Overview

Type:	Function
Available as of:	V1.0.3.0
Versions:	Current version

Task

Convert planar polar coordinates into 2 dimensional Cartesian coordinates.

Description

The polar coordinates are converted to cartesian coordinates. In doing so, it is assumed that the pole of the polar coordinate system corresponds to the origin of the cartesian coordinate system and that the horizontal axis of the polar coordinate system corresponds to the X axis of the cartesian coordinate system.

Interface

Input	Data type	Description
i_stPoint	ST_PlanarPolarCoordinates	Point defined by polar coordinates

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
