PLC_Stop

PLC_Stop 1:

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

VAR_INPUT

VAR_INPUT
    NETID  : T_AmsNetId;
    PORT   : T_AmsPort;
    STOP   : BOOL;
    TMOUT  : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

NETID: This parameter can be used to specify the AmsNetID of the TwinCAT computer on which the PLC is to be stopped (type: T_AmsNetID). If the PLC to be stopped is 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 stopped (type: T_AmsPort).

STOP: 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.

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 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.
