3.5.7 FILE_SEEK
The FILE_SEEK block is used to move the current file pointer to a new position.
Figure 3-8 FILE_SEEK block
• Assign the valid handle of the file to be processed to the “Handle” input.
• Write the relative offset to be used to move the file pointer to the “Position” input.
• Enter the reference to be used to move the pointer at the “Mode” input (see Table 3-8
on page 57).
• 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.
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”, “Error”, and “ErrorID” outputs is maintained until a falling edge is
detected at the “Execute” input.
