Description
Additional information

The Siemens 6AV6355-1AA31-8DM5 is an operator panel belonging to the SIMATIC OP 35 family, part of Siemens' established range of operator panels for industrial human-machine interface applications. This unit provides a monochrome graphical display with integrated function keys, enabling operators to monitor and control machine processes directly at the panel. The OP 35 series is designed for use with Siemens SIMATIC S5 and S7 programmable logic controllers, offering a compact and robust interface solution.

The OP 35 features a 5.7-inch STN monochrome LCD display with a resolution of 320 x 240 pixels, providing clear visualization of process data, alarms, and operator prompts. The panel includes a membrane keypad with dedicated function keys, numeric keys, and system keys for navigation and data entry without requiring a touchscreen. Communication is handled via MPI, PROFIBUS-DP, and serial interfaces (RS-232/RS-422/RS-485), allowing integration into a variety of SIMATIC network architectures. The unit operates on a 24 V DC supply and is rated to IP 65 at the front panel, providing protection against dust and water ingress in industrial environments.

The OP 35 is commonly deployed in manufacturing, machine building, and process automation applications where a reliable, key-operated HMI is preferred over touchscreen solutions. It is well suited for controlling conveyor systems, packaging machinery, press lines, and general-purpose machine tools. The panel's compatibility with both S5 and S7 controllers makes it a practical choice for facilities operating mixed or legacy Siemens PLC environments.

Common Error Codes & System Events

Event ID: 1000: Connection to PLC lost or communication timeout detected on the configured interface.
Check MPI or PROFIBUS-DP cable connections, verify PLC address settings, and confirm the PLC is powered and in RUN mode.
Event ID: 1003: Configuration data on the panel does not match the project downloaded or is corrupted.
Re-download the project from ProTool or STEP 7 to the OP 35 and perform a panel restart.
Event ID: 1004: No project found in the panel memory; the panel starts in transfer mode.
Download a valid project to the panel using ProTool via the configured serial or MPI interface.
Event ID: 2010: Alarm buffer overflow; the number of pending alarms exceeds the buffer capacity.
Acknowledge and clear existing alarms. Review alarm configuration in ProTool to reduce simultaneous alarm generation.
Event ID: 3010: Internal panel memory error detected during self-test at startup.
Perform a factory reset of the panel. If the error persists, the internal memory or hardware may require replacement.
Event ID: 4000: Transfer mode active; panel is waiting for a project download from the configuration PC.
Initiate project download from ProTool, or restart the panel with a valid project already stored in memory.
Event ID: 5010: Recipe data error; recipe records could not be read or written correctly.
Check recipe configuration in the project. Re-download the project and verify available panel memory for recipe storage.

Frequently Asked Questions

Which configuration software is used to program the OP 35?

The OP 35 is configured using Siemens ProTool software. Projects are downloaded to the panel via the serial interface or MPI connection.

Which Siemens PLCs are compatible with the OP 35?

The OP 35 is compatible with SIMATIC S5 and S7 series PLCs, communicating via MPI, PROFIBUS-DP, or serial interfaces depending on the PLC type.

What is the supply voltage for the 6AV6355-1AA31-8DM5?

The panel requires a 24 V DC supply, with an acceptable input range of 18 V DC to 30 V DC.

Does the OP 35 support touchscreen input?

No, the OP 35 uses a membrane keypad with function keys, numeric keys, and navigation keys. It does not have a touchscreen.

What is the front panel protection rating of the OP 35?

The front panel of the OP 35 is rated to IP 65, providing full protection against dust and resistance to water jets.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the panel power connector. Check that the voltage is within the 18–30 V DC range. Inspect the internal fuse if accessible.

Correct the supply voltage if out of range. Replace the internal fuse if blown. If the display remains blank with correct supply voltage, the backlight or internal power board may require replacement.

Panel repeatedly enters transfer mode on startup

This indicates no valid project is stored in panel memory, or the project has been corrupted. Check whether a project was previously downloaded successfully.

Connect a PC with ProTool installed and download a valid project to the panel via the serial or MPI interface. Ensure the download completes without errors before restarting.

Communication fault to PLC displayed on screen

Verify the MPI or PROFIBUS-DP cable is securely connected at both the panel and PLC ends. Check that the PLC station address configured in the project matches the actual PLC address.

Replace or reseat the communication cable. Correct the PLC address in the ProTool project and re-download. Verify the PLC is powered and in RUN mode.

Function keys do not respond or respond incorrectly

Inspect the membrane keypad for physical damage, contamination, or deformation. Test individual keys in the panel's built-in key test mode if available.

Clean the keypad surface. If keys are physically damaged or the membrane is worn, replace the keypad membrane assembly. If the issue persists, the keypad connector to the main board may need reseating.

Alarms are displayed but cannot be acknowledged

Check the alarm configuration in the ProTool project to confirm that acknowledgement is enabled for the relevant alarm class. Verify that the PLC bit associated with alarm acknowledgement is being correctly processed.

Correct the alarm class configuration in ProTool and re-download the project. Ensure the PLC program correctly handles the acknowledgement bit handshake with the OP 35.
