PLC_Start 1:

The function block "PLC_Start" can be used to start a PLC run-time system on a TwinCAT computer. The function block can, for instance, be used to start the PLC on a remote PC.


    NETID  : T_AmsNetId;
    PORT   : T_AmsPort;
    START  : BOOL;

NETID: This parameter can be used to specify the AmsNetID of the TwinCAT computer on which the PLC is to be started (type: T_AmsNetID). If the PLC is to be started on the local computer, an empty string can be entered.

PORT: Contains the ADS port number of the PLC run-time system that is to be started (type: T_AmsPort).

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.
