Description
Additional information

The Siemens 6AG1123-2GA03-2AX0 is a member of the SIPLUS HMI Comfort series, designed as a ruggedized variant of the standard SIMATIC HMI TP 1200 Comfort panel. It belongs to the SIPLUS extreme product line, which is engineered for operation in harsh and demanding environmental conditions beyond the scope of standard industrial panels. This 12-inch touch panel provides a high-performance human-machine interface solution for process visualization and machine control applications.

The TP 1200 Comfort panel features a 12.1-inch widescreen TFT display with a resolution of 1280 x 800 pixels and 16 million colors, delivering clear and detailed process visualization. It supports both PROFINET and MPI/PROFIBUS communication interfaces, enabling integration into a wide range of Siemens automation architectures. The panel is equipped with 12 MB user memory for project data, supports USB host and device interfaces, and runs the WinCC flexible runtime environment. The SIPLUS variant includes conformal coating on the PCBs and extended temperature tolerance, making it suitable for environments with condensation, corrosive atmospheres, and increased vibration levels.

The 6AG1123-2GA03-2AX0 is used in industries such as chemical processing, oil and gas, water and wastewater treatment, food and beverage, and marine applications where standard HMI panels would be exposed to corrosive gases, humidity, or temperature extremes. Its robust construction makes it particularly suitable for outdoor enclosures, offshore platforms, and production environments with aggressive ambient conditions. The panel integrates seamlessly with Siemens S7-300, S7-400, S7-1200, and S7-1500 PLC families.

Common Error Codes & System Events

Event ID: 10000: Connection to the PLC could not be established or was interrupted during runtime.
Check PROFINET or PROFIBUS cabling and connector integrity. Verify PLC IP address or MPI/DP address settings in the HMI project configuration. Ensure the PLC is in RUN mode.
Event ID: 20000: Project download failed or project data is corrupted on the panel.
Re-download the project from TIA Portal or WinCC flexible. Ensure the project is compiled without errors before transfer. Check USB or Ethernet connection used for download.
Event ID: 40000: System memory or user memory is critically low.
Delete unused project data, archived logs, or recipe files from the panel. Consider increasing memory allocation in the project settings or using an external memory card.
Event ID: 50000: Internal hardware fault detected, such as a failure in the touch screen controller or display backlight.
Perform a panel restart. If the fault persists, check for physical damage to the display assembly. The unit may require repair or replacement of the display module.
Event ID: 60000: Operating system error or firmware fault detected on the panel.
Perform a factory reset via the Start Center (loader menu). Re-flash the panel firmware using the ProSave tool or TIA Portal. Backup project data before performing a reset.
Event ID: 70000: Configuration error detected; a tag or screen object references an invalid or missing PLC variable.
Review the project in TIA Portal or WinCC flexible for unresolved tag connections. Recompile and re-download the project after correcting all configuration errors.
Event ID: 80000: Date and time synchronization error; the panel clock has lost its settings, typically due to a discharged backup battery.
Replace the internal backup battery (CR2032 or equivalent as specified in the device manual). Reconfigure the date and time settings or enable NTP synchronization via PROFINET.

Frequently Asked Questions

What is the supply voltage for the 6AG1123-2GA03-2AX0?

The panel operates on 24 V DC. Ensure the power supply is within the specified tolerance range as defined in the SIPLUS HMI Comfort operating instructions.

What makes the SIPLUS variant different from the standard SIMATIC HMI TP 1200 Comfort?

The SIPLUS variant (6AG1123-2GA03-2AX0) features conformal coating on the printed circuit boards and is rated for extended temperature ranges and environments with condensation or corrosive atmospheres. It is functionally equivalent to the standard TP 1200 Comfort but designed for harsher operating conditions.

Which PLC families are compatible with this HMI panel?

The panel is compatible with Siemens S7-300, S7-400, S7-1200, and S7-1500 PLC families via PROFINET or MPI/PROFIBUS DP interfaces. Third-party PLCs can also be connected using available communication drivers in TIA Portal or WinCC flexible.

What software is used to program and configure this panel?

The 6AG1123-2GA03-2AX0 can be configured using Siemens TIA Portal with the WinCC Comfort/Advanced option. It is also compatible with the legacy WinCC flexible engineering software.

Does this panel support recipe and data logging functions?

Yes, the TP 1200 Comfort supports recipe management, data logging, alarm logging, and trend display functions. Data can be stored internally or on an external USB storage device or SD card.

Troubleshooting

Display remains blank after power is applied

Measure 24 V DC at the power supply connector on the rear of the panel. Check that the voltage is within the acceptable range. Inspect the internal fuse if accessible. Attempt to determine if the backlight has failed by shining a light at the display surface to check for a faint image.

If voltage is correct but display is blank, the backlight inverter or display module may have failed. Replace the backlight or display assembly. If no voltage is present, check the external power supply and wiring. Reset the panel by briefly removing power.

Touch screen does not respond or responds inaccurately

Check whether the touch screen is physically damaged or contaminated with liquids or debris. In the Start Center (loader menu), navigate to the touch calibration utility to determine if calibration has drifted.

Clean the touch surface with a soft, dry cloth. Perform a touch screen recalibration via the Start Center. If the touch screen remains unresponsive after calibration, the resistive touch overlay may be damaged and requires replacement.

Panel fails to establish communication with the PLC

Verify the PROFINET IP address or PROFIBUS DP address configured on the HMI matches the settings in the project. Use a network diagnostic tool or the TIA Portal device scan to confirm the PLC is reachable on the network. Check cable integrity and switch/hub status.

Correct any IP address or bus address mismatches in the HMI project and re-download. Replace damaged Ethernet or PROFIBUS cables. Ensure the PLC is powered and in RUN mode. Check firewall or managed switch settings that may be blocking communication.

Panel continuously reboots or freezes during operation

Check for unstable 24 V DC supply voltage, particularly voltage dips during machine operation. Review the system event log in the panel for recurring fault event IDs. Determine if the issue is project-related by loading a minimal test project.

Stabilize the power supply and ensure adequate current capacity. If the issue is project-related, optimize the project by reducing scan cycles or simplifying complex scripts. If hardware instability is confirmed, the panel may require servicing or replacement of the main CPU board.

Project download fails or panel is not detected by TIA Portal

Verify the Ethernet or USB connection between the engineering PC and the panel. Confirm the panel is in transfer mode (accessible via the Start Center). Check that the PC firewall is not blocking the Siemens communication ports.

Switch the panel to transfer mode manually via the Start Center loader. Disable PC firewall temporarily during download or add exceptions for TIA Portal. Try an alternative USB or Ethernet cable. Ensure the TIA Portal version is compatible with the panel firmware version; update firmware via ProSave if necessary.
