FC_DistanceTwoLineSegments3D

FC_DistanceTwoLineSegments3D - General Information

Overview

Task

Calculates the distance between two line segments in the 3-dimensional space.

Description

Calculates the distance between the line segments i_stLineSegment1 and i_stLineSegment2 in the 3-dimensional space.

Interface

Input	Data type	Description
i_stLineSegment1	ST_LineSegment3D	Line segment 1
i_stLineSegment2	ST_LineSegment3D	Line segment 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
q_lrDistance	LREAL	Calculated distance between i_stLineSegment1 and i_stLineSegment2

Output

q_etDiagExt

POU-specific output on the diagnostic.

q_etDiag = ET_Diag.Ok -> Status message

q_etDiag <> ET_Diag.Ok -> Diagnostic message

q_lrDistance

LREAL

Calculated distance between i_stLineSegment1 and i_stLineSegment2

Diagnostic Messages

q_etDiag	q_etDiagExt	Enumeration value	Description
