Task

Generation of a segmented cam

Description

Based on the array i_astCamSegments, this method generates a segmented cam with i_diNumberOfSegments segments. Ensure that the values ST_Cam.lrXEnd and ST_Cam.lrYEnd of a segment correspond to the values ST_Cam.lrXStart and ST_Cam.lrYStart of the following segment.

Interface

Input	Data type	Description
i_diNumberOfSegments	DINT	Number of segments
i_astCamSegment	ARRAY[1..Gc_diMaxNumberOfCamSegments] OF	Structure for parameterization of the individual segments.

Output	Data type	Description
q_etDiag	GD.ET_Diag	General library-independent statement on the diagnostic. A value unequal to GD.ET_Diag.Ok corresponds to a diagnostic message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnostic. q_etDiag = GD.ET_Diag.Ok -> status message q_etDiag <> GD.ET_Diag.Ok -> diagnostic message
q_sMsg	STRING[80]	Event-triggered message which gives more detailed information on the diagnostic state.

Output

Data type

Description

q_etDiag

GD.ET_Diag

General library-independent statement on the diagnostic.

A value unequal to GD.ET_Diag.Ok corresponds to a diagnostic message.

q_etDiagExt

ET_DiagExt

POU-specific output on the diagnostic.

q_etDiag = GD.ET_Diag.Ok -> status message

q_etDiag <> GD.ET_Diag.Ok -> diagnostic message

q_sMsg

STRING[80]

Event-triggered message which gives more detailed information on the diagnostic state.

Diagnostic Messages

q_etDiag	q_etDiagExt	Enumeration value	Description
OK	Ok	0	Ok
InputParameterInvalid	JobTypeUnknown	67	JobType is indeterminable.
InputParameterInvalid	NumberOfSegmentsRange	66	NumberOfSegments is routside the valid range.
InputParameterInvalid	XendMustBeEqualXstart	68	Xend and Xstart must be equal.
InputParameterInvalid	XstartGreaterXend	65	XStart is greater than XEnd.
InputParameterInvalid	YendMustBeEqualYstart	69	Yend and Ystart must be equal.

JobTypeUnknown

Enumeration name:	JobTypeUnknown
Enumeration value:	67
Description:	JobType is indeterminable.

Issue	Cause	Solution
-	A segment of the segmented cam contains no valid cam entry.	The q_sMsg output shows which cam is faulty.

NumberOfSegmentsRange

Enumeration name:	NumberOfSegmentsRange
Enumeration value:	66
Description:	NumberOfSegments is routside the valid range.

Issue	Cause	Solution
-	The number of segments of the segmented cam is invalid.	The number of segments must be <= Gc_diMaxNumberOfCamSegments.

Enumeration name:	Ok
Enumeration value:	0
Description:	Ok

The generation of a segmented cam was successful.

XendMustBeEqualXstart

Enumeration name:	XendMustBeEqualXstart
Enumeration value:	68
Description:	Xend and Xstart must be equal.

Issue	Cause	Solution
-	In the case of two consecutive segments of a segmented cam lrXend <> lrXStart.	Set lrXend of the previous segment equal to lrXStart of the subsequent segment. The q_sMsg output shows which segments are incorrect.

Issue

Cause

Solution

In the case of two consecutive segments of a segmented cam lrXend <> lrXStart.

Set lrXend of the previous segment equal to lrXStart of the subsequent segment.

The q_sMsg output shows which segments are incorrect.

XstartGreaterXend

Enumeration name:	XstartGreaterXend
Enumeration value:	65
Description:	XStart is greater than XEnd.

Issue	Cause	Solution
-	The assigned value of the lrXStart variable of a segment is too high.	The value of the lrXStart variable must be less than the value of the lrXEnd variable of a segment.

YendMustBeEqualYstart

Enumeration name:	YendMustBeEqualYstart
Enumeration value:	69
Description:	Yend and Ystart must be equal.

Issue	Cause	Solution
-	In the case of two consecutive segments of a segmented cam lrYend <> lrYStart.	Set lrYend of the previous segment equal to lrYStart of the subsequent segment. The q_sMsg output shows which segments are incorrect.

Issue

Cause

Solution

In the case of two consecutive segments of a segmented cam lrYend <> lrYStart.

Set lrYend of the previous segment equal to lrYStart of the subsequent segment.

The q_sMsg output shows which segments are incorrect.
