Siemens 6AV6321-1BA24-0MY0 SIMATIC OP 24
€ 1.995,00
The Siemens 6AV6321-1BA24-0MY0 is an Operator Panel (OP) belonging to the SIMATIC HMI product family, designed for human-machine interface applications in industrial automation environments. This unit provides a compact, text-based operator interface for monitoring and controlling machine processes. It is part of Siemens' established SIMATIC OP series, which is widely deployed across manufacturing and process industries.
The OP 24 features a multi-line LCD text display capable of showing alphanumeric characters and process values, with dedicated function keys and membrane keypad for operator input. It supports serial communication interfaces for integration with SIMATIC S5 and S7 PLCs, as well as third-party controllers via standard protocols. The unit is built for industrial-grade reliability with a robust housing suitable for panel mounting, and operates from a 24 V DC supply.
This operator panel is typically used in machine-level control applications such as packaging machinery, conveyor systems, printing machines, and general-purpose industrial equipment. Its text-based interface makes it well-suited for parameter entry, status monitoring, and alarm display tasks where a full graphical HMI is not required. The compact form factor and straightforward configuration via SIMATIC ProTool software make it a practical choice for retrofit and new installation projects.

Common Error Codes & System Events
- Event ID: 10000
- Communication error between the OP and the connected PLC or controller. The connection has been interrupted or cannot be established.
Check the serial communication cable and connector integrity. Verify baud rate, parity, and address settings match the PLC configuration. Restart both devices if necessary. - Event ID: 10001
- Timeout error on the communication link. The OP did not receive a response from the PLC within the expected time window.
Check cable connections and communication parameters. Ensure the PLC program is running and the communication driver is active. - Event ID: 20000
- Configuration or project data error. The loaded project is incompatible or corrupted.
Reload the project using SIMATIC ProTool. Ensure the project version is compatible with the OP firmware version. - Event ID: 40000
- System memory error. Internal memory used for runtime data is insufficient or faulty.
Reduce the number of active tags or alarms in the project. If the error persists, perform a factory reset and reload the project. - Event ID: 50000
- Alarm buffer overflow. The number of pending alarms exceeds the buffer capacity of the operator panel.
Acknowledge and clear existing alarms. Review the alarm configuration in ProTool to reduce simultaneous alarm occurrences. - Event ID: 60000
- Firmware or operating system error detected during self-test at startup.
Cycle power to the device. If the error persists, update or reinstall the firmware using the appropriate Siemens transfer tool.
Frequently Asked Questions
What PLC systems is the 6AV6321-1BA24-0MY0 compatible with?
This operator panel is compatible with Siemens SIMATIC S5 and S7 PLC families via serial communication. It can also communicate with third-party controllers that support standard serial protocols such as RS-232 or RS-485.
What software is used to configure this operator panel?
The 6AV6321-1BA24-0MY0 is configured using Siemens SIMATIC ProTool software. Projects are created on a PC and transferred to the OP via a serial programming cable.
What is the supply voltage for this operator panel?
The unit operates from a 24 V DC power supply, which is standard for SIMATIC HMI panel installations.
What is the IP protection rating of this panel?
The front face of the operator panel is rated IP65, making it suitable for panel-mount installations where dust and water spray protection is required.
Can this operator panel display graphical content?
No, the OP 24 is a text-based operator panel and does not support graphical displays. It is designed for alphanumeric character display, process value monitoring, and alarm text output.
Troubleshooting
Display remains blank after power on
Check the 24 V DC supply voltage at the power connector. Verify the supply is within the specified voltage range and that the connector is fully seated.
Restore correct supply voltage. If voltage is present and display remains blank, inspect the internal fuse and replace if blown. If the fault persists, the display or internal power board may require replacement.
Communication fault displayed on screen, no connection to PLC
Verify the serial cable wiring between the OP and the PLC. Check that communication parameters (baud rate, parity, stop bits, station address) are correctly configured on both the OP and the PLC.
Correct any wiring faults or parameter mismatches. Replace the serial cable if continuity testing reveals a break. Reload the ProTool project if configuration data is suspected to be corrupted.
Operator keys not responding or responding incorrectly
Inspect the membrane keypad for physical damage, contamination, or deformation. Test individual keys in the OP diagnostic mode if available.
Clean the keypad surface with a dry cloth. If keys are mechanically damaged or the membrane is torn, the keypad assembly will need to be replaced.
Project transfer fails from PC to operator panel
Check the serial transfer cable connection between the PC and the OP. Verify the COM port settings in ProTool match the PC hardware. Ensure the OP is set to transfer mode.
Use a known-good Siemens-compatible transfer cable. Set the correct COM port and baud rate in ProTool. Place the OP in transfer mode by navigating to the transfer function in the OP menu before initiating the download.
Alarm messages appear in incorrect language or with garbled text
Check the language settings in the ProTool project and verify that the correct character set is selected for the target language. Confirm the project was fully transferred without errors.
Correct the language and character set configuration in ProTool and re-transfer the project to the OP. Ensure the firmware version supports the required character set.
