FC_NormalizeVector3D

FC_NormalizeVector3D - General Information

Overview

Task

Normalizes a 3-dimensional vector with regard to the Euclidean Norm.

Description

This normalies the vector i_stV with regard to the Euclidean default, that is the vector is calculated:

Interface

Input	Data type	Description
i_stV	ST_Vector3D	Vector to be normalized

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

Data type

Description

q_etDiag

General library-independent statement on the diagnostic.

A value not equal to ET_Diag.Ok corresponds to an diagnostic message.

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
ST_Vector3D	Unit vector with the same direction as i_stV

Diagnostic Messages

q_etDiag	q_etDiagExt	Enumeration value	Description
OK	Ok	0	Ok

The unit vector has been calculated successfully.
