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.
