SCADE for Industrial Machine Control
Liebherr is one of the world’s leading manufacturers of construction machinery and also a supplier of technically innovative user-oriented products and services in numerous other fields. Products produced by Liebherr include offshore, harbor and crawler cranes, excavators, dozers, wheel loaders and mining equipment.
Liebherr EMT decided to search for a unified embedded software solution to harmonize software platform and application development tools and processes. They recognized that necessary key elements of this solution were the proprietary PME platform, based on COTS real-time operating system, and a well-tailored software development process. Requirements also included the ability to reuse software modules, real time CAN protocol and most importantly, the solution had to meet safety requirements according to IEC 61508 SIL2.
Liebherr chose SCADE Suite as the standard software development environment for all design centers for earth moving machines in Germany, France and Austria because it is specifically designed for safety-critical projects, and because SCADE Suite handles all phases of the development cycle, from specification to implementation, test/verification and documentation. SCADE Suite allowed Liebherr developers to reuse existing software modules and generate highly optimized C code with good runtime performance. ANSYS solutions have vastly shortened development time during the test/verification stage of software development. SCADE with the PMElink plug-in enable them to tailor, maintain and parameterize SCADE-based applications directly in the field, even on top of a mining excavator in a South African Gold Mine.
