FB_FilePuts
![FB_FilePuts 1:](Images/png/9007199285962763__Web.png)
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.
Inputs
VAR_INPUT
sNetId : T_AmsNetId;
hFile : UINT;
sLine : T_MaxString;(* string to write *)
bExecute : BOOL;
tTimeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR
Name | Type | 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). |
bExecute | BOOL | The function block is activated by a rising edge at this input. |
tTimeout | TIME | States the length of the timeout that may not be exceeded by execution of the ADS command. |
Outputs
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:
