What Is the SIMATIC HMI MTP400 Unified Basic Panel 4-inch Touch Panel PROFINET (6AV2123-3DB32-0AW0)?
The SIMATIC HMI MTP400 Unified Basic Panel 4-inch Touch Panel PROFINET is the smallest member of the SIMATIC HMI Unified Basic Panels family. It brings the SIMATIC WinCC Unified system — with web-based remote access, JavaScript support and SVG graphics — to an entry-level, price-sensitive 4-inch panel for machine-level visualization.
Multi-touch, no function keys
A capacitive glass screen supports two-hand multi-touch and gestures such as pan and zoom. There are no physical function keys: all input is on-screen, which suits compact machines, cabinet doors and operator stations where a clean, sealed front matters.
PROFINET connectivity
An industrial Ethernet / PROFINET (RJ-45) port links the panel to SIMATIC S7 PLCs, and two USB 2.0 ports handle project transfer, data archiving and peripherals such as barcode readers. An integrated web client allows operation and monitoring from any modern HTML5 browser at no extra licence cost.
Engineered with WinCC Unified Basic
This panel is configured with WinCC Unified Basic V18 Update 3 or higher in the TIA Portal — not with the older WinCC Basic V13 used by the 2nd Generation Basic Panels. Check your TIA Portal version before ordering if you are migrating an existing project.

Compatibility and How to Order
Engineering requires TIA Portal with WinCC Unified Basic V18 Update 3 or higher — this panel is not configured with the older WinCC Basic V13 used by the 2nd Generation Basic Panels. Over PROFINET it couples to SIMATIC S7-1200, S7-1500 and S7-300/400 controllers, and it also supports OPC UA client connections to third-party devices. For cabinet-door mounting, check the cut-out dimensions in the current Siemens data sheet before machining the door. If your project still runs on WinCC Basic V13, consider a 2nd Generation Basic Panel instead (for example 6AV2123-2DB03-0AX0).
Typical uses
- Compact machine HMI where space is tight: small packaging, labeling and assembly equipment.
- Cost-sensitive visualization that still needs web-based remote monitoring.
- OEM equipment built on the WinCC Unified platform with S7-1200 / S7-1500 controllers.
How to order
- Send the order number 6AV2123-3DB32-0AW0 and delivery country to sales@can-electric.com.
- Tell us the condition you need (new or new-surplus) — stock state is stated on the quote.

Frequently Asked Questions
What is 6AV2123-3DB32-0AW0?
It is the SIMATIC HMI MTP400 Unified Basic Panel 4-inch Touch Panel PROFINET — a 4-inch widescreen TFT operator panel in the Unified Basic Panels family, with capacitive multi-touch, a PROFINET (RJ-45) interface, two USB ports and an integrated web client, engineered in the TIA Portal with WinCC Unified Basic V18 Update 3 or higher.
Is this a Unified Basic Panel or a 2nd Generation Basic Panel?
It is a Unified Basic Panel (6AV2123-3DB32-0AW0). It is engineered with WinCC Unified Basic V18 Update 3 or higher and displays 16.7 million colors, whereas the 2nd Generation Basic Panels use the older WinCC Basic V13 and 65,536 colors. The two families are not project-compatible without migration.
Which software do I need to configure it?
You need the TIA Portal with WinCC Unified Basic V18 Update 3 or higher. It is not configured with WinCC Basic V13 — check your TIA Portal version before you order.
Does it have physical function keys?
No. It is a pure touch panel: a capacitive glass screen with multi-touch and gesture support (pan and zoom). All operator input happens on screen.
How many colors does the display show?
16,777,216 colors (16.7 million) — far more than the 65,536 colors of the 2nd Generation Basic Panels.
What display does it have?

Which PLCs can it connect to?
Over PROFINET it couples to SIMATIC S7-1200, S7-1500 and S7-300/400 controllers, and it supports OPC UA client connections to third-party devices.
Can I access the panel remotely?
Yes — every Unified Basic Panel includes an integrated web client, so you can operate and monitor it from any modern HTML5-capable browser at no extra licence cost.
What power supply does it need?
24 V DC with a permissible range of 19.2 – 28.8 V DC.
Is it suitable for harsh environments?
The front face is rated IP65 (dust and water jet resistant) for cabinet-door mounting; the rear is IP20. Operating temperature is 0 °C to +50 °C.
Is the panel genuine and new?
We supply genuine Siemens hardware sourced through established channels. Condition (new or new-surplus) is stated on every quote, and units are inspected before dispatch.
Is CAN Electric an authorized Siemens distributor?
No — we are an independent channel trader, not Siemens. We source genuine Siemens products through Siemens-authorized distribution partners and confirm condition and delivery on your quote.
