    sNetId      : T_AmsNetId;
    hFile       : UINT;
    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.

hFile    : Is occupied by the file handle already created by FB_FileOpen.

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;
    bEOF        : BOOL;
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.

bEOF:   This output is switched to TRUE if the end of file is reached.

Example of calling the block in FBD:

PROGRAM Test
VAR
    fbEOF       : FB_EOF;
    hFile       : UINT;
    bFileEOF    : BOOL;
    bEOFBusy    : BOOL;
    bEOFError   : BOOL;
    nEOFErrorId : UDINT;
    bIsEOF      : BOOL;
END_VAR
