TC_Config 1:

A TwinCAT system in RUN mode (green TwinCAT system icon) can be switched to CONFIG mode (blue TwinCAT system icon) via the function block "TC_Config". If the system is already in CONFIG mode, it is first switched to STOP mode (red TwinCAT system icon) and then to CONFIG mode.


    NETID  : T_AmsNetId;
    SET    : BOOL;

NETID: This parameter can be used to specify the AmsNetId of the TwinCAT computer that is to be switched to CONFIG mode (type: T_AmsNetID). If it is to be run on the local TwinCAT computer, an empty string can be entered.

SET: 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.
