## Abstract

A controller for a machine tool or production machine is disclosed. The controller includes system software that implements a control function for the machine tool or production machine, real-time basic application software and real-time custom-designed application software for expanding the system software, and a software interface allowing the real-time basic application to access data and functions of the system software. The controller further includes a custom-designed software interface provided by the basic application software for communication between the basic application software and the custom-designed application software. With the disclosed controller, custom-designed application software can be integrated in the system software of the controller without detailed information about the system software of the controller.

## Claims

### Claim 1

A controller for a machine tool or production machine, comprising:
system software that implements a control function for the machine tool or production machine,
real-time basic application software and a real-time custom-designed application software for expanding the system software, and
software interface allowing the real-time basic application to access data and functions of the system software, and
a custom-designed software interface provided by the basic application software for communication between the basic application software and the custom-designed application software.

### Claim 2 (depends on 1)

The controller of claim 1, wherein the basic application software includes a monitoring functionality for monitoring the custom-designed application software.

### Claim 3 (depends on 2)

The controller of claim 2, wherein the monitoring functionality monitors a runtime of the custom-designed application software.

### Claim 4 (depends on 2)

The controller of claim 2, wherein the monitoring functionality monitors a size of machine code of the custom-designed application software.

### Claim 5

A controller for controlling a machine tool or production machine, comprising:
system software that controls a task of the machine tool or production machine;
basic application software executing in real time and interfacing with the system software for accessing data or functions, or both, of the system software; and
custom-designed application software executing in real time and interfacing with the basic application software via a custom-designed software interface of the custom-designed application software,
said custom-designed application software defining the data or functions, or both, of the system software accessible to the custom-designed application software, without requiring the custom-designed application software to have information about the system software.

### Claim 6 (depends on 5)

The controller of claim 5, wherein the basic application software includes a monitoring functionality for monitoring the custom-designed application software.

### Claim 7 (depends on 6)

The controller of claim 6, wherein the monitoring functionality monitors a runtime of the custom-designed application software.

### Claim 8 (depends on 6)

The controller of claim 6, wherein the monitoring functionality monitors a size of machine code of the custom-designed application software.
