ST_Vehicle - General Information

Overview

Type:	Data structure
Available as of:	V1.0.4.0
Inherits from:	-

Description

The structure contains the data for a vehicle on the transport system.

Structure Elements

Variable	Data type	Description
i_xExecute	BOOL	A positive edge orders the function block to send the command specified in the input i_etCommand to the vehicle which is controlled by this function block. If the inputi_xExecute (FB itself, iq_aST_Path and iq_aST_Vehicle) is set = TRUE before the FB is enabled and the FB will be turned on, the FB is detecting this as a rising edge. This is the criteria to execute a command (status requests or movements). Note: the setting i_xExecute = TRUE before enabling the function block is also considered a rising edge
i_etCommand	ET_VehicleCommand	The command which is send to the vehicle on a positive flank of i_xExecute.
i_iPidSet	INT	Number relating to predefined parameter sets for the PID-Controllers when moving a vehicle.
iq_stDestination	ST_VehicleDestination	Structure that contains the information to send a vehicle to a new destination.
iq_stCurrentPosition	ST_VehiclePosition	Structure that contains the information relating to the present position of the vehicle.
q_xValid	BOOL	TRUE: The vehicle is present on the transport system. FALSE: The vehicle is not present on the linear transport system.
q_uiVehicleId	UINT	The ID of the vehicle as it was defined by the transport system on startup/ reset.
q_xBusy	BOOL	TRUE: The POU is executing the command. FALSE: The POU is waiting for further commands.
q_xDone	BOOL	TRUE: The command has been executed. FALSE: The command is being executed, or none has been issued yet.
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.
