For HMI tasks in the upper performance range, the 370 series offers three devices with touchscreen operation and one model with membrane keypad. The Windows CE-based devices feature 12 MB of application memory and high-contrast TFT displays with resolutions from 800 x 600 to 1280 x 1024 pixels.
For the operation with WinCC flexible options, 12 MB of supplemental memory is available. All devices possess a battery-less non-volatile alarm buffer and additional non-volatile memory for software-PLC data.
Commensurate with the more demanding application profile, the devices offer a wide range of interfaces, the option of using scripts and archives, and generally larger quantity structures. 16 online-switchable languages are other attributes of this performance class
In addition to WinCC flexible Runtime, the Microsoft Media Player, Microsoft  Internet Explorer for Pocket PCs and Microsoft Viewer (Word, Excel and PDF) are included in the delivery scope.

All MP 377 models can be used as platform for the software-PLC WinAC MP. The software-PLC SIMATIC WinAC MP 377 offers a level of performance similar to that of a CPU 317 of the S7-300 system. As complete solution comprised of Multi Panel and WinAC MP option, the system provides maximum performance with additional price savings.
