€ 1.995,00
The Siemens 6AV6321-1BA13-1MY0 is an operator panel (OP) belonging to the SIMATIC HMI product family, designed for human-machine interface applications in industrial automation environments. This unit functions as a text-based operator panel, providing a compact and robust interface for machine monitoring and control. It is part of Siemens' established SIMATIC HMI line, which is widely deployed across process and discrete manufacturing sectors.
The 6AV6321-1BA13-1MY0 features a multi-line text display capable of presenting process values, alarms, and operator prompts in a clear format. It supports serial communication interfaces for integration with SIMATIC S7 PLCs and other compatible controllers, and includes configurable function keys for direct operator input. The panel is designed for panel-mount installation with a defined cutout dimension, and is built to withstand typical industrial environmental conditions including vibration and temperature variation.
This operator panel is suited for use in machine building, conveyor systems, packaging machinery, and general factory automation where a cost-effective, text-based HMI solution is required. Its compact form factor makes it appropriate for integration into control cabinets and machine panels with limited space. The unit is particularly common in retrofit and upgrade projects where a reliable, straightforward operator interface is needed without the overhead of a full graphical HMI system.

Common Error Codes & System Events
- Event ID: 10000
- Communication error between the operator panel and the connected PLC or controller.
Check the communication cable connections and verify the MPI/PROFIBUS address settings on both the panel and the PLC. Ensure baud rate settings match. - Event ID: 10001
- Connection to the configured PLC has been lost or interrupted.
Verify the physical connection and cable integrity. Check PLC power status and confirm the PLC is in RUN mode. - Event ID: 20000
- Configuration or project data on the panel is missing or corrupted.
Re-download the project configuration to the panel using SIMATIC WinCC flexible or ProTool. Ensure the correct project version is used. - Event ID: 40000
- Internal device error detected during self-test at startup.
Perform a power cycle. If the error persists, check for hardware faults and consider replacing the unit or contacting Siemens technical support. - Event ID: 50000
- Alarm buffer overflow — too many pending alarms have exceeded the buffer capacity.
Acknowledge and clear existing alarms. Review the alarm configuration in the project to reduce simultaneous alarm occurrences. - Event ID: 60000
- Operator panel has been switched to transfer mode awaiting a new project download.
Initiate a project download from the engineering station using SIMATIC WinCC flexible or ProTool to complete the transfer. - Event ID: 70000
- Incorrect or incompatible project file detected on the panel.
Verify that the project was compiled for the correct panel type and firmware version, then re-download the correct project file.
Frequently Asked Questions
Which engineering software is used to configure the 6AV6321-1BA13-1MY0?
This panel is configured using Siemens SIMATIC ProTool or WinCC flexible, depending on the firmware version and project requirements.
Which PLCs is this operator panel compatible with?
The panel is compatible with Siemens SIMATIC S7-200, S7-300, and S7-400 PLCs via MPI or PROFIBUS DP communication interfaces.
What is the supply voltage for this operator panel?
The 6AV6321-1BA13-1MY0 operates on a 24 V DC supply voltage.
What is the IP protection rating of the front panel?
The front panel carries an IP65 protection rating, making it suitable for environments where dust and water spray may be present.
Can this panel be used as a replacement for older SIMATIC OP panels?
Yes, the 6AV6321-1BA13-1MY0 is designed to be compatible with existing SIMATIC HMI project configurations, making it suitable for replacement and retrofit applications in systems previously using comparable OP-series panels.
Troubleshooting
Display remains blank after power on
Measure the 24 V DC supply voltage at the panel's power connector. Check for blown fuses or wiring faults in the supply circuit.
Restore the correct 24 V DC supply. If voltage is present and the display remains blank, the internal power supply or display unit may be faulty and the panel should be repaired or replaced.
Panel shows communication error at startup
Check the MPI or PROFIBUS DP cable connections between the panel and the PLC. Verify that the bus address and baud rate configured on the panel match the PLC settings.
Correct any wiring faults, ensure proper bus termination resistors are in place, and align the communication parameters on both the panel and the PLC.
Project cannot be downloaded to the panel
Confirm the panel is in transfer mode and that the correct communication interface and port settings are configured in the engineering software.
Switch the panel to transfer mode manually if required, verify the PC-to-panel cable or network connection, and ensure the project is compiled for the correct panel type before re-attempting the download.
Function keys do not respond to operator input
Check whether the panel is in the correct operating mode and that the project configuration has assigned actions to the function keys. Inspect for physical damage to the keypad.
Re-download the project with correct function key assignments. If the keypad is physically damaged, the panel will require hardware repair or replacement.
Alarms are not displayed on the panel
Verify that the alarm configuration in the project is correctly linked to the PLC data addresses. Check that the PLC is writing the expected values to the alarm trigger bits.
Correct the alarm tag addresses in the project configuration and re-download. Confirm PLC logic is correctly setting alarm bits during fault conditions.
