MC_DigitalCamSwitch - General Information

Overview

Type:	Function Block
Available as of:	1.0.5.0
Versions:	current version

Task

A cam switch for outputs is to be attached to the axis.

Description

One or several tracks are allocated to the axis, which are managed in the MC_Track_Ref structure. Each track switches a digital output Switches that are managed in the MC_Cam_Switch_Ref structure are placed on the tracks. Depending on the position of the axis, the switches set or reset the digital output of the track to which they are allocated.

Interface

Input	Data type	Description
Axis	SystemConfigurationItf.IF_Drive	The axis to which the cam switch is to be attached.
Switches	MC_Cam_Switch_Ref	The structure in which the switches are managed.
TrackOptions	MC_Track_Ref	The structure in which the tracks are managed.
Enable	BOOL	Releases the Switches outputs
EnableMask	WORD	16 bits of BOOL Releases various tracks The less relevant the data, the lower the track number. The respective track number is released using the data SET (to 1 or TRUE).

Output	Data type	Description
InOperation	BOOL	The outputs of the enabled tracks are set.
Busy	BOOL	The function block is not finished and new output values are still pending.
Error	BOOL	Signalizes a detected error within the function block
ErrorId	DWORD	Error identification
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	Busy	1	The order is executed.
OK	InOperation	7	The order is executed.
OK	Ok	0	Ok
InputParameterInvalid	AxisInvalid	25	The connected drive is not supported.

AxisInvalid

Enumeration name:	AxisInvalid
Enumeration value:	25
Description:	The connected drive is not supported.

Issue	Cause	Solution
-	No drive has been applied at the input Axis.	A valid drive must be transferred to the input Axis.

Busy

Enumeration name:	Busy
Enumeration value:	1
Description:	The order is executed.

The cam switch is attached.

DriveInvalid

Enumeration name:	DriveInvalid
Enumeration value:	26
Description:	The connected drive is invalid.

Issue	Cause	Solution
-	The drive connected at the input Axis does not support all required functionalities.	The drive must support the SystemConfigurationItf.IF_RefActualValuesPosition interface. The drive must support the SystemConfigurationItf.IF_RefActualValuesVelocity interface.

Issue

Cause

Solution

The drive connected at the input Axis does not support all required functionalities.

The drive must support the SystemConfigurationItf.IF_RefActualValuesPosition interface.

The drive must support the SystemConfigurationItf.IF_RefActualValuesVelocity interface.

DriveNotInitialised

Enumeration name:	DriveNotInitialised
Enumeration value:	27
Description:	The connected drive is not initialized.

Issue	Cause	Solution
-	The function FC_DriveInit was not activated for the drive at the input Axis.	Before using the POU, the drive must be initialized using the function FC_DriveInit.

InOperation

Enumeration name:	InOperation
Enumeration value:	7
Description:	The order is executed.

The cam switch is enabled.

Enumeration name:	Ok
Enumeration value:	0
Description:	Ok
