ProfiNET Device - Real-time Simulation for Windows

With the ProfiNET Device Stack for Windows, a complete system can be simulated at real-time with a PC. The stack offers the possibility to read in existing GSDML files of real devices and to configure them for the simulation. So the simulated devices behave like in the real world. In combination with the "X - Realtime Engine" from SYBERA, the realtime simulation behaves like the real system. The device simulation is carried out directly from the PC using standard Ethernet adapters. The physical connection to the PLC is made using commercially available INTEL or REALTEK PCI (e) adapters. A corresponding PCMCIA or ExpressCard (PDF) adapter is also possible. This means that no additional hardware is required and there is no need for separate ProfiNET hardware. The basis of the programming library is the ProfiNET Device Stack with the "X - Realtime" technology. The software runs on Windows and enables the simulation of several ProfiNET devices simultaneously at real-time. Depending on the PC hardware and application, telegram update times of up to 250 μsec can be implemented.

ProfiNET Device - Functionality

With the integrated station management of the ProfiNET device stack, the devices can be managed and operated almost completely implicitly. Each individual function step (ProfiNET service) can also be controlled in a targeted manner. In addition, SYBERA has developed the comprehensive test software PNIOVERIFY. This software enables the developer to test the simulated ProfiNET devices and carry out the parameterization. The developer is guided interactively through the individual function groups and states. All information is visualized in detail.

ProfiNET Device - Technology

Here, not only the sending and receiving of industrial Ethernet protocols according to the ProfiNET specification is realized at real-time. The interface also enables the functional processing of the ProfiNET telegrams in a separate real-time task. The system is based on 4 real-time tasks: sending and receiving Ethernet frames, processing user data and error handling. The tasks are functionally synchronized via a STATE machine. A real-time task detects frame errors and hardware latencies. It is also checked whether a response telegram was received for a sent ProfiNET telegram (e.g. in the event of a timeout), whether the working counter of the response telegram has been increased and whether the index fields of the send and receive telegrams match. With a frame filter, the ProfiNET telegrams are separated from the Ethernet frame at real-time and transmitted to a telegram stack. The developer has the option of implementing the functional processing (e.g. Realtime Level2) in a real-time task at the system or application level.

ProfiNET - Training

In order to be able to use fieldbus communication efficiently, Sybera offers the training "ProfiNET Development" . In our training, we impart knowledge in a neutral and product-independent manner. The course provides a comprehensive insight into ProfiNET technology using examples and practical exercises. The focus of the training is on ProfiNET specification, topology, protocol management, Profinet services, communication and application relationships, acyclic and cyclical protocols, ProfiNET RT and IRT communication, alarm handling, project planning, GSDML device description and configuration. The participants of the training receive detailed background information about ProfiNET for daily use and consolidate their knowledge with Wireshark analyzes. Different training devices are available for the examples. The participants of the training will also be able to independently configure, program and analyze ProfiNET projects. The training is aimed at all users, developers and service technicians.
