Description
Additional information

The Siemens 6AV6355-1AA31-8DM4 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 automation processes directly at the machine. The OP 35 series is designed for use with Siemens SIMATIC S5 and S7 programmable logic controllers, as well as third-party controllers via standard communication protocols.

The OP 35 features a built-in STN LCD display with a resolution of 320 x 240 pixels (QVGA), supporting the display of text, graphics, and process values. The panel is equipped with membrane keypad function keys and system keys for navigation and data entry. Communication is handled via the MPI (Multi-Point Interface) and PROFIBUS-DP interfaces, allowing direct integration into Siemens automation networks. The unit operates on a 24 V DC supply and is configured using Siemens ProTool software. It supports recipe management, alarm logging, and trend display functions.

The SIMATIC OP 35 is widely deployed in manufacturing, machine building, and process automation environments where a robust, panel-mounted operator interface is required. It is commonly found on packaging machinery, conveyor systems, and general-purpose industrial machines where operators need local access to process data and control functions. The panel-mount design and IP65 front protection rating make it suitable for installation in control cabinet doors in demanding industrial environments.

Common Error Codes & System Events

Event ID: 10000: Communication error between the OP panel and the connected PLC. The panel cannot establish or maintain a connection to the controller.
Check MPI or PROFIBUS-DP cable connections and termination resistors. Verify the PLC address settings match the configuration in ProTool. Ensure the PLC is powered and in RUN mode.
Event ID: 10001: Timeout error on the communication link. The panel did not receive a response from the PLC within the expected time window.
Check network cable integrity and connector seating. Verify bus termination at both ends of the PROFIBUS or MPI segment. Reduce bus length or check for electromagnetic interference sources.
Event ID: 20000: Configuration or project data error. The project loaded on the panel is incompatible or corrupted.
Re-download the project from ProTool to the OP panel. Verify that the ProTool project version is compatible with the OP 35 firmware version.
Event ID: 40000: Alarm buffer overflow. The number of pending alarms has exceeded the panel's alarm buffer capacity.
Acknowledge and clear existing alarms on the panel. Review the alarm configuration in ProTool to reduce unnecessary alarm triggers or increase acknowledgement frequency.
Event ID: 50000: Recipe data error. A recipe transfer between the panel and PLC has failed or the recipe data is inconsistent.
Check the recipe configuration in ProTool for data type mismatches. Re-transfer the recipe data and verify PLC data block addresses are correctly mapped.
Event ID: 60000: Internal panel hardware fault. A self-diagnostic check has detected an internal error.
Perform a panel restart by cycling the 24 V DC power supply. If the fault persists, the panel may require repair or replacement of internal components.

Frequently Asked Questions

What communication interfaces does the OP 35 (6AV6355-1AA31-8DM4) support?

The OP 35 supports MPI (Multi-Point Interface) and PROFIBUS-DP communication interfaces, allowing direct connection to Siemens S7 PLCs and other PROFIBUS-compatible controllers.

What software is used to configure and program the OP 35?

The OP 35 is configured using Siemens ProTool software. Projects are created on a PC and then downloaded to the panel via the MPI or PROFIBUS-DP interface.

What is the supply voltage for the 6AV6355-1AA31-8DM4?

The panel operates on a 24 V DC supply voltage, which is standard for SIMATIC operator panels and compatible with most industrial control cabinet power supplies.

Is the OP 35 compatible with Siemens S5 PLCs?

Yes, the OP 35 can be configured to communicate with both SIMATIC S5 and S7 PLCs, as well as third-party controllers that support the relevant communication protocols.

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

The OP 35 has an IP65 protection rating on the front panel, making it resistant to dust ingress and low-pressure water jets, suitable for installation in industrial control cabinet doors.

Troubleshooting

Display remains blank after power is applied

Measure the 24 V DC supply voltage at the panel's power connector. Check for blown internal fuses or a faulty power supply unit feeding the panel.

Ensure the 24 V DC supply is within tolerance and the connector is fully seated. If the supply is correct but the display remains blank, the internal power supply board or backlight may require replacement.

Panel fails to communicate with the PLC

Check the MPI or PROFIBUS-DP cable for continuity and correct pin assignment. Verify that bus termination resistors are active at both ends of the network segment and that the panel address matches the ProTool configuration.

Replace or reseat the communication cable. Correct the bus address settings in ProTool and re-download the project. Ensure only the two physical end nodes on the bus have termination active.

Touchscreen or keypad inputs are not responding

Check whether the panel is in a locked or password-protected state. Test each function key individually to determine if the fault is isolated to specific keys or the entire keypad.

Disable any active operator lockout via the panel menu. If individual keys are unresponsive, the membrane keypad assembly may be worn or damaged and should be replaced.

Project download from ProTool fails or is interrupted

Verify the PC-to-panel communication cable (PC adapter or MPI cable) is correctly connected and the COM port or USB adapter is recognised by the PC. Check that the ProTool project is compiled without errors.

Reinstall the PC adapter driver and select the correct interface in ProTool transfer settings. Recompile the project and retry the download. Ensure no other software is occupying the COM port during transfer.

Alarm messages are displayed in incorrect language or with garbled text

Check the language settings within the ProTool project and verify that the correct character set is assigned to the panel. Confirm the downloaded project version matches the intended language configuration.

Correct the language and character set settings in ProTool and re-download the project to the panel. Ensure the panel firmware supports the required language character set.
