FC_ScalarProduct3D - General Information

Overview

Task

Calculates the scalar product of two 3-dimensional vectors.

Description

This calculates the scalar product of the vectors i_stV1 and i_stV2.

Interface

Input	Data type	Description
i_stV1	ST_Vector3D	Vector 1
i_stV2	ST_Vector3D	Vector 2

Output	Data type	Description
q_etDiag	GD.ET_Diag	General library-independent statement on the diagnostic. A value not equal to ET_Diag.Ok corresponds to an diagnostic message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnostic. q_etDiag = ET_Diag.Ok -> Status message q_etDiag <> ET_Diag.Ok -> Diagnostic message

Output

q_etDiagExt

POU-specific output on the diagnostic.

q_etDiag = ET_Diag.Ok -> Status message

q_etDiag <> ET_Diag.Ok -> Diagnostic message

Return Value

Data type	Description
LREAL	Scalar product i_stV1 * i_stV2
