SIMATIC HMI MTP400, Unified Basic Panel, touch operation, 4 widescreen TFT displays, 16 million colors, PROFINET interface, configurable from WinCC Unified Basic V18 Upd. 3, contains open source software which is provided free of charge, see enclosed Blu-Ray SIMATIC HMI Unified Basic Panels enable innovative operating concepts based on the new SIMATIC WinCC Unified visualization software. All devices, in sizes from 4 to 12 inches, offer the same number of interfaces and maximum operating comfort thanks to modern multi-touch technology. The new hardware also offers significantly more power for implementing the visualization. The system limits have been greatly increased, in some cases even doubled. This enables much larger applications to be implemented on a panel system than before. To guarantee the IT security of the devices, Siemens uses a proprietary operating system and enables the user to deactivate functions or interfaces that are not required.
