MEASUREMENT AND CONTROL

MEASUREMENT AND CONTROL 01 02 03 04 01 Instead of a real-time core embedded in Windows, the new architecture with parallel operation permits maximum availability of the software controller 02 The integrated webserver allows remote access to the CPU operator panel, the diagnostic buffer, and further information 03 The Simatic ET 200SP open controller combines a PC-based controller with the design and modular expandability of the ET 200SP I/O system 04 The CPU Panel is a Windows application and similar to the other S7-1500 CPUs Secure, simple and open communication The engineering and complete configuration of the software controller takes place in the TIA Portal engineering framework. This means that no settings are necessary within Windows. Despite this independence of the software controller from Windows, data can still be exchanged between the two sides. On the one hand, S7 blocks permit direct TCP/ IP communication. On the other hand, the ODK 1500S open development kits enable high-level languages to be integrated into the Step 7 user program. The Eclipse development environment for programs with real-time capability is also included in the scope of delivery. Furthermore, Visual Studio can also be used for Windows applications. The Open Development Kit independently creates the required S7 blocks, which can then be integrated into the Step 7 program in the TIA Portal without the need for high-level languages. The advantage is that the machine manufacturer can continue to work in the familiar Step 7 programming languages. Thus, on the one hand, high-level language code that has already been generated can easily be reused and, on the other hand, data can be exchanged with Windows programs such as image processing software. With the aid of the TIA Portal, the entire user program can be protected against unauthorized copying and manipulation. The integrated know-how protection can be activated by a mouse click. The user program is thus linked with the serial number of the hardware and can only be executed on the industrial PC designated for this purpose. This effectively prevents any unauthorized copies and also means that the spare parts business remains within the value creation chain of the machine builder. PC-based controllers augment the Simatic S7 portfolio for special requirements. With the new architecture, the software controller and Windows are operated in parallel directly on the hardware. This means that Windows failures no longer have any effect on the availability of the controller. For the first time, the openness of the PC-based automation engineering no longer precludes greater system availability. The Simatic S7-1500 software controller now provides a PCbased controller that is particularly suitable for special machine manufacturing due to its high level of availability and openness for complex tasks. www.siemens.com 20 MDA Technologies 3/2015
