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_diNumberOfCommonPoints

DINT

Number of common points Possible values:

2: There are two intersections (the straight line is a secant). This includes the case of a tangent (in such a case the following holds: q_astCommonPoints[1] = q_astCommonPoints[2]).

0: There are no intersections (the straight line is a passant).

q_astCommonPoints

ARRAY [1..2] OF ST_Vector2D

Intersections of i_stCircle and i_stLine (if q_diNumberOfCommonPoints = 2)

q_lrParameterLine1

LREAL

Parameters of q_astCommonPoint[1] in the default parameter representation of the straight line i_stLine (see ST_Line2D).

q_lrParameterLine2

LREAL

Parameters of q_astCommonPoint[2] in the default parameter representation of the straight line i_stLine (see ST_Line2D).

RadiusRangeCircle

26

The radius of the circle is outside the valid range.

Enumeration name:

DefinitionLine

Enumeration value:

31

Description:

The definition of Line is not correct.

-

At the inputs i_stLine.stPoint1 and i_stLine.stPoint2, the same point has been transferred.

The distance between the points stPoint1 and stPoint2 which define the straight line i_stLine must be at least Gc_lrZeroTolerance.

Enumeration name:

RadiusRangeCircle

Enumeration value:

26

Description:

The radius of the circle is outside the valid range.

-

At the input i_stCircle.lrRadius, a number <= 0 has been transferred.

The radius of the circle must be greater than zero.
