€ 1.995,00
The Siemens 6AV6341-1FC24-0AY0 is an OP27 operator panel belonging to the SIMATIC HMI family of operator panels. This unit is a compact, monochrome graphical operator panel designed for machine-level human-machine interface applications. It provides a robust and reliable interface for process visualization, parameter setting, and operator control in industrial environments.
The OP27 features a 5.7-inch STN monochrome LCD display with a resolution of 320 x 240 pixels (QVGA), capable of displaying text and graphics. The panel is equipped with a membrane keypad with function keys, system keys, and numeric/alphanumeric input keys for direct operator interaction without a touchscreen. It communicates via MPI (Multi-Point Interface) and PROFIBUS-DP interfaces, enabling direct connection to Siemens S7-300 and S7-400 PLCs. The unit operates on a 24 V DC supply and is rated IP65 at the front panel for protection against dust and water ingress.
The OP27 is widely used in machine building, manufacturing automation, and process industries where a cost-effective, durable operator interface is required at the machine level. It is particularly suited for applications involving Siemens SIMATIC S7 PLC systems, such as packaging machinery, conveyor systems, and general-purpose industrial machines. Its compact form factor and keypad-based operation make it appropriate for environments where touchscreen panels are not practical.

Common Error Codes & System Events
- Event ID: 10000
- Connection to PLC lost or communication timeout on MPI/PROFIBUS interface.
Check MPI/PROFIBUS cable connections and termination resistors. Verify PLC is powered and in RUN mode. Check bus address configuration on both OP27 and PLC. - Event ID: 10001
- No connection to configured PLC at startup.
Verify the PLC address and communication parameters in the project configuration match the physical setup. Check cable integrity and bus termination. - Event ID: 20000
- Configuration/project data error or missing project on the panel.
Re-download the project from SIMATIC ProTool or WinCC flexible to the OP27. Verify project compatibility with the panel firmware version. - Event ID: 40000
- Operating system or firmware error detected.
Perform a panel reset. If the error persists, update or reinstall the panel firmware using the appropriate Siemens service tool. - Event ID: 50000
- Internal hardware fault detected.
Power cycle the panel. If the fault recurs, the panel may require hardware inspection or replacement of the internal CPU board. - Event ID: 60000
- Recipe data or data record transfer error.
Check the data record configuration in the project. Verify sufficient memory is available on the panel and retry the transfer operation. - Event ID: 70000
- Alarm buffer overflow — too many pending alarms.
Acknowledge and clear pending alarms. Review alarm configuration to reduce simultaneous alarm occurrences or increase alarm buffer size in the project settings.
Frequently Asked Questions
Which PLCs are compatible with the OP27 (6AV6341-1FC24-0AY0)?
The OP27 is primarily designed for use with Siemens SIMATIC S7-300 and S7-400 PLCs via MPI or PROFIBUS-DP. It can also communicate with S5 PLCs using appropriate protocol settings.
What software is used to configure and program the OP27?
The OP27 is configured using Siemens SIMATIC ProTool or WinCC flexible (older versions). Projects are downloaded to the panel via MPI interface or a PC adapter cable.
What is the supply voltage for the 6AV6341-1FC24-0AY0?
The panel operates on a 24 V DC supply voltage.
Does the OP27 have a touchscreen?
No, the OP27 uses a membrane keypad with function keys, system keys, and alphanumeric keys for operator input. It does not have a touchscreen.
What is the front panel protection rating of the OP27?
The OP27 has an IP65 protection rating at the front panel, making it resistant to dust and water jets.
Troubleshooting
Display remains blank after power on
Check the 24 V DC supply voltage at the power connector. Verify the supply is within tolerance and the connector is properly seated.
Restore correct 24 V DC supply. If voltage is correct and display remains blank, inspect the internal backlight or power supply board. The backlight lamp or inverter board may require replacement.
Panel fails to communicate with PLC
Verify MPI or PROFIBUS-DP cable connections and bus termination at both ends. Check that the bus address configured in the OP27 project matches the physical PLC address.
Correct any address mismatches in the project configuration. Replace damaged cables or connectors. Ensure bus termination resistors are correctly installed at both ends of the bus segment.
Project download fails from engineering PC to OP27
Check the PC adapter cable connection to the MPI port. Verify the correct COM port and transfer speed are selected in ProTool or WinCC flexible. Confirm the panel is in transfer mode.
Switch the OP27 to transfer mode via the panel menu. Use a known-good PC adapter cable. Reduce the transfer baud rate if communication errors persist.
Operator keys are unresponsive or intermittently responsive
Inspect the membrane keypad for physical damage, contamination, or wear. Check the internal ribbon cable connection between the keypad and the main board.
Clean the keypad surface. If the ribbon cable is loose or damaged, reseat or replace it. If the keypad membrane is worn, replace the front panel assembly.
Panel displays 'System Fault' or restarts repeatedly
Check for unstable 24 V DC supply voltage or excessive electrical noise on the supply line. Inspect for overheating due to blocked ventilation or high ambient temperature.
Stabilize the power supply and add filtering if necessary. Ensure the ambient temperature is within the 0 to 50 °C operating range. If the fault persists after these checks, the internal CPU module may require replacement.
