Command: Use Attributed Member as Input

Symbol:

Function: The command allows for connecting a structure member to a scalar type input.

Call: CFC → Pins menu, Pins in the context menu

Requirements: A CFC editor is active and a function block input is selected.

The member of the structure that is connected to the input of the subsequent function block has to be provided with the {attribute 'ProcessValue'} pragma. The data type of the structure member has to be compatible with the data type of the subsequent input. Inputs connected in this way are flagged with the V symbol.

        {attribute 'ProcessValue'}
        Value1 : INT;

END_STRUCT

        input1: QINT;
        output1: QINT;
        intValue: INT;
