NT_AbortShutdown 1:

The "NT_AbortShutdown" function block can be used to abort a shutdown command that has previously been called with the NT_Shutdown function block.

When calling the NT_Shutdown function block, a delay period can be given as a parameter. The remaining time is indicated in a message window.

NT_AbortShutdown 2:

Only after the delay time has elapsed is the operating system shut down. During this time, the shutdown process can be interrupted from the PLC with the aid of the "NT_AbortShutdown" function block.


    NETID  : T_AmsNetId;
    START  : BOOL;

NETID: It is possible here to provide the AmsNetId of the TwinCAT computer on which the shutdown process is to be aborted (type: T_AmsNetID). If it is to be run on the local computer, an empty string can be entered.

START: the 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.


    BUSY   : BOOL;
    ERR    : BOOL;

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

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

ERRID: Supplies the ADS error number when the ERR output is set.
