Simatic Controllers are Now Using High-level Language Programs

Siemens Industry, Inc.

Simatic ControllersNuremberg - Today, programs written in high-level languages, such as C/CC+, are used with Simatic controllers. Siemens has developed the new CPU 1518 ODK advanced controller and the Simatic ODK 1500S engineering package for this purpose.

The user generates his high-level language program with the Open Development Kit, and integrates it into the Step 7 program of the new controller, which is based on the currently most powerful CPU in the latest range of Simatic S7-1500 controllers. The new range allows existing technological know-how, such as algorithms written in C/C++, to be combined with the high-end controller technology from Siemens. The Simatic ODK 1500S engineering package helps the user to develop C/C++ applications. The package also includes the Eclipse open program development environment for creating real-time applications, such as control functions and complex mathematical algorithms. The Step 7 blocks for Simatic controllers are generated automatically, which significantly simplifies the configuration of the controller. The high-level language programs are then called from the control program of the CPU. Ready-made function libraries are already available for applications such as wind power generation.

The Simatic Step 7 Target 1500S engineering package and the CPU 1518 ODK give users, for the first time, the capability of integrating complex Simulink models into the control program of a Simatic S7-1500 controller. This takes advantage of the benefits of model-based development with Simulink directly on an S7-1500 controller.

Background information
Siemens offers the right controller for an extremely wide range of automation requirements. The scalable Simatic range of controllers comprises basic, advanced, distributed and software controllers, all with the same range of functions. The S7-1200 basic controllers are used for compact automation solutions, and the S7-1500 advanced controllers for complex tasks, while the ET 200SP controllers are suitable for distributed applications, and the software controllers for PC-based applications.
