Abstract

According to the invention, the operating software 10 of a technical system, particularly of a controller for controlling or regulating at least one technical device, is modified by virtue of hardware-dependent software components in the operating software 10 executable directly on the technical system not being executed and instead the functional behavior of the hardware-dependent software components being recreated by substitute functions 23. To this end, the hardware-dependent software components are automatically identified (step S1), and the substitute functions 23 are automatically ascertained or produced. On execution in a suitable simulation environment 200 (step S3), the operating software 20 modified in this way simulates the technical system independently of the real hardware 100 thereof.

Claims13

Dependent claims

A method for modifying operating software of a technical system, particularly of a controller for controlling or regulating at least one technical device, comprising the step of providing the operating software executable directly on the technical system, characterized by the further steps of:

automatically identifying software components of the operating software whose execution is dependent on the hardware of the technical system;
and
replacing the identified, hardware-dependent software components with substitute functions whose execution is independent of the hardware of the technical system,
wherein the operating software modified in this manner simulates the technical system on execution on a simulation environment independently of the hardware of the technical system,
wherein the operating software is provided in the form of a binary code executable on the technical system, and the hardware-dependent software components in the binary code of the operating software are identified by using interface specifications, and
wherein the interface specifications specify binary code patterns that are specific to the hardware of the technical system.
