ST_Path

ST_Path - General Information

Overview

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

Description

The structure contains the data for a path within 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 path which is managed with this structure. If the input i_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_PathCommand	The command which is send to the path on a positive flank of i_xExecute.
q_uiPathId	UINT	The ID of the path as it was defined during configuration.
q_uiVehicles	UINT	The number of vehicles, which are on this path.
q_xValid	BOOL	TRUE: The path is present on the linear transport system. FALSE: The path is not part of the linear transport system.
q_etMovementStatus	ET_MovementStatus	Describes if/ if not and why vehicles are able to move on this path.
q_xBusy	BOOL	TRUE: The POU is executing the issued 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.

Diagnostic Messages

q_etDiag	q_etDiagExt	Enumeration value	Description
OK	Initializing	2	The transport system controller reports that the component is initializing.
OK	LocatingVehicles	37	The system is locating the vehicles.
OK	ProgrammingInProgress	39	The transport system controller reports that the path is in state "Programming In Progress".
OK	ResetActive	40	Usage in ST_Path: The transport system controller reports that the path is in state "Reset Active". Usage in ST_Vehicle: The transport system controller reports that the vehicle is in state "Reset Active".
OK	ResetInProgress	38	The transport system controller reports that the path is in state "Reset In Progress".
OK	WaitForCommand	36	Wait for a new command.
UnexpectedProgramBehavior	PathStateUnknown	41	The response from the transport system controller cannot be interpreted: A path is in an undefined state.
