FA_WRITE

Writes integer variables to a binary file. This procedure makes a sequential access to the file, from the previous position. The first call after F_WOPEN writes the first four bytes of the file, each call pushes the writing pointer.
IMPORTANT: Avoid using this function. This function is intended to be obsolete.
lrsf_faw1
Arguments
ID
DINT
File number: returned by F_WOPEN
IN
DINT
Integer value to be written in the file
OK
BOOL
Execution status: TRUE if ok
Example
(* FBD program using file management blocks *)
lrsf_faw2
(* ST Equivalence: *)
file_id := F_WOPEN('voltramp.bin');

nb_written := 0;

nb_written := nb_written + dint(FA_WRITE(file_id,vstart));

nb_written := nb_written + dint(FA_WRITE(file_id,vend));

nb_written := nb_written + dint(FA_WRITE(file_id,vinc));

nb_written := nb_written + dint(FA_WRITE(file_id,dint(delta_tim)));

ok := F_CLOSE(file_id);

IF ( nb_written <> 4) THEN

ERROR := ERR_FILE;

END_IF;
