The Sinumerik CNC Blackline touch panels are available with a side screen enhancement. This development enables users to customize the CNC panel, laying out the operator panel in real time, using a drag-and-drop technology. Screens can be customized to view documents, camera projections, Web server access information, access protection data for IT security protocols and even user administration. The side screen achieves features and functionality such as the ongoing checking of machine tool status, quicker and easier navigation, elimination of mechanical keys and keyboards additions. The side screen can be opened or closed on either the left or right side of the master operator panel.
