To describe a process object within an IED, it needs to be established in the application configuration, configured when given the parameters by the Parameter Setting tool and linked to be displayed in the HMI.
Three tools are involved in the described steps.
Application Configuration tool for programming the application function block for the apparatus and measurements
Parameter Setting tool for adapting the settings and configuration parameters of the application function block
Graphical Display Editor for establishing the link to update the selected data attribute in the HMI of the application function block
The needed information is delivered with switch controller (of type CSWI) for an apparatus and all the configured function blocks with measurements (of type MMXU) for the measurements
Right-click the apparatus symbol and select Select Input Signal.
A list of engineered switch control application function blocks opens.
Select the switch control application function block that corresponds to the selected apparatus.
Right-click the measurement symbol and select Select Input Signal.
A list of the engineered measurement application function blocks opens.
Select the measurement application function block that corresponds to the selected symbol.

The ordering number in the selection window of the process objects corresponds to the number given in the Parameter Setting tool tree and to the application function block in the Application Configuration tool.
Only the apparatus and measurements that are configured in the application configuration program are displayed.
