programs using a self-contained CAM system. ere are virtually no limits to data communication. XPanel focuses on the optimal control for workpiece machining with maximum productivity. But the operating system also provides a direct connection between the machine control and the operation's data collection group within the company. Besides job and setup information, the operator also receives drawings and quality requirements or even his/her own documents on the control panel screen. Xpanel thus creates the conditions for the use of Industry 4.0 that is increasingly being demanded across industries. Network-Integrated Control and a High-Res Touchscreen Before the idea of such a control system could be imple- mented in detail, basic conditions had to be created: Index had already made the step to a network-integrated control technology with the new C200 sl control generation, which has been on the market for more than a year and is now standard for all new Siemens-controlled Index machines. It is based on the Siemens 840D sl (solution line) control, drives, 1FT7 servomotors and the ET200S ProfiBus peripherals. Another fundamental component is the 18.5-inch touch-sensitive wide-screen monitor that does not require a Windows PC. e user interface works with a separate controller, running Index's software, among others. e new control panel concept of the C200 sl is a small revolution: It included not only an already familiar keyboard, but also many non-safety-related rotary and tip switches from the machine control panel directly on the touchscreen. is creates space for the 18.5-inch monitor with WXGA resolution (1,366 × 768 pixels), 16:9 aspect ratio and LED backlight with 300 cd/m² brightness. ese characteristics make it possible to use the monitor for high-resolution simulations on the machine itself. anks to the latest capacitive touch technology, the screen can be operated even with gloves. A touch is sufficient to activate the desired function. Because hardware elements are eliminated, the machine control panel located under the monitor has become significantly leaner and clearer. e remaining keys are provided with LED backlight and are protected against accidental operation. If they are operational in the current machine status and the associated movements are allowed, they are selectively backlit, while invalid keys remain dark. Flashing keys must be enabled by the operator to guide he or she and prevent errors. Multi-Functional Screen e touchscreen has a separate controller. For this mini- computer with an 8 GB memory card and USB port, Index developed its own software, which lays the functional :: User and machine documentation is embedded as background information in Xpanel when the machine is commissioned. Both operating and programming instructions as well as complete circuit and hydraulic diagrams are part of the startup package. Preparing for Industry 4.0 productionmachining.com :: 29
