€ 693,81
The Siemens 6AV6355-1GA00-0DM4 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, robust interface for process visualization and machine control, integrating directly with Siemens SIMATIC PLCs and other compatible controllers. The OP 355 series is part of Siemens' established line of text-based and graphical operator panels intended for straightforward process monitoring and parameter input.
The OP 355 features a monochrome LCD display suitable for text and basic graphical representation of process data, along with a membrane keypad for operator input. It supports serial communication interfaces, typically MPI (Multi-Point Interface) and/or PROFIBUS DP, enabling direct integration with SIMATIC S7-300 and S7-400 PLCs. The panel is configured using Siemens ProTool or WinCC flexible engineering software, allowing the creation of screens, alarms, and recipes. The unit operates on a 24 V DC supply and is designed for panel mounting with an IP65 front protection rating.
The OP 355 is commonly deployed in manufacturing, process automation, and machine building applications where a reliable, straightforward operator interface is required. It is well-suited for tasks such as displaying process values, entering setpoints, and acknowledging alarms on machinery such as conveyor systems, packaging machines, and production lines. Its compatibility with the SIMATIC S7 controller family makes it a practical choice for facilities already standardized on Siemens automation infrastructure.

Common Error Codes and System Events
- Event ID: 1000
- Controller not available – no communication established between the HMI panel and the configured PLC.
Check MPI/PROFIBUS cable connections and termination resistors. Verify PLC address settings match the HMI project configuration. Confirm PLC is powered and in RUN mode. - Event ID: 1003
- Connection to PLC interrupted during operation.
Inspect communication cable for damage. Check bus termination and cable shielding. Verify MPI/PROFIBUS network configuration and node addresses. - Event ID: 10000
- Project download error – project transfer to the panel failed or was interrupted.
Check the transfer cable connection between the PC and the panel. Ensure the panel is set to transfer mode. Retry the download using ProTool or WinCC flexible. - Event ID: 10001
- Insufficient memory – the project exceeds the available memory on the operator panel.
Reduce the project size by removing unused screens, graphics, or recipes. Check the memory requirements against the panel's available capacity. - Event ID: 20000
- System startup error – the panel failed to initialize correctly on power-up.
Cycle power to the panel. If the error persists, perform a factory reset and re-download the project. Check the 24 V DC supply voltage is within specification. - Event ID: 40000
- Tag read/write error – a configured tag could not be read from or written to the PLC.
Verify the tag address in the HMI project matches the actual PLC data block or memory address. Check PLC program for address conflicts. - Event ID: 50000
- Alarm buffer overflow – the number of pending alarms exceeds the panel's alarm buffer capacity.
Acknowledge and clear existing alarms. Review the alarm configuration to reduce simultaneous alarm generation. Increase alarm buffer size in the project if possible.
Frequently Asked Questions
Which PLCs are compatible with the Siemens 6AV6355-1GA00-0DM4?
The OP 355 is designed for use with Siemens SIMATIC S7-300 and S7-400 PLCs via MPI or PROFIBUS DP communication interfaces. It may also support S5 controllers depending on the configured driver.
What software is used to configure and program this operator panel?
The 6AV6355-1GA00-0DM4 is configured using Siemens ProTool or WinCC flexible engineering software. The project is then transferred to the panel via a serial PC/PPI cable or MPI adapter.
What is the supply voltage for the OP 355?
The panel operates on a 24 V DC supply voltage. Ensure the power source is stable and within the specified tolerance range to prevent operational issues.
What is the front panel protection rating of this HMI?
The OP 355 provides an IP65 protection rating on the front face when correctly installed in a panel cutout, making it suitable for environments with dust and water spray exposure.
Can the OP 355 be used as a replacement for older Siemens OP panels?
The OP 355 can serve as a replacement for earlier SIMATIC OP series panels in many applications, provided the project is reconfigured or migrated using the appropriate version of ProTool or WinCC flexible to match the new hardware.
Troubleshooting
Display remains blank after power on
Check the 24 V DC supply voltage at the panel's power connector using a multimeter. Inspect internal fuses if accessible. Verify the power supply unit is functioning correctly.
Ensure the supply voltage is within the 24 V DC specification. Replace any blown fuses. If the display backlight has failed, the backlight unit or the panel itself may require replacement.
No communication with PLC after startup
Verify the MPI or PROFIBUS DP cable is correctly connected and terminated at both ends. Check that the node address configured in the HMI project matches the physical PLC address. Use a PROFIBUS diagnostic tool to check bus integrity.
Correct any address mismatches in the HMI project configuration. Replace damaged cables or connectors. Ensure bus termination resistors are enabled only at the two physical ends of the network segment.
Project download fails from engineering PC
Confirm the panel is in transfer mode (accessible via the panel's start menu or boot loader). Check the PC-to-panel communication cable for continuity. Verify the correct COM port and transfer settings are selected in ProTool or WinCC flexible.
Switch the panel to transfer mode before initiating the download. Replace the transfer cable if faulty. Ensure the engineering software version is compatible with the panel firmware version.
Operator keypad inputs not responding
Inspect the membrane keypad for physical damage, contamination, or deformation. Check the internal ribbon cable connection between the keypad and the main board if the panel is open for service.
Clean the keypad surface if contamination is present. If the ribbon cable is loose or damaged, reseat or replace it. If the keypad membrane itself is faulty, replace the keypad assembly.
Alarm messages displayed in incorrect language or garbled text
Check the language settings within the HMI project configuration. Verify the correct character set and font are assigned to the alarm texts in ProTool or WinCC flexible.
Reconfigure the language and character set settings in the engineering software and re-download the project to the panel. Ensure the panel firmware supports the required language and character encoding.
