Selection Notes

The 4.3-inch MTP400 is the entry size in the Unified Basic line, aimed at panels where a compact touch interface is enough and the single PROFINET port handles both engineering access and controller communication. Configuration requires WinCC Unified Basic Engineering from TIA Portal V18 Update 3 onward, so it is not backward-compatible with older WinCC Comfort/Advanced projects the way legacy Comfort panels are. Pick a larger Unified Basic or Unified Comfort panel instead when the application needs more screen real estate or a second Ethernet port for network segregation.

Applications

Fits compact machine control stations, OEM equipment front panels, and skid-mounted process units where a single-page or few-page operator interface over PROFINET is sufficient.
