Description
Additional information

The Siemens 6AV6355-1GA00-0DM5 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 monochrome display with integrated function keys, enabling operators to monitor and control machine processes directly at the panel. As part of Siemens' established SIMATIC HMI line, it is engineered for reliable operation in demanding industrial conditions.

The OP 355 features a monochrome LCD display and a membrane keypad with dedicated function keys for direct process interaction without requiring a touchscreen. It communicates with SIMATIC PLCs via the MPI (Multi-Point Interface) or PROFIBUS DP protocol, allowing seamless integration into existing Siemens automation architectures. The panel supports configuration via Siemens ProTool or WinCC flexible engineering software, and includes onboard memory for storing project data, alarm messages, and recipes. The unit operates on a 24 V DC supply and is rated for panel mounting with a defined cutout dimension.

The OP 355 is commonly deployed in machine tool control, packaging machinery, conveyor systems, and general factory automation where a robust, key-operated interface is preferred over touchscreen operation. Its compatibility with SIMATIC S7-300 and S7-400 PLCs makes it a practical choice for retrofitting or extending existing Siemens-based control systems. The panel is suited for environments where operators require direct, tactile key input for reliable process control.

Common Error Codes & System Events

Event ID: 10000: Communication error between the HMI panel and the connected PLC. The connection to the configured PLC address cannot be established.
Check MPI or PROFIBUS DP cable connections and termination resistors. Verify the PLC address settings in the project configuration match the physical PLC address.
Event ID: 10001: Connection to PLC interrupted during runtime. The panel has lost communication with the PLC after a previously established connection.
Inspect cable integrity and connector seating. Check PLC operating state and ensure the PLC is in RUN mode. Restart the HMI panel if the connection is not automatically restored.
Event ID: 20000: Project download error. The transfer of the configuration project to the panel has failed or was interrupted.
Verify the PC-to-panel transfer cable is correctly connected. Ensure the panel is in Transfer mode before initiating download. Retry the download from ProTool or WinCC flexible.
Event ID: 40000: Internal memory error. The panel has detected a fault in its internal project or data memory.
Perform a memory reset via the panel's Start Center or Service menu. Re-download the project from the engineering software. If the error persists, the panel may require repair or replacement.
Event ID: 50000: Configuration error. The loaded project contains settings or objects that are incompatible with this panel type or firmware version.
Verify the project was compiled for the correct panel type (OP 355). Check firmware version compatibility and update if necessary. Recompile and re-download the project.
Event ID: 60000: Power supply undervoltage detected. The 24 V DC supply voltage has dropped below the minimum operating threshold.
Measure the supply voltage at the panel's power connector. Ensure the power supply unit is rated for sufficient current. Check wiring for voltage drops due to undersized cables or loose connections.

Frequently Asked Questions

What communication interfaces does the OP 355 (6AV6355-1GA00-0DM5) support?

The OP 355 supports MPI (Multi-Point Interface) and PROFIBUS DP for communication with SIMATIC PLCs. These interfaces allow direct integration with S7-300 and S7-400 controllers.

Which engineering software is used to configure the OP 355?

The OP 355 is configured using Siemens ProTool or WinCC flexible. Projects are compiled in the engineering software and then downloaded to the panel via a PC adapter cable.

What is the supply voltage for the 6AV6355-1GA00-0DM5?

The panel operates on a 24 V DC supply voltage, which is standard for SIMATIC HMI operator panels in this series.

Is the OP 355 compatible with SIMATIC S7-1200 or S7-1500 PLCs?

The OP 355 is primarily designed for use with SIMATIC S7-300 and S7-400 PLCs via MPI or PROFIBUS DP. Compatibility with S7-1200 or S7-1500 is not standard for this panel generation.

What is the front panel protection rating of the OP 355?

The front panel of the OP 355 is rated IP65, making it suitable for panel-mount installations where protection against dust and water jets is required.

Troubleshooting

Display remains blank after power on

Check that 24 V DC is present at the power supply terminals of the panel. Verify the power supply polarity is correct and the supply current capacity is sufficient.

Correct any wiring errors and ensure the power supply delivers stable 24 V DC. If voltage is confirmed correct and the display remains blank, the internal power supply board or display unit may require repair or replacement.

Panel fails to communicate with the PLC

Verify the MPI or PROFIBUS DP cable is correctly connected to both the panel and the PLC. Check that the bus address configured in the project matches the physical address set on the PLC and that termination resistors are correctly placed at both ends of the bus.

Replace or reseat the communication cable. Correct address mismatches in the project configuration and re-download. Ensure only the two physical ends of the bus segment have termination resistors enabled.

Project download from PC fails or times out

Confirm the panel is set to Transfer mode via the Start Center menu. Check that the correct COM port or USB adapter is selected in the engineering software transfer settings.

Switch the panel to Transfer mode before initiating the download. Use a compatible PC adapter (e.g., PC Adapter USB) and ensure the correct interface and baud rate are selected in ProTool or WinCC flexible.

Alarm messages are not displayed during runtime

Check the alarm configuration in the project to ensure alarm events are correctly linked to PLC data bits or tags. Verify the PLC program is writing to the correct memory addresses associated with the alarm triggers.

Review and correct the alarm tag assignments in the engineering project. Recompile and re-download the project to the panel. Confirm PLC logic is activating the correct alarm bits during the fault condition.

Panel repeatedly restarts or enters an error loop on startup

This may indicate corrupted project data in the panel memory or a firmware incompatibility. Access the Start Center by powering on the panel and observing if the Start Center menu is accessible.

Perform a factory reset or memory clear from the Start Center service menu. Re-download a freshly compiled project from the engineering software. If the issue persists, the panel hardware may require professional repair.
