Overview Manuals Display & Keys DP & MPI Project Capacity Mounting & Backup

Features:

  • A 12-inch 1280 x 800 TFT combines 65,536-color touch operation with ten physical function keys.
  • PROFIBUS DP, MPI, and Modbus RTU communication use the shared RS485/RS422 interface.
  • Ten megabytes of user memory, USB media support, IP65 front protection, and WinCC Basic engineering support machine visualization.
Siemens 6AV2123-2MA03-0AX0 is a KTP1200 Basic DP key-and-touch panel for displaying process information and entering operator commands.

Its widescreen TFT, resistive touch layer, function keys, alarm resources, recipes, variables, and multilingual runtime provide the interface resources for a configured machine project.

The panel connects through PROFIBUS DP or MPI and requires the correct WinCC project, bus settings, termination, cabinet cutout, and front seal before commissioning.

The Siemens 6AV2123-2MA03-0AX0 SIMATIC HMI KTP1200 Basic DP Operator Panel may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Operator Interface Hardware

  • Screen: The 12-inch TFT presents 1280 x 800 pixels and 65,536 colors.
  • Touch layer: Analog-resistive input supports direct screen operation.
  • Function keys: Ten physical keys can be assigned to frequently used project actions.
  • Backlight: LED illumination supports the configured brightness and screen-saver strategy.

Serial Fieldbus Communication

  • Physical interface: The shared RS485/RS422 connection carries the configured network.
  • PROFIBUS DP: The panel can exchange visualization data with a compatible DP system.
  • MPI: MPI communication is available where the configured controller and network support it.
  • Commissioning check: Address, baud rate, cable, connector, and termination must match every node on the segment.

Visualization Resource Limits

  • User memory: Ten megabytes store the transferred operator project.
  • Screen resources: The panel supports as many as 250 configured process screens.
  • Variable resources: Up to 800 process variables can be assigned in the project.
  • Alarm and recipe resources: The configuration supports up to 1000 bit alarms and 50 recipes.

Cabinet Installation and Project Recovery

  • Front protection: Correct panel mounting and sealing provide IP65 protection at the front.
  • Rear protection: The IP20 rear must remain inside a suitable enclosure with the required clearances.
  • USB media: Supported storage media up to 16 GB can be used for documented backup and restore procedures.
  • Recovery preparation: Preserve the WinCC project, panel image, communication settings, recipes, and password records before replacement.
Description
Siemens 6AV2123-2MA03-0AX0 presents machine states and operator controls on a 12-inch 1280 x 800 TFT while retaining ten physical function keys for frequently used commands. The display supports 65,536 colors and analog-resistive touch input.

PROFIBUS DP or MPI communication connects 6AV2123-2MA03-0AX0 to the configured automation system through its shared RS485/RS422 interface. The project is engineered with WinCC Basic V13 or later and stored in 10 MB of user memory.

The front of 6AV2123-2MA03-0AX0 is rated IP65 while the rear is IP20, making cabinet cutout, sealing, grounding, and ventilation part of the installation design. USB media can be used for supported backup and restore tasks after the project, panel firmware, bus address, and termination arrangement are verified.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why might 6AV2123-2MA03-0AX0 show the project but not communicate with the PLC?
Check the 6AV2123-2MA03-0AX0 bus address, baud rate, protocol selection, connector wiring, termination, PLC station settings, and the communication connection configured in WinCC.
Can a project for another KTP1200 variant be transferred directly to 6AV2123-2MA03-0AX0?
Not without verification. The 6AV2123-2MA03-0AX0 is the Basic DP variant, so the target device, communication interface, panel image, key layout, and project version must match.
What should be backed up before replacing 6AV2123-2MA03-0AX0?
Save the WinCC source project, current 6AV2123-2MA03-0AX0 backup, panel image, recipes, communication parameters, user administration, and any site-specific runtime data that the procedure supports.
Why can touch alignment be inaccurate on 6AV2123-2MA03-0AX0?
For 6AV2123-2MA03-0AX0, clean the resistive surface correctly, run the documented calibration, check that the front is not mechanically stressed, and inspect the overlay for damage.
Does the IP65 rating of 6AV2123-2MA03-0AX0 apply to the rear of the panel?
No. 6AV2123-2MA03-0AX0 is IP65 at the properly installed front and IP20 at the rear, which must remain protected inside the cabinet.
What causes a blank screen after a project transfer to 6AV2123-2MA03-0AX0?
Check 24 V DC supply quality, display brightness, panel-image and WinCC version, transfer completion, startup settings, and whether 6AV2123-2MA03-0AX0 reports a boot or communication diagnostic.
