ISG-virtuos: Digital twins from virtual components in deterministic real time
ISG-virtuos is an open, cross-company simulation platform, with which complete production systems including all components (controls, robots, material flow etc.) can be checked and optimized in deterministic real time.
Open simulation platform
in deterministic real time
Easy creation of own components
using SDK C++
Consistent added value in engineering
through reusable components
Consistent concepts for different simulation applications
(„Co-simulation“)
3D configuration of digital twins from
cross-vendor component libraries
Scalable solutions up to
HiLS simulations for complete factories
The simulations are created from virtual components, which - stored in appropriate libraries - can be reused and exchanged at any time. This means that virtual systems are not created anew each time, but are configured by simply replacing the components. This process can also be completely automated.
ISG-virtuos covers all simulation areas from MiLS over SiLS to Hardware-in-the-Loop simulation. During system testing, deterministic control real-time with guaranteed response times of e.g. 1 ms is achieved by directly connecting real control systems via common field buses and the use of real-time operating systems.
Virtual commissioning (VIBN) and simulation-based engineering
In order to put machines and plants virtually into operation before the real assembly and commissioning, a digital image of the real components and the system behavior is created using the original engineering data. With the help of ISG-virtuos, automation scenarios including fault situation and safety are simulated in advance. The complex interaction of mechanics, electrics and control can thus be tested and optimized at an early stage. The software is ready for use even before the real commissioning.
In addition to the virtual commissioning, the digital twin can be used throughout the entire life cycle of the system - without interfering with ongoing production.
-
How do different component parameters influence the machine?
-
How stable does the system run when an error occurs?
-
By which factor can the production speed be increased without loss of quality?
Questions like these are easy to answer: Using real machining and production data, module, integration and system tests can be carried out reproducibly at any time. With the help of the test automation tool ISG-dirigent also automated and integrable into the requirements management.
Shortening of the real commissioning and
total project duration

Maximum reduction of
production ramp-up
Training on the real control
without downtime and production pressure
Automatic connection of TwinCAT to ISG-virtuos
One of the absolute unique selling points of ISG-virtuos is the mapping of all real fieldbus components as real fieldbus participants in deterministic real-time on EtherCAT including safety. From the control's point of view, there is no difference between real and virtual components, which means that mixed operation is also possible. The structure of the fieldbus connection is fully automated by using original project planning data from TwinCAT.
TwinStore: The Online Store for simulation models for the virtual commissioning
The TwinStore, which can be seamlessly integrated into the runtime environment of ISG-virtuos, provides component and plant suppliers as well as plant operators with a digital exchange platform for comprehensive virtual design, protection and commissioning. Component manufacturers store the digital images of their real components there, which correspond to the real components in terms of interfaces, parameters and essential behavioural characteristics. Furthermore, simulation specialists offer libraries for mapping specific, highly specialized (process) simulations.

ISG-dirigent: Model-based test automation with digital twins
Thanks to digital twins, machines and plants can now be put into virtual operation long before they are actually completed. In order to achieve a high reliability and robustness of the control software, its behavior must be tested both in normal and in the much larger number of irregular operating cases.
ISG-dirigent is the first commercially available tool for automated testing of control software, which executes once created test sequences independently and reproducibly at any time.
The test modules necessary for the creation of
the sequences are characterized by their intuitive graphical
modeling. They represent the modularity of machines and systems and
can be used in different development phases. The extensive
collection of block libraries for frequently used control
systems can be easily extended if required. Familiarization with
the tool is easy and can be done without special
programming knowledge. This allows users to concentrate on
creating test sequences and the necessary test blocks right from
the start.
Benefits of model-based test automation
Targeted error diagnosis and (certifiable) documentation thanks
to
reproducible test execution with detailed result logging
Increase of reliability and robustness of the control software
and thus
the quality of the entire machine or plant
Execution of frequently repeated test sequences
even outside working hours
Time and cost savings with increasing scope and complexity of
control software
and number of iterations
Exemplary connection to TwinCAT CNC
The test automation tool is connected via the ADS interface from Beckhoff. On this basis, ISG-dirigent provides an extensive block library for reading and writing control parameters and for convenient, automated "operation" of TwinCAT CNC.
ISG Industrielle Steuerungstechnik GmbH: Control and simulation technology from one source
ISG-virtuos was developed by specialists of the Stuttgart company ISG Industrielle Steuerungstechnik GmbH. With a team of currently approx. 60 colleagues ISG has been developing innovative software solutions and technologies in the field of control and simulation technology for mechanical and plant engineering and other industries since 1987.
Based on the products ISG-kernel for CNC, MC and RC control and ISG-virtuos for the simulation of machines and plants in deterministic real time, ISG also offers tailor-made customer solutions as well as products and services that enable new business models and generate significant added value. ISG-dirigent, the first commercial tool for test automation of control software, has recently been added to the successful ISG portfolio.
Since the market launch of ISG-virtuos 2005, the simulation solution has been expanded in close cooperation with leading users from various branches of plant and mechanical engineering to a simulation platform that has not met any application limits so far. Users benefit not only from the functionality and performance of the test automation tool, but also from the many years of practical experience and great innovative power of our development team as well as the partnership-based cooperation.
In addition to companies from the automotive and supplier industry, especially medium-sized companies from plant and mechanical engineering of different industries as well as companies in the field of automation rely on software from ISG.
We believe that our many years of expertise, enthusiasm for what we do, state-of-the-art technical equipment and our competence, reliability and flexibility speak for us. Our customers, some of whom we have been working with for over 25 years, are also convinced of this.
