Today, Linux has become the most popular real-time operating system. Due to its deterministic hard real-time behavior, sophisticated development tools and broad hardware driver and software support, it is used by leading manufacturers of industrial controllers. Typical applications are PLC, Motion Control and Numeric Control systems with high real-time requirements.

Using the LxWin Hypervisor it is possible to run Windows and an extremely fast, embedded real-time Linux in parallel. Plenty of Linux drivers, e.g. for fieldbus controllers or GigE camera systems, communication stacks (EtherCAT, Profinet, OPC, OPC UA, TSN, ...) or complex software solutions like CNC controller or software PLCs can be used without any change under LxWin.
In case customer's current solution is split into 2 different parts using a Windows based GUI system and a Linux based controller, LxWin is the way to consolidate such solution on one single hardware. Eclipse or Microsoft Visual Studio (starting at VS 2015) can be used for software development.

EtherCAT® Network Configuration, Diagnosis, and Monitoring

EC-Engineer is a powerful software tool used for configuration, diagnosis, and monitoring of EtherCAT® networks. Using this single tool one can handle all required engineering and diagnosis tasks in a quick and comfortable way. The modern, clear and very intuitive user interface, which is also rarely using popup dialogs, is crucial for a smooth experience in configuring, diagnosing, and monitoring of EtherCAT® systems.

Using the EC-Engineer the EtherCAT configuration can be done "offline" in the lab/office or "online" when connected with the real EtherCAT network on the machine. It doesn't matter whether the EtherCAT slaves are connected with the local Windows PC where the EC-Engineer is running or with the control system where the control application's master stack is running. In either case the slaves and the network topology can easily be determined using the "Bus-Scan" feature. In case the slaves are connected with the Windows PC, the integrated Windows EtherCAT Master is able to run and verify the system. If the slaves are connected with the control system, the master stack running on the controller will take over communication and provide all services and information to the EC-Engineer which are needed for diagnosis.

General Features

• Configuration of multiple master systems within one project
• EtherCAT Slaves connected to the Windows PC
• EtherCAT Slaves connected to the control system
• Tree View and Topology View
• ESI and EMI Manager
• Multiple Languages
• Modern User Interface based on Microsoft WPF technology

Configuration Features

• Import ESI (EtherCAT Slave Information) files according to ETG.2000
• Export ENI-(EtherCAT Network Information) files according to ETG.2100
• Automatic determination of the connected slaves (bus scan)
• Slave device copy and paste including all parameters
• PDO selection and configuration
• Adjustment and appending of EtherCAT slave init commands
• Transparent integration of MDP (Modular Device Profile) Slaves
• Fixed memory layout of slaves or
• Distributed Clocks (DC) Settings
• Definition of "Hot Connect" groups

• Other Master and Slaves parameters

Diagnosis and Monitoring Features

• Master and Slave State (display and control)
• Process (I/O) data (display and control)
• ESC Register (read and write)

The acontis RTOSVisor solution is Type 1 Real-time Hypervisor that is an optional and independent enhancement of acontis' Type 2 Real-time Hypervisor solutions for Windows (LxWin and VxWin). This solution enables customers to fulfill demands for more sophisticated use cases. It is a perfect fit for Industrial Internet of Things (IIoT) devices, Edge Controllers, high-end Real-time hardware, and workload consolidation.

With acontis' industry-proven Real-time Hypervisor technology, multiple hard Real-time operating systems such as Real-time Linux and VxWorks can run natively. The solution incorporates KVM, which allows multiple standard operating systems like Windows and Linux (Ubuntu, Debian, Fedora, and many others) to operate simultaneously. KVM provides virtual hardware access and paravirtualization, which results in improved performance. KVM also supports hardware pass-through of PCI, USB, and VGA devices, ensuring the best possible performance.

Each guest OS is entirely independent and separate, which means that one OS can be restarted or shut down without affecting the others. This feature provides customers with the flexibility to manage their systems without any interruptions.

Run an EtherCAT Controller with a Simulated Network

EC-Simulator virtualizes EtherCAT networks by simulating the EtherCAT slave devices in order to run EtherCAT Master applications without real EtherCAT slave hardware devices available.
EtherCAT simulation is possible via a physical network adapter, or also virtually, to realize a completely simulated machine setup. Configuring the simulation instance is seamless using the ENI file of the real network.
With EC-Simulator it is possible to react to Process Data (PDOs), send and receive Service Data (SDOs), interact with the Slave Stack, and more. This is all possible to be programmed via the API available for C/C++ or .NET, enabling the connection of EtherCAT data to various other professional software tools for the imitation of real-world systems.
