The Siemens 6AV2128-3GB36-0AX1 is a SIMATIC MTP700 Unified Comfort HMI operator panel, a neutral 7-inch multi-touch panel configurable from WinCC Unified Comfort V16. It connects over PROFINET with two Ethernet ports plus an independent port, offers four USB 3.1 Gen 1 ports and two SD card slots, runs on 24V DC, and carries IP65 protection at the front for panel or cabinet-door mounting.
The MTP700's four USB 3.1 Gen 1 ports and dual-Ethernet-plus-independent-port interface are a step up from the Comfort-series TP/KP panels' USB 2.0 and shared-switch Ethernet, reflecting the move to WinCC Unified engineering rather than classic WinCC Comfort or Advanced. The neutral bezel variant carries no application-specific enclosure treatment, so it is the base choice unless the application needs the hygienic, stainless-steel MTP700 variant for washdown or food-contact areas. Multi-touch support, versus single-touch on the Comfort TP-series, allows pinch and zoom gestures in Unified faceplates, relevant where the project uses Unified's trend or diagram controls.
Fits new machine builds standardizing on WinCC Unified rather than classic Comfort or Advanced engineering, where the four USB 3.1 ports support faster recipe or log transfer to external storage than the older USB 2.0 Comfort panels.
