VAR_INPUT

VAR_INPUT
    sNetId      : T_AmsNetId;          
    sPathName   : T_MaxString;            (* file path and name *)
    ePath       : E_OpenPath := PATH_GENERIC;  
    bExecute    : BOOL;             
    tTimeout    : TIME;
END_VAR

sNetId    : Is a string containing the AMS network identifier of the target device to which the ADS command is directed.

sPathName    : Contains the path and filename for the file to be deleted. 

ePath    : The variable of this type selects generic or one of the TwinCAT system paths on the target device to perform the file open operation.

bExecute    : The ADS command is triggered by a rising edge at this input.

tTimeout    : States the time before the function is cancelled.

VAR_OUTPUT

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

bBusy:    This output remains TRUE until the block has executed a command, but at the longest for the duration supplied to the ‘tTimeout’ input. While bBusy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.

bError:    This output is switched to TRUE if an error occurs during the execution of a command. The command-specific error code is contained in ‘nErrId’.

nErrId:    Contains the command-specific ADS error code of the most recently executed command.

Example of calling the block in FBD:

PROGRAM Test
VAR
    fbFileDelete    : FB_FileDelete;
    bFileDelete     : BOOL;
    bFileDeleteBusy : BOOL;
    bFileDeleteError: BOOL;
    nFileDeleteErrId: UDINT;
END_VAR
