VAR_INPUT

VAR_INPUT
    NETID       :T_AmsNetId;
    PATHSTR     :T_MaxString;
    DIRNAME     :T_MaxString;
    COMNDLINE   :T_MaxString;
    START       :BOOL;
    TMOUT       :TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

NETID: It is possible here to provide the AmsNetId of the TwinCAT computer on which the application is to be started. If it is to be run on the local computer, an empty string can be entered.

PATHSTR: The full path to the application that is to be run, in the form of a string (e.g. "C:\WINNT\NOTEPAD.EXE" ).

DIRNAME: Working directory of the application that is to be executed, as a string (e.g. "C:\WINNT" ).

COMNDLINE: Command line parameters (e.g.: "win.ini").

START: The function block is activated by a positive edge at this input.

TMOUT: States the length of the timeout that may not be exceeded by execution of the ADS command.

VAR_OUTPUT

VAR_OUTPUT
    BUSY         :BOOL;
    ERR          :BOOL;
    ERRID        :UDINT;
END_VAR

BUSY: When the function block is activated this output is set. It remains set until and acknowledgement is received.

ERR: If an ADS error should occur during the transfer of the command, then this output is set once the BUSY output is reset.

ERRID: Supplies the ADS error number or Win32 error number (Platform SDK: Win32 API) when the ERR output is set.
