3.5.6 FILE_TELL
The FILE_TELL block is used to determine the current position of the file pointer in a file.
Figure 3-7 FILE_TELL block
In order to determine the current position of the file pointer (relative offset from start of file),
the valid handle for the file is assigned to “Handle”.
• Activate the block on a rising edge at the “Execute” input.
The execution of the function block is complete when the “Done” output is set to 1.
The current position of the file pointer can be read at the “Position” output following
successful execution.
If an error occurred during execution, the value at the “Error” output = 1.
“ErrorID” indicates the number of the cause of the error.
The status of the “Done”, “Position”, “Error”, and “ErrorID” outputs is maintained until a falling
edge is detected at the “Execute” input.
