€ 413,00
The Siemens 6AV6651-7DA02-3AA4 is a SIMATIC Mobile Panel 277 belonging to Siemens' SIMATIC HMI product family. It is a portable, handheld operator panel designed for mobile use in industrial environments, enabling operators to monitor and control machinery while moving freely around the plant floor. The device connects to the control system via a PROFINET interface and is suited for applications requiring flexible, untethered human-machine interaction.
The Mobile Panel 277 features a 7.5-inch TFT color display with a resolution of 640 x 480 pixels (VGA) and supports touch operation combined with function keys for versatile input. It is equipped with an integrated PROFINET/Industrial Ethernet interface for communication with SIMATIC S7 PLCs and other compatible controllers. The panel runs on the Windows CE operating system and supports WinCC flexible as its configuration software. A key safety feature is the integrated enabling device (three-position enabling switch) and an emergency stop button, making it suitable for safety-relevant applications in accordance with applicable machinery safety standards.
The SIMATIC Mobile Panel 277 is widely used in manufacturing, automotive, machine building, and process industries where operators need to perform setup, commissioning, or maintenance tasks directly at the machine. Its robust housing and IP65 protection rating make it suitable for harsh industrial environments with exposure to dust and water spray. The combination of mobility, safety features, and reliable PROFINET connectivity makes it a practical choice for applications such as robot cell operation, large machine tool setup, and assembly line maintenance.

Common Error Codes & System Events
- Event ID: 1000
- Communication error between the Mobile Panel and the connected PLC or controller. The PROFINET connection has been interrupted or cannot be established.
Check the PROFINET cable and connectors. Verify the IP address configuration of the panel and the PLC. Ensure the network switch or coupling station is powered and operational. - Event ID: 1003
- Project download failed or project data on the panel is corrupted or incompatible with the current WinCC flexible runtime version.
Re-download the project from the engineering station using WinCC flexible. Verify that the project version matches the runtime version installed on the panel. - Event ID: 2010
- Enabling switch not actuated or released. The three-position enabling switch is in the released (not pressed) or fully pressed (panic) position, disabling motion commands.
Ensure the enabling switch is held in the middle (enabled) position for motion-enabling functions. Check the enabling switch for mechanical damage or wear. - Event ID: 3010
- Emergency stop activated. The integrated emergency stop button on the Mobile Panel has been pressed.
Identify and resolve the cause of the emergency stop activation. Unlock the emergency stop button by rotating it, then acknowledge the fault in the control system before resuming operation. - Event ID: 4000
- Internal device temperature is outside the permissible operating range, indicating overheating or operation in an environment below the minimum temperature.
Check the ambient temperature at the operating location. Ensure the panel is used within the specified 0 °C to +50 °C operating temperature range. Allow the device to cool or warm to within range before restarting. - Event ID: 5000
- Power supply voltage is outside the permissible range. The 24 V DC supply to the panel is too low or too high.
Measure the supply voltage at the panel connector. Ensure the power supply provides a stable 24 V DC within the specified tolerance. Check cables and connectors for damage or loose connections. - Event ID: 6000
- Coupling station or connecting box fault detected. The panel cannot establish a valid connection to the docking station or PROFINET coupling unit.
Inspect the coupling station for faults or error indicators. Check the connecting cable between the panel and the coupling station. Replace the cable or coupling station if damaged.
Frequently Asked Questions
Which PLC systems are compatible with the SIMATIC Mobile Panel 277 (6AV6651-7DA02-3AA4)?
The Mobile Panel 277 is primarily designed for use with Siemens SIMATIC S7-300 and S7-400 PLCs via PROFINET/Industrial Ethernet. It can also communicate with S7-1200 and S7-1500 controllers when configured appropriately in WinCC flexible.
What configuration software is required to program the Mobile Panel 277?
The panel is configured using Siemens WinCC flexible 2008 or a compatible version. Projects are created on an engineering PC and downloaded to the panel via Ethernet or USB.
Does the Mobile Panel 277 support safety functions?
Yes, the 6AV6651-7DA02-3AA4 includes an integrated three-position enabling switch and an emergency stop button, supporting safety-relevant applications in accordance with machinery safety requirements up to a defined safety integrity level when integrated with a compatible safety controller.
What is the IP protection rating of the Mobile Panel 277?
The front of the panel is rated IP65, providing full protection against dust and water jets. The rear of the panel is rated IP54.
Can the Mobile Panel 277 be used wirelessly?
The 6AV6651-7DA02-3AA4 variant connects via a cable to a PROFINET coupling station rather than wirelessly. Siemens offers separate WLAN-capable variants of the Mobile Panel 277 family for wireless operation.
Troubleshooting
Display remains blank after power on
Check the 24 V DC supply voltage at the panel connector using a multimeter. Verify that the power cable and connector are undamaged and fully seated. Inspect the internal fuse if accessible.
Restore the 24 V DC supply within the specified tolerance. Replace any damaged power cables or connectors. If the supply is confirmed correct and the display remains blank, the internal power supply or display backlight may require replacement.
PROFINET communication cannot be established with the PLC
Verify the IP address and subnet mask configured on the panel match the network settings of the PLC and coupling station. Check the PROFINET cable for continuity and inspect the RJ45 connectors for damage or corrosion.
Reconfigure the IP address on the panel via the Control Panel in Windows CE. Replace damaged cables or connectors. Ensure the coupling station is powered and that the PROFINET device name is correctly assigned in the PLC project.
Touchscreen does not respond or responds inaccurately to touch input
Check whether the touchscreen surface is contaminated with liquids, debris, or gloves that are incompatible with resistive touch technology. Attempt to recalibrate the touchscreen via the Windows CE Control Panel.
Clean the touchscreen surface with a soft, dry cloth. Recalibrate the touch input through the system settings. If calibration does not resolve the issue, the touchscreen overlay may be damaged and require replacement.
Enabling switch does not enable motion functions
Test the three-position enabling switch by pressing it to the middle position and observing whether the control system acknowledges the enable signal. Check the wiring between the panel and the safety relay or controller input.
Inspect the enabling switch for mechanical wear or damage. Verify the safety circuit wiring according to the system documentation. If the switch is faulty, the Mobile Panel must be sent for repair or the enabling switch assembly replaced.
Project fails to load or runtime displays configuration errors after download
Compare the WinCC flexible project version with the runtime version installed on the panel. Check available storage memory on the panel. Review the download log in WinCC flexible for specific error messages.
Update the panel runtime to match the project version, or recompile the project in the correct WinCC flexible version. Clear old project data from the panel memory before re-downloading. Ensure the download connection is stable throughout the transfer.
