Siemens 6AV2128-3XB27-0AX0 SIMATIC HMI MTP2200 Unified Comfort PRO 21.5-Inch PROFINET HMI Operator Panel

The Siemens 6AV2128-3XB27-0AX0 SIMATIC HMI MTP2200 Unified Comfort PRO is a 21.5-inch widescreen multi-touch panel for support-arm mounting, built for WinCC Unified V18 and higher. It runs an X86 processor with 24 V DC supply, PROFINET with an integrated 2-port switch, and IP65 protection on both front and rear for washdown or dusty cabinet environments requiring a sealed operator interface.

Selection Notes

This is the support-arm variant (flange on top, not expandable) rather than a panel-mount frame, so it fits swing-arm operator stations and console mounts instead of a door cutout. The integrated 2-port PROFINET switch lets it daisy-chain to a downstream PLC or I/O station without a separate switch. IP65 on both front and rear means the enclosure rating holds regardless of orientation, which matters on an arm mount where the rear is exposed. Configuration requires WinCC Unified Comfort Engineering V18 or higher in TIA Portal; older WinCC Comfort-only projects are not directly compatible with this panel.

Applications

Fits arm-mounted operator stations on production lines, central SCADA-style overview panels, and washdown-adjacent machine control where a sealed front and rear matter. The 8,000-variable capacity, 750 recipe types, and 32-language runtime suit larger WinCC Unified projects that need process value display, alarm management, and recipe handling on one 21.5-inch touchscreen.
