Abstract
A programmable industrial controller, in particular CNC controller, can be controlled by a sequence of control commands which can be interpreted and executed by the controller. A program for the controller is produced by automatically encoding the original sequence of control commands into a binary code, from which the original sequence of control commands can be reconstructed. The binary code is provided to the controller and stored in the controller. The original sequence of control commands is reconstructed in the controller, whereafter the program is executed. The controller controls a controlled device, such as a machine tool, immediately after the original control commands have been reconstructed.
Claims24
A method for programming a programmable industrial controller, comprising the steps of:
- automatically coding into a binary code an original sequence of control commands capable of being interpreted and executed by the controller;
- supplying the binary code to the controller;
- and
- reconstructing the original sequence of the control commands in the controller;
- wherein the binary code representing the sequence of control commands is encrypted and includes an individualization code which limits execution of the sequence of control commands to a specific controller.
A method for programming a programmable industrial controller, comprising the steps of:
- automatically coding into a binary code an original sequence of control commands capable of being interpreted and executed by the controller;
- supplying the binary code to the controller;
- reconstructing the original sequence of the control commands in the controller,
- controlling a controlled device with the reconstructed original sequence of the control commands;
- and
- deleting from the controller the reconstructed original sequence of the control commands after operation of the controller.
A method for operating a programmable industrial controller, comprising the steps of:
- reconstructing a sequence of control commands from a binary code stored in the controller, with the controller capable of interpreting and executing the control commands;
- controlling with the reconstructed sequence of control commands a controlled device;
- and
- deleting from the controller the reconstructed original sequence of the control commands after operation of the controller.
A computer program, residing on a computer-readable medium, comprising instructions for causing a programmable industrial controller to:
- reconstruct a sequence of control commands from a binary code stored in the controller, with the controller capable of interpreting and executing the control commands,
- control with the reconstructed control commands a controlled device, such as a machine tool and
- delete from the controller the reconstructed original sequence of the control commands after operation of the controller.
A programmable industrial controller capable of interpreting and executing control commands, the controller comprising:
- means for reconstructing a sequence of control commands from a binary code stored in the controller;
- means for controlling with the reconstructed sequence of control commands a controlled device, such as a machine tool;
- and
- means for deleting from the controller the reconstructed original sequence of the control commands after operation of the controller.
