Numeric controller with notification of a cam system in the event of a change in the subroutine

A method for operating a numeric controller, comprising:

• loading a subroutine executable by the numeric controller to control a production machine into memory accessible to the numeric controller;
• entering a command into the numerical controller that selects at least one program statement of the subroutine using an operator interface;
• outputting a parameterized description of a selected program statement or a sequence of program statements containing a selected program statement to the operator of the numeric controller using an operator interface;
• inputting a change in the parameterized description to the numerical control unit using an operator interface;
• storing a modified subroutine corresponding to the changed parameterized description in the numeric controller;
• compulsorily sending a message that identifies the original subroutine and the change made therein to a predetermined address so that the CAM system that was used to create the subroutine can autonomously and automatically use the message to ascertain a data set underlying the original subroutine and to modify the data set in accordance with the change that was made therein as well as storing the modified subroutine, the message that identifies the original subroutine and the change made therein being in a form that is automatically evaluable.

A computer program, wherein the computer program is machine code configured for execution by a numerical control unit to control a production machine, the computer program comprising:

• machine code configured to load a subroutine executable by the numeric controller into memory accessible to the numeric controller;
• machine code configured to enter a command into the numerical controller that selects at least one program statement of the subroutine using an operator interface;
• machine code configured to output a parameterized description of a selected program statement or a sequence of program statements containing a selected program statement to the operator of the numeric controller using the operator interface;
• machine code configured to input a change in the parameterized description to the numerical control unit using a operator interface;
• machine code configured to store a modified subroutine corresponding to the changed parameterized description in the numeric controller;
• and
• machine code configured to compulsorily send a message that identifies the original subroutine and the change made in a form that is automatically evaluable to a predetermined address, so that the CAM system that was used to create the subroutine autonomously and automatically uses the message to ascertain a data set underlying the original subroutine and to modify the data set in accordance with the change that was made as well as storing the modified subroutine.

A numeric controller, comprising:

• an operator interface;
• and
• a computer program stored in the numerical control unit, the computer program including a sub-program executable by the numerical control unit to control a production machine, the sub-program including:
• machine code configured to load a subroutine executable by the numeric controller into memory accessible to the numeric controller;
• machine code configured to enter a command into the numerical controller that selects at least one program statement of the subroutine using an operator interface;
• machine code configured to output a parameterized description of a selected program statement or a sequence of program statements containing a selected program statement to the operator of the numeric controller using the operator interface;
• machine code configured to input a change in the parameterized description to the numerical control unit using a operator interface;
• machine code configured to store a modified subroutine corresponding to the changed parameterized description in the numeric controller;
• machine code configured to compulsorily send a message that identifies the original subroutine and the change made in a form that is automatically evaluable to a predetermined address, so that the CAM system that was used to create the subroutine autonomously and automatically uses the message to ascertain a data set underlying the original subroutine and to modify the data set in accordance with the change that was made as well as storing the modified subroutine.
