Embodiment Construction

[0038] according to figure 1 , the schematically shown machine tool 1 is controlled by a real numerical controller 2 (CNC 2 ). For this purpose, a user program (control program) 4 , also referred to as a subroutine in connection with the CNC controller, is supplied to the numerical controller 2 , for example by the user 3 or by a control computer (not shown). In this case, the user program 4 consists of command steps describing the machining to be carried out by the machine tool 1 . Alternatively, the instruction steps may also be machine-dependent or machine-independent.

[0039] The digital controller 2 executes a user program 4 . In the context of executing the user program 4 , the numerical control unit 2 progressively generates machine-related control commands for the machine tool 1 and controls the machine tool 1 accordingly. This takes place within the scope of the real-time kernel (NCK)5. The real-time kernel 5 includes a real-time runtime system 5' and control sof...

Abstract

The present invention relates to a simulation method for simulating a real controller of an industrial process, plant or machine and a simulation system for performing such a simulation method. Simulation methods for simulating real controllers (2) of industrial processes, facilities or machines should make it easier to draw errors that occur during the simulation. For this purpose, the invention proposes that the simulation system (7) stores the intermediate state during the simulation and equips the intermediate state with a time stamp, wherein a stored intermediate state can be reloaded into the simulation system (7) at a subsequent point in time And a simulation can be performed based on this intermediate state. Therefore, the simulation does not always have to start from the beginning of the control program to be simulated.

Description

technical field [0001] The present invention relates to a simulation method for simulating a real controller of an industrial process, facility or machine, wherein a control program for controlling an industrial process, facility or machine is preset for the simulation system, wherein the simulation system executes the control program control commands for a process, plant or machine by means of a simulation program, and wherein the simulation system derives desired actual values ​​of the process, plant or machine from a model of the process, plant or machine and takes into account the actual value. The invention also relates to a simulation system for carrying out such a simulation method. Background technique [0002] Machine tools are well known. They are controlled by digital controllers. The digital controller executes a user program (control program) consisting of instruction steps, e.g. subroutines according to DIN 66025 or DIN 66025+. The user program defines, for...
