What Is the SIMATIC HMI KTP400 Basic 2nd Generation 4-inch Key and Touch Panel PROFINET (6AV2123-2DB03-0AX0)?
The SIMATIC HMI KTP400 Basic 2nd Generation 4-inch Key and Touch Panel PROFINET is an entry-level operator panel in the 2nd Generation Basic Panels family. A resistive touch screen plus four function keys gives operators tactile control even with gloves, while the 4-inch widescreen TFT handles essential visualization in a compact footprint.
Key and touch operation in one panel
The touch screen handles navigation and parameter input; the four function keys are typically assigned to frequent actions such as start/stop or acknowledge. This dual-operation layout suits small machines, cabinet doors and OEM equipment where space is limited and reliable tactile feedback matters.
PROFINET connectivity
A single PROFINET interface (RJ45) links the panel to SIMATIC S7 PLCs over industrial Ethernet. Projects are created in the TIA Portal with WinCC Basic / STEP 7 Basic V13 or higher.
2nd Generation hardware
Versus the first Basic Panel generation, this 2nd Generation adds a widescreen 16:9 display and higher performance; the -03 suffix marks the current hardware revision of the KTP400 Basic PN.

Frequently Asked Questions
What is 6AV2123-2DB03-0AX0?
It is the SIMATIC HMI KTP400 Basic 2nd Generation 4-inch Key and Touch Panel PROFINET — a 4-inch widescreen TFT operator panel in the 2nd Generation Basic Panels family, with touch plus 4 function keys, a PROFINET interface, configured via WinCC Basic / STEP 7 Basic V13+ in the TIA Portal.
What is the difference between this panel and the first-generation KTP400 Basic?
The 2nd Generation Basic Panels use a widescreen 16:9 TFT display and updated hardware. The -03 suffix in 6AV2123-2DB03-0AX0 marks the current hardware revision of the KTP400 Basic PN.
Which PLCs can it connect to?
It connects to Siemens S7 PLCs over PROFINET (industrial Ethernet, RJ45), for example S7-1200 and other PROFINET-capable controllers in the SIMATIC family.
Which software do I need to configure it?
Projects are engineered in the TIA Portal with WinCC Basic V13 / STEP 7 Basic V13 or a later version. The engineering software runs on your PC — no runtime licence is required on the panel.
Does it have physical buttons or only a touch screen?
Both. It combines an analog-resistive touch screen with 4 configurable physical function keys, which helps in gloved operation and for actions that need tactile feedback.
What display does it have?
A 4-inch widescreen TFT with 480 × 272 pixels and 65,536 colors — enough for clear basic process visualization in a compact 4-inch footprint.
What power supply does it need?
24 V DC with a permissible range of 19.2 – 28.8 V DC and typical power consumption of about 3 W.
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 with vertical installation.
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.
How do I get a quote?
Email sales@can-electric.com with the order number, the condition you need and the delivery country; we confirm availability and terms per order and quote in USD.
How is it shipped?
From Hong Kong via DHL worldwide. Packaging, lead time and terms are confirmed on each quote before you order.
