Users can now use programs written in high-level languages such as C/CC+ with Simatic controllers. Siemens has developed the new CPU 1518 ODK advanced controller and the Simatic ODK 1500S engineering package for this purpose. With the Open Development Kit, the user creates his high-level language program and integrates it into the Step 7 program of the new controller, which is based on the most powerful CPU in the current Simatic S7-1500 controller range from Siemens.
