FBFileTransfer (FB)¶

FUNCTION_BLOCK PUBLIC FBFileTransfer EXTENDS FbExecuteSingleVisuActionBase

Requests a file transfer between visualization and PLC

To use this function block in the program, assign the input values and start the action with xExecute = TRUE.

The fb-instance should be declarated within a permanent setting, e.g. a GVL, and not within a temporary setting, e.g. a function. Therefore, the action will still be available, when called, later on.

InOut:

Scope	Name	Type	Comment	Inherited from
Input	xExecute	BOOL	Rising edge: Starts defined operation FALSE: Resets the defined operation after ready condition was reached	ETrig
Output	xDone	BOOL	TRUE: Ready condition reached	ETrig
	xBusy	BOOL	TRUE: Operation is running	ETrig
	xError	BOOL	TRUE: Error condition reached	ETrig
Input	itfClientFilter	IVisualizationClientFilter	With this filter, the clients, where the action should happen, are specified. Use standard filter from GVL Globals, e.g. VU.Globals.CurrentClient, or use a own implentation of the interface.	FbExecuteSingleVisuActionBase
Output	eError	ERROR		FbExecuteSingleVisuActionBase
Input	eDirection	VisuElemBase.VisuEnumFileTransferDirection	Direction of the file transfer, either from the visualization to the PLC or from the PLC to the visualization.
	sPlcFilePath	STRING(255)	The path to the file on the PLC.
	sOptVisuFilePath	STRING(255)	Optional path to the file in the visualization. If an empty string is passed, a file dialog will open to ask for the path.
