Command 'Use Attributed Member as Input'

Symbol: _cds_icon_cfc_processvalue

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

Call: Menu bar: “CFC Pins”; context menu: “Pins”

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 must be provided with the pragma ‎{attribute 'ProcessValue'}‎. 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.

Example

TYPE QINT :
STRUCT
	Status : STRING;
	{attribute 'ProcessValue'}
	Value1 : INT;
	Value2 : INT;
END_STRUCT
END_TYPE

PROGRAM PLC_PRG
VAR
	input1: QINT;
	output1: QINT;
	intValue: INT;
END_VAR
