FB_DeclampingStation - General Information

Overview

Type:	Function block
Available as of:	V1.0.0.0
Inherits from:	FB_CoreStandardStation
Implements:	–

Task

Implementing a station where pairs of carriers are declamped for releasing the transported product.

Description

A declamping station can be used to unload a product that has been transported by two carriers. After declamping, the carriers move out of the station either as single carriers or as pairs of carriers keeping the gap within the pair.

NOTE: For the correct functioning of the station, the carriers must be paired when they are handed over to the declamping station. In the moving direction, the second (connected) carrier must be behind the first carrier of the pair.

For a visual illustration of the declamping process, refer to the DeclampingStation video sequence.

Properties

Name	Data type	Accessing	Description
xEnable	BOOL	Write	If xEnable is set to TRUE, the station is enabled (activated).
xError	BOOL	Read	Indicates TRUE if an error has been detected. For details, refer to etResult and sResultMsg.
xErrorQuit	BOOL	Write	When an error is detected, state machine is going to a WAITING state. If xErrorQuit is set to TRUE, you leave this WAITING state and reset the error variables.
xStationReadyForDeclamping	BOOL	Read	Indicates TRUE if the pairs of carriers are ready for declamping and are waiting for the parameter iq_xTriggerDeclamping to become TRUE (see method CyclicMotionCall ).
xStationReadyForMoveOut	BOOL	Read	Indicates TRUE if the carriers in the station have declamped the product, are ready to move out of the station and are waiting for the parameter iq_xTriggerMoveOut to become TRUE (see method CyclicMotionCall ).
The following properties come from the hidden function block FB_CoreStandardStation:
etResult	ET_Result	Read	Provides diagnostic and status information as a numeric value. If xError = FALSE, etResult provides status information. If xError = TRUE, etResult provides diagnostic/error information.
ifAdditionalControls	IF_ControlStandardStation	Read	Access to the interface IF_ControlStandardStation that provides methods for controlling the standard station.
sResultMsg	STRING [255]	Read	The event-triggered property sResultMsg provides additional diagnostic and status information as a text message.
xActive	BOOL	Read	Indicates TRUE if the function block is enabled.
xReady	BOOL	Read	Indicates TRUE if the function block is enabled and no error is active. Indicates FALSE if the function block is enabled and an error is active or if the function block is disabled.
