Siemens 6AV2123-2GB03-0AX0 SIMATIC KTP700 Basic HMI Panel
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Siemens 6AV2123-2GB03-0AX0 is a SIMATIC KTP700 Basic HMI panel designed for operator control and process monitoring in industrial automation applications. Equipped with a 7-inch widescreen TFT display supporting 65,536 colors and dimmable LED backlighting, the unit provides crisp 800 x 480 pixel resolution for process graphics and alarm displays. Operator input is performed through a combined touch screen interface and eight tactile, programmable function keys labeled F1 through F8. The panel operates on a 24 V DC power supply within a range of 19.2 to 28.8 V DC, featuring an IP65 rated front enclosure designed for dusty or wet environments.
Network integration with automation controllers is established through an integrated 10/100 Mbit/s PROFINET interface using an RJ45 connection, supporting communications with SIMATIC S7-1200, S7-1500, S7-300, and S7-400 PLCs. Putting a spare panel into operation requires loading the project application using WinCC Basic or STEP 7 Basic V13 SP1 or higher in TIA Portal. Alternatively, project backups and restores can be executed directly using a standard USB flash drive via the integrated USB 2.0 host port, allowing rapid software transfer on the factory floor without an engineering PC. ABC Industrial Parts can assist maintenance teams with sourcing fully tested replacement units and managing project configurations.
Diagnostic information is provided on-screen through real-time system alarm views and PLC connection status messages, supplemented by network diagnostics over PROFINET and TIA Portal. The physical function keys F1 through F8 incorporate integrated programmable LEDs that provide immediate status indication for dedicated key actions. Standard maintenance checks should verify the 24 V DC supply voltage, RJ45 fieldbus cable connections, and PLC communication status. If the unit suffers internal hardware faults or display failure, ABC Industrial Parts provides repair options and tested spare units to restore production with minimal delay.

Programming and Configuration
Engineering and software configuration for the Siemens 6AV2123-2GB03-0AX0 KTP700 Basic panel are conducted using Siemens TIA Portal software. Compatible packages include WinCC Basic or STEP 7 Basic, version V13 SP1 or higher. The panel features 10 MB of non-volatile onboard user memory, providing storage for visualization screens, alarm handling routines, process trend data, and recipes.
When commissioning a replacement device, the runtime application can be downloaded directly over the PROFINET network from TIA Portal. Alternatively, full project backups can be loaded into memory using a standard USB flash drive inserted into the panel's USB 2.0 host port, enabling direct software restore without needing an engineering software installation on-site.
Communication and System Integration
Industrial network communication is maintained via a built-in 10/100 Mbit/s PROFINET interface equipped with an RJ45 connector. This port enables integration into Ethernet automation networks and allows communication with connected controllers, including SIMATIC S7-1200, S7-1500, S7-300, and S7-400 PLCs.
In addition to network control, the panel includes a single USB 2.0 Type-A host port. This USB port supports data logging, project backups, software updating, and connection of compatible USB peripherals directly at the machine panel.
Diagnostics and Status Indication
System state monitoring and fault analysis are managed through on-screen system alarm views, PLC status messages, PROFINET network diagnostics, and TIA Portal system diagnostic tools. These features allow operators and technicians to identify controller communication drops or system faults directly from the display.
The eight tactile function keys (F1-F8) include programmable integrated status LEDs. These indicators can be configured within the TIA Portal project to signal machine states, function acknowledgments, or active warning conditions.
Status LED Indicators
| LED | Color/Status | Meaning |

| Function Key LEDs | Programmable | Programmable status indicators integrated into physical function keys F1-F8 |
Replacement and Spare Part Considerations
Replacing an existing panel requires a cabinet cutout measuring 197 mm in width by 141 mm in height to accommodate the panel's overall dimensions of 214 x 158 x 39 mm. Proper seating with the integrated seal maintains IP65 protection for the front panel, protecting internal components against moisture and dust ingress.
The electrical power source must supply a regulated 24 V DC (acceptable range 19.2 to 28.8 V DC). To ensure seamless system startup, verify that the replacement panel receives the correct TIA Portal project software and network address settings via PROFINET or USB restore prior to placing the equipment back into automated operation.
Frequently Asked Questions
Which software version is required to program the 6AV2123-2GB03-0AX0 panel?
The Siemens 6AV2123-2GB03-0AX0 requires WinCC Basic or STEP 7 Basic V13 SP1 or higher within TIA Portal for project engineering and programming.
Can I replace a damaged panel without using TIA Portal software?
Yes, if a project backup was saved to a standard USB flash drive, the runtime project can be restored directly to the spare panel via its onboard USB 2.0 host port.
Which PLC models are compatible with the KTP700 Basic over PROFINET?
The panel communicates directly over PROFINET with SIMATIC S7-1200, S7-1500, S7-300, and S7-400 controllers.
What cutout dimensions are required to mount this panel?
The required control panel cutout dimensions are 197 mm wide by 141 mm high.
What is the function of the LEDs on the tactile keys?
The eight physical function keys (F1-F8) feature integrated programmable LEDs that serve as status indicators configurable within the TIA Portal application.
