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).

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
