# ISG - kernel

## Flexible, open and secure

ISG-kernel has been in use for more than 30 years. It is under continuous development and is used annually in over 15,000 control systems by leading manufacturers such as HOMAG, KUKA, Beckhoff and KEB.

In addition to its comprehensive functionality, ISG-kernel’s special features include its outstanding motion and velocity preparation and the architecture model on which the control software is based. This architecture is adaptable to the specific requirements of our customers and can be continuously extended to include new technologies and functions. Due to the functional integration of CNC, robotics and motion control (MC), the software is excellently suited for machine tools and robots, for the movement of complex kinematics and also for the PLC-oriented programming of movements using PLCopen function blocks.

## Technologies

The wide range of applications of ISG-kernel includes a wide diversity of technologies. Of course, ISG-kernel is used for traditional milling, grinding and turning applications. However, it also includes functions for laser or waterjet cutting, dispensing as well as wire and die-sinking EDM. You can also solve your handling and packaging tasks using a wide variety of kinematics.

## Functions

## Architecture model: Industry 4.0

- Universal axis swap concept with freely programmable axis swap between channels, axis swap look-ahead and cross-channel synchronisation via axis objects.
- It implements Industry 4.0 concepts through the decentralised distribution of control modules to multi-core systems.
- Dynamically configurable software toolbox (parallelisable for multi-core CPUs) permits continuous extension to include new technologies and functions.
- Continuity without breaks: machine tool - robot - PLCopen

## Industries and references

ISG-kernel is used in many sectors by large and medium-sized companies. Due to its open software architecture, ISG-kernel allows the control of machines and systems for almost all CNC, robotics and motion control (PLCopen) applications, irrespective of industry. We would be delighted to support you in your project.

Control manufacturers

Control manufacturers are faced with the challenge of continuously developing the functionality and performance of their controllers. The development of high-end functionalities (3D machining, kinematic transformations, HSC, multi-channel functionality, compensations, collision monitoring, etc.) ties up capacities and requires in-depth know-how. ISG-kernel includes many of these functionalities and, due to its open architecture and compatibility, extends existing control technology to obtain a powerful complete system within a very short time.

Control manufacturers

Machine manufacturers

Many machine manufacturers decide to develop their own machine control system, but then they face similar challenges to control system manufacturers. Highly complex functionalities are required within the shortest possible time but they cannot be implemented in-house for various reasons. Other machine manufacturers use controllers available on the market that require adaptations to the existing standard control environment. ISG-kernel optimally supports component-based, open control technology. It provides a powerful, individual control solution that can be assembled from in-house and market-sourced components, e.g. in the fields of manufacturing and handling, to solve a wide variety of motion tasks consistently and reliably.

Machine manufacturers

Plant manufacturers

The task of plant manufacturers is to design a plant from many individual components in which all components interact efficiently and safely. This requires a wide variety of controllers and a large number of axes that must be combined, controlled and monitored. ISG-kernel provides continuous real-time control for simple and complex motion sequences within the entire system. The number of axes is open upwards. In addition, a wide of range of interfaces to user interfaces, drives and PLCs allows numerous intervention options in the process. This achieves high availability and fault situations are safely managed.

KUKA AG

As one of the world's leading suppliers of intelligent automation solutions, KUKA offers its customers everything from a single source: from the main component, i.e. the robot, through to the cell and fully automated plants. By fully integrating ISG-kernel into the KRC robot controller, KUKA succeeded in expanding the range of functions with high-end CNC and motion control functions with the options "KUKA.CNC" and "KUKA.PLC Multiprog MCFB". KUKA.CNC provides an NC control kernel fully integrated in a KRC, offering the possibility to run NC programs directly on the KUKA controller. NC programs, programmed offline using a CAD/CAM system, can be processed and run with the robot without prior conversion to KRL (KUKA Robot Language) programs.
