Description
This block tells whether or not the end of a file has been reached.
Valid hardware resources vary, but typically include a connected USB storage device, and the modules built-in non-volatile data flash memory.
As with many of the other datalogging and file I/O Raptor blocks, this block takes a file handle as an input, and propagates the same file handle through the block logic to an output of the block. By connecting the File Handle output of file I/O block 'X' to the File Handle input of file I/O block 'Y', application designers can ensure that the logic executed by block Y will be performed after the logic executed by block X.
