Features:

  • 6AV2124-1QC02-0AX0 combines a 15.4-inch widescreen display with a dedicated key-operated front.
  • Separate PROFIBUS, switched PROFINET, and Gigabit Ethernet connections divide controller traffic from higher-level access.
  • Application, recipe, data-card, and system-card storage are assigned to distinct memory areas.
The Siemens 6AV2124-1QC02-0AX0 converts configured process values into operator screens and returns key commands to the automation system.

Thirty-six function keys give 6AV2124-1QC02-0AX0 a fixed physical command layer in addition to the graphical HMI project.

A 24 V DC cabinet supply, project memory, and the selected controller network complete the operating path around 6AV2124-1QC02-0AX0.

The Siemens 6AV2124-1QC02-0AX0 KP1500 Comfort Key HMI Panel may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6AV2124-1QC02-0AX0 KP1500 Comfort Key HMI Panel Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

From Physical Key to Controller Data

  • Front-panel role: Thirty-six function keys give the operator a fixed command surface alongside the graphical process display
  • Site identification: Replaceable labeling strips let each configured key be named for the machine function it controls
  • Direct-key route: Selected commands can bypass normal tag processing and enter the controller as direct-key data over the configured fieldbus
  • I/O image: The documented five input bytes and five output bytes keep the direct-key exchange separate from ordinary visualization variables

Why the Panel Uses Different Memory Areas

  • Runtime project: Screens, tags, alarms, and other HMI objects remain in the internal application area
  • Recipe records: A dedicated allocation keeps recipe data from consuming the full project-memory space
  • Operational files: The MMC/SD combination slot carries logs, recipes, and other removable runtime information
  • Service function: The independent system-card slot supports panel system and automatic service operations rather than ordinary process records
  • USB boundary: Host ports accept media and peripherals, while the device connection is reserved for the supported commissioning path

Three Network Roles Without One Shared Path

  • PROFIBUS: The RS 422/485 interface connects the panel to the supported DP network
  • Switched PROFINET: Two 10/100 Mbit/s RJ45 sockets share one logical interface through the integrated switch
  • Additional Ethernet: A separate Gigabit-capable RJ45 connection provides the documented basic Ethernet and PROFINET services

Cabinet Power and Short Interruption Behavior

  • Energy source: Communication cables do not power the panel; its electronics use the dedicated 24 V DC input
  • Tolerance window: The cabinet supply must remain inside 19.2–28.8 V DC at the panel terminals
  • Brief disturbance: The specified buffering interval defines how long V1 hardware can bridge a short input interruption
  • Sizing consequence: The panel load and any powered USB peripherals belong in the cabinet supply calculation
Description
Built around a 15.4-inch widescreen display and 36 physical function keys, Siemens 6AV2124-1QC02-0AX0 is the KP1500 Comfort operator panel in the SIMATIC HMI family. It presents the configured process view at 1280×800 pixels and returns operator commands through a key-operated front rather than a touchscreen.

Rather than sending every command through the ordinary HMI tag path, 6AV2124-1QC02-0AX0 can map selected keys directly into PROFIBUS DP or PROFINET IO data. Its RS 422/485 connection serves PROFIBUS, the paired 10/100 Mbit/s Ethernet ports form a switched PROFINET path, and the separate Gigabit-capable port provides another Ethernet interface for supported basic functions.

Screen projects, recipes, removable data, and service media occupy different storage areas in 6AV2124-1QC02-0AX0: 24 MB is assigned to application memory, 4 MB to recipe memory, an MMC/SD slot to runtime data, and a separate SD slot to the system card. The panel draws its operating power from a 24 V DC cabinet supply within 19.2–28.8 V DC; the V1 hardware is specified at 36 W with 20 ms of supply buffering.

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.
Which engineering version is needed to edit a Siemens 6AV2124-1QC02-0AX0 project?
Siemens 6AV2124-1QC02-0AX0 is configurable from WinCC Comfort V11 SP2; the existing project archive and installed panel image should be checked before any update.
How can I confirm that 6AV2124-1QC02-0AX0 is the key-operated KP1500 rather than a touch-panel variant?
The 6AV2124-1QC02-0AX0 front uses 36 function keys and labeling strips, while the KP1500 technical table lists no analog-resistive touchscreen.
Why does 6AV2124-1QC02-0AX0 have both data and system memory-card slots?
The 6AV2124-1QC02-0AX0 MMC/SD combination slot stores runtime data, while the separate SD system slot supports system and service functions; the cards should not be assigned interchangeably.
Which Ethernet port should be checked when a 6AV2124-1QC02-0AX0 loses controller communication?
For 6AV2124-1QC02-0AX0, first identify whether the project uses the switched 10/100 Mbit/s PROFINET pair or the independent Gigabit-capable basic interface, then check the matching IP configuration and cable.
What must the cabinet power supply provide for 6AV2124-1QC02-0AX0?
The 6AV2124-1QC02-0AX0 requires 24 V DC within 19.2–28.8 V DC, and the V1 device load should be planned from the documented 36 W consumption.
Can 6AV2124-1QC02-0AX0 direct keys be mapped through either PROFIBUS or PROFINET?
Yes. The 6AV2124-1QC02-0AX0 operating instructions provide direct-key assignments for both PROFIBUS DP and PROFINET IO, so the project and controller I/O map must use the selected bus.
