Application Configuration
Application Configuration is used to modify an application configuration for a
protection relay and is based on IEC 61131-3 Function Block Diagrams.
The function blocks are dedicated to different functions.
•
Control-related functions
•
Protection-related functions
•
Monitoring functions
•
Communication
For more information on the function blocks, see the technical manual.
Most function blocks are mapped as logical nodes according to the IEC 61850
standard. See the IEC 61850 parameter list for more information.
If a function block is removed with Application Configuration, the
function-related data disappears from the menus as well as from the
IEC 61850 data model, with the exception of some basic function
blocks, which are mandatory and thus cannot be removed from the
relay configuration by removing them from Application
Configuration.
Other function blocks are not mapped as logical nodes; for example, logical gates.
The basic features of Application Configuration include the ability to organize a
configuration into several MainApplications as well as providing different
application programming features.
•
Organizing an application configuration
•
Organizing an application configuration into a number of logical parts
(MainApplication)
•
Organizing a MainApplication over a number of pages
•
Features for programming an application configuration
•
Inserting function blocks, making connections and creating variables
•
Including the hardware I/O channels directly in the application
configuration
•
Calculating the execution order automatically by clicking Calculate
execution order on the toolbar
