The OPENcontrol product family is an highly scalable CNC system based on several powerful hardware platforms. The same software, real-time and HMI, works on the whole OPENcontrol range, allowing to choose the model with the most suitable characteristics for the application, simplifying this way the development and the maintenance of machines with different complexity levels. OPENcontrol performances increase with the models named OPEN-M, OPEN-XL and OPEN-XLi, the latter one being able to manage up to 24 process, 12 simultaneously interpolated axes per process and a total number of 64 axes. OPEN-M and OPEN-XL, respectively equipped with Intel Celeron-M 2.0 GHz CPU and Core 2 Duo 2.26 GHz, are suitable for the development of complex applications, having a computing power fitting the multi-process working centers with several axes. For both models, the SW structure with dual operating system Windows CE and Windows 7 (WES7) is available for the simultaneous execution, on the same hardware, of both CNC real time applications and market software for Windows. Thanks to the i5 CPU, OPEN-XLi is the solution that best fits working centers requiring the highest performances. OPEN-M, OPEN/XL and OPEN-XLi can be completed with OSAI Operator Panels or with simple touch screen monitors, with high performances servo-drives and servo-motors driven by EtherCAT bus and with a complete line of modular I/OS.
