Overview
- For developing dynamically loadable function libraries for the S7-1500 Software Controllers and S7-1500 Advanced Controllers CPU 1518 MFP and PLCSIM Advanced:
- Implementation of function libraries for the SIMATIC S7-1500 Software Controllers that are executed under Windows with the high-level languages C/C++, C# and VB
- Implementation of function libraries for the PLCSIM Advanced that are executed under Windows with the high-level languages C/C++
- Implementation of function libraries that are executed in real-time in the context of the user program of the CPU with the high-level language C++
- Implementation of applications for the C++ runtime of the CPU 1518 MFP
- “Eclipse” development environment for real-time function libraries in the CPU user program and applications for the C++ runtime in the scope of delivery.
- Development of library functions under Windows with MS Visual Studio (optional)
- Easy introduction to development by using basic projects via templates
- Automatic creation of function blocks for calling the library functions
- Simple integration of the function blocks into STEP 7 by importing.
- Simple use of the library functions in the PLC without specific high-level language know-how.
Licensing
- ODK 1500S is supplied with a floating license. The floating license allows installation of the software on any number of computers. The number of existing licenses determines the number of computers on which the software can be used simultaneously.
- The integrated development environment Eclipse, required for developing real-time libraries, is included in the scope of supply of ODK 1500S as well as templates for Visual Studio.
- SIMATIC ODK 1500S is available as a standalone product or in a bundle with SIMATIC Target 1500S™ for Simulink®.
You can find more information on the Software Update Service, license types, Online Software Delivery and handling your SW licenses with the Automation License Manager under this link.
Application
Typical applications which are developed with the SIMATIC ODK 1500S:
- Windows function libraries (S7-1500 Software Controller):
- Interfacing to databases

- Development with the high-level language C++ with the Eclipse development environment (included in the scope of delivery)
Function
The SIMATIC ODK 1500S supports the development of dynamically loadable function libraries that can be called up directly from the user program of the S7-1500 Software Controller, from the S7-1500 Advanced Controller CPU 1518 MFP or from the PLCSIM Advanced. Loadable libraries can be generated here both under Windows (DLL) and in the real-time context (SO – shared object) of the ODK-capable SIMATIC controllers.
Applications can also be developed that can be executed parallel to the user program on the CPU 1518 MFP.
Generation of loadable function libraries
Generation of loadable function libraries takes place with Microsoft Visual C++ for function libraries under Windows and with Eclipse (included in the scope of delivery) for real-time function libraries that are executed in the user program of the CPU. By creating a project with the help of a pre-defined template, users can begin immediately with the definition and implementation of the functions.
On completion of a function library, function blocks are available that can be integrated directly into STEP 7 and used for loading and executing the functions from the control program.
Following completion, the function libraries themselves are available as DLL (Windows function libraries) or SO file (shared object – real-time function libraries). Real-time function libraries are loaded into the load memory of the controller via its web server so that they can also be loaded and executed independently of Windows.
For Windows libraries, the complete function range can be used for Windows DLLs. Development is carried out with Visual Studio.
The integrated development environment Eclipse, required for developing real-time libraries, is included in the scope of delivery of ODK 1500S.
Testing function libraries
Windows function libraries can be fully debugged with Visual Studio. Thanks to the asynchronous execution of functions under Windows, the real-time characteristics of the Software Controller are not impaired even if single-step or breakpoints are used.
A powerful trace concept is available for real-time function libraries in the context of the user program, as single-step processing or breakpoints are not feasible under real-time conditions. To verify the code with single-step processing or breakpoints despite this, the functions of a real-time library can be called up and tested within a test environment on the development PC. In addition, a memory map of the real-time function library is generated when software exceptions occur. This can be used to determine the cause of the exception in the Eclipse development environment.
Creation and testing of applications for the C++ runtime of the CPU 1518 MFP
Creation of applications for the C++ runtime of the CPU 1518 MFP with Eclipse. The applications are transferred directly from the development environment to the target device during development, and started and debugged in the normal way. For automatic operation, the application can be started with a startup script.
