IF_TargetManager - AddTargetPos (Method)

Overview

Task

Create a target at a position on the target belt.

Description

Adds a new target to the list of targets that is located at the i_lrPosition position of the target belt.

Interface

Input	Data type	Description
i_lrPosition	LREAL	Position of the target belt at which the target is to be entered

Output	Data type	Description
q_etDiag	GD.ET_Diag	General, library-independent statement on the diagnosis. A value unequal GD.ET_Diag.Ok equates an error message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnosis. q_etDiag = GD.ET_Diag.Ok -> status message q_etDiag <> GD.ET_Diag.Ok -> error message

Output

Data type

Description

q_etDiag

General, library-independent statement on the diagnosis.

A value unequal GD.ET_Diag.Ok equates an error message.

q_etDiagExt

POU-specific output on the diagnosis.

q_etDiag = GD.ET_Diag.Ok -> status message

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

Diagnostic Messages

q_etDiag	q_etDiagExt	Enumeration value	Description
OK	Ok	0	Ok
ExecutionAborted	MaxNrOfTargetsReached	74	The maximum number of manageable targets has been reached.
InputParameterInvalid	PositionInvalid	75	The position is invalid.

MaxNrOfTargetsReached

Enumeration name:	MaxNrOfTargetsReached
Enumeration value:	74
Description:	The maximum number of manageable targets has been reached.

Issue	Cause	Solution
-	There was an attempt to add more than the maximum number of targets to the infeed distance.	At no time more than Gc_udiMaxNumberOfTargets targets may be defined for the infeed distance. The global parameter Gc_udiMaxNumberOfTargets must be set to a value that is greater than the maximum number of targets for the infeed distance.

Issue

Cause

Solution

There was an attempt to add more than the maximum number of targets to the infeed distance.

At no time more than Gc_udiMaxNumberOfTargets targets may be defined for the infeed distance.

The global parameter Gc_udiMaxNumberOfTargets must be set to a value that is greater than the maximum number of targets for the infeed distance.

The target has been added successfully.

PositionInvalid

Issue	Cause	Solution
-	An invalid value has been transferred at the input i_lrPosition.	It must be made sure that a position that is located further away from the target belt than the last target is transferred at the input i_lrPosition. This ensures a consistent target sequence.
