PLC_Reset 1:

The "PLC_Reset" function block can be used to reset a PLC run-time system. When the PLC is reset, the PLC variables are filled with their initial values, and the execution of the PLC program is stopped.


    NETID  : T_AmsNetId;
    PORT   : T_AmsPort;
    RESET  : BOOL;

NETID: It is possible here to provide the AmsNetId of the TwinCAT computer on which the PLC run-time system is to be reset (type: T_AmsNetID). If the PLC reset is to be carried out 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 reset (type: T_AmsPort).

RESET: 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.
