FB_TrackCalibration - General Information

Overview

Type:	Function block
Available as of:	V1.2.5.0

Task

Calibrating the segment transitions of a Lexium™ MC multi carrier track.

Description

Since the segments might not be spaced equally, a track calibration can improve the motion quality of the carrier when transitioning from segment to segment.

The function block FB_TrackCalibration provides the following property and methods for performing a track calibration:

the method StartCalibration
the method StartMeasurement
the method ResetTrackCalibration
the property etState (see ET_StateTrackCalibration)

The instance of the function block FB_TrackCalibration must be called cyclically.

Properties

Name	Data type	Accessing	Description
etState	ET_StateTrackCalibration	Read	Access to the enumeration ET_StateTrackCalibration that displays the status of the running track calibration sequence.

Inputs

Input	Data type	Description
i_xEnable	BOOL	A rising edge FALSE -> TRUE activates and initializes the function block, a falling edge TRUE -> FALSE deactivates the function block. A deactivated function block does not execute actions and the outputs are set to the default value.
i_xStart	BOOL	A rising edge of the input starts the function block.
i_ifMulticarrier	IF_Multicarrier	Interface for assigning the function block FB_Multicarrier.

Outputs

Output	Data type	Description
q_xActive	BOOL	Indicates TRUE if the execution of the function block is active. As long as the output is TRUE, the function block must be executed cyclically.
q_xReady	BOOL	Indicates TRUE if the function block is ready and can be controlled through its inputs according to its functionality. After the function block has been enabled with a rising edge of i_xEnable, the output q_xReady is only set to TRUE if the function block can process instructions from the inputs. If invalid input values are detected during initialization, q_xReady remains FALSE. If the function block has detected an error, q_xReady is set to FALSE. If the function block is deactivated using i_xEnable, q_xReady immediately becomes FALSE.
q_xError	BOOL	Indicates TRUE if an error has been detected. For details, refer to q_etResult and q_sResultMsg.
q_etResult	ET_Result	Provides diagnostic and status information as a numeric value. If q_xError = FALSE, q_etResult provides status information. If q_xError = TRUE, q_etResult provides diagnostic/error information.
q_sResultMsg	STRING [255]	Provides additional diagnostic and status information as a text message.
