Embodiment Construction

[0042] To illustrate the invention, it is assumed, for example, that a process to be simulated for decelerating a drive of a production machine tool is used. In this case, for normal implementation, the drive should be operated at a predeterminable and adjustable speed of rotation, and after shifting into a standstill sequence, the speed should be reduced according to the selected stop mode. When simulating such a process, a plurality of working steps which take place here can be simulated and matched to each other. The simulation of the mechanical deceleration sequence and possible user inputs as well as interventions in the deceleration process triggered by motion control is taken into account. For example, three simulations are generated for this case, for the controller, for the drive and for the mechanical action. The simulation of the interaction is to be carried out in such a way that there is synchronization between them. Sub-simulations can then access real-time dat...

Abstract

A method for synchronizing a plurality of simulations executed by respective simulation programs, an associated computer readable storage medium and an associated coordination unit, wherein a plurality of simulations executed by respective simulation programs are synchronized, and wherein the following steps are performed by a coordination unit, i.e., determination of respective status messages ofthe simulation programs for the completed run through a given cycle, where for each simulation an associated cycle is established by a respective sequence via the respective simulation program of logic steps to be executed, and where outputting in each case of a synchronization message to one or more of the simulation programs, if the respective status messages of the plurality of simulations arepresent, such that each synchronization message triggers a start of a following cycle of the respective simulation program.

Description

technical field [0001] The invention relates to a method for synchronizing a plurality of simulations carried out by individual simulation programs, an associated computer-readable storage medium on which a computer program product is installed, and an associated coordination unit. Background technique [0002] In industrial automation, for example in industrial manufacturing, it is important to simulate processes. Manufacturing step sequences or processes or transport steps or the start-up of machines or the execution of production steps are simulated in order to be able to determine in a virtual environment whether unexpected faults or reactions or symptoms occur. A virtual simulation of the process is carried out using the results of usually several simulations. This virtualization of individual processes in an industrial environment simplifies planning and enables early detection of incorrect settings, incorrect parameterisation, incorrect wiring or incorrect design. I...
