Engineering Manual
In some cases when the function block input is directly mapped to the
function block output, the input is internally forced to the correct value
depending of the function block's settings. This kind of function block
design is present in control blocks, setting group handling and tap
changer.
Validation
Validation checks the application configuration for errors based on the rules that
govern the creation of the application at three different times.
•
During the logic creation, while making a connection or placing a function block
•
On demand by starting the validation
•
When writing the application configuration to the protection relay
Validation when creating an application configuration
Validation is made when creating the application configuration.
•
A connection between two input or two output signals is not possible
•
A connection between two different data types is not possible: for example, from
a binary output to an analog input
Validation on demand
The validity of an application configuration can be checked by clicking Validate
Configuration in the toolbar. The Application Configuration tool checks the
application configuration for formal correctness. The found problems are divided into
warnings and errors.
•
Warnings, marked with a yellow warning icon
•
Example: a variable connected to an output signal that is not connected
•
Example: if an output from a higher execution order function is connected
to inputs of lower execution order function
•
Errors, marked with a red circle with a cross
•
Example: unconnected hardware output
Warnings do not prevent writing to the protection relay. However, errors must be
corrected before writing the application configuration to the protection relay. The
application configuration can be saved and the Application Configuration tool can be
closed with open errors, but the application configuration cannot be written to the
protection relay.
