.2.11 Visualization
The DDS provides visualization to monitor and modify project variables.
The visualization allows offline drawing of geometrical elements that can then change their
shape/colour/text output online, depending on certain variable values.
