FB_FilePuts

FB_FilePuts 1:

The function block writes strings into a file. The string is written to the file up to the null termination, but without the null character. The file must have been opened in text mode.

FB_FilePuts 2: Inputs

Description

sNetId

T_AmsNetId

String containing the AMS network ID of the target device to which the ADS command is addressed (type: T_AmsNetId).

hFile

UINT

File handle, which was generated when the function block FB_FileOpen was created.

sLine

T_MaxString

String to be written into the file (type: T_MaxString).

VAR_OUTPUT
    bBusy  : BOOL;
    bError : BOOL;
    nErrId : UDINT;
END_VAR

Name

Type

Description

bBusy

BOOL

When the function block is activated, this output is set to TRUE and remains set until feedback is received. As long as bBusy is TRUE, no new command can be executed.

bError

BOOL

If an error occurs during command execution, this output is set, once the bBusy output has been reset.

nErrId

UDINT

Returns the ADS error code or the command-specific error code when the bError output is set.

Command-specific error code

Possible cause

0x703

Invalid or unknown file handle.

0x70E

File was opened with wrong method (e.g. with obsolete FILEOPEN function block).

Example of calling the function block in FBD:

PROGRAM Test
VAR
    fbFilePuts       : FB_FilePuts;
    hFile            : UINT;
    bFilePuts        : BOOL;
    bFilePutsBusy    : BOOL;
    bFilePutsError   : BOOL;
    nFilePutsErrorId : UDINT;
END_VAR
