Siemens 6AV3505-1FB12 SIMATIC OP5
€ 312,00
The Siemens 6AV3505-1FB12 is an Operator Panel (OP5) belonging to the SIMATIC HMI family, designed for human-machine interface applications in industrial automation environments. This compact operator panel provides a straightforward text-based interface for monitoring and controlling machine processes. It is part of Siemens' legacy SIMATIC OP series, which was widely deployed across a broad range of industrial control systems.
The OP5 features a single-line LCD text display capable of showing alphanumeric characters, enabling operators to read process values, status messages, and alarm texts directly at the machine. It communicates via a serial interface (TTY or RS-232) and is compatible with Siemens SIMATIC S5 and S7 PLC families through the appropriate protocol configuration. The panel is powered by 24 V DC and is built for panel-mount installation, with a robust front face rated for industrial environments. Configuration is performed using the ProTool software package.
The SIMATIC OP5 is typically used in manufacturing, packaging, and process automation applications where a compact, cost-effective operator interface is required for basic parameter display and entry. Its small form factor makes it suitable for integration into machine control cabinets and local operator stations where space is limited. It is particularly common in legacy system installations and retrofitting projects where compatibility with older SIMATIC S5 or early S7 controllers is required.

Common Error Codes & System Events
- System Error 1
- Communication error between the OP5 and the connected PLC. The panel cannot establish or maintain a connection via the configured serial interface.
Check serial cable wiring and connections. Verify baud rate, parity, and protocol settings match the PLC configuration. Ensure the PLC program contains the correct communication blocks. - System Error 2
- Configuration data in the operator panel is invalid or corrupted. The panel cannot load the project data correctly.
Re-download the project configuration from ProTool to the OP5. If the error persists, check the integrity of the project file and repeat the transfer. - System Error 3
- Checksum error detected in the panel's internal memory. Stored configuration or project data may be corrupted.
Perform a complete re-download of the project using ProTool. If the error recurs, the internal memory module may need replacement. - No Project
- The operator panel has powered on but no valid project configuration is found in memory.
Connect the OP5 to a PC running ProTool and download a valid project configuration to the device. - PLC Not Responding
- The OP5 has lost communication with the PLC during operation. The PLC is not responding to polling requests from the panel.
Verify PLC is powered and running. Check all serial cable connections and interface adapters. Confirm communication parameters (baud rate, address) are correctly set on both devices. - Overflow
- A numeric value entered by the operator exceeds the defined limit for the associated variable or data field.
Re-enter a value within the configured minimum and maximum limits for the variable. Review the project configuration in ProTool to adjust limits if necessary. - Transfer Mode Active
- The panel is in data transfer mode, awaiting a project download from the ProTool configuration software.
Initiate the project transfer from the ProTool software on the connected PC, or restart the panel to exit transfer mode if a download is not intended.
Frequently Asked Questions
Which PLCs are compatible with the SIMATIC OP5 (6AV3505-1FB12)?
The OP5 is compatible with Siemens SIMATIC S5 and SIMATIC S7 PLC families via serial communication using TTY (20 mA current loop) or RS-232 interfaces with the appropriate protocol settings.
What software is used to configure the 6AV3505-1FB12?
The OP5 is configured using Siemens ProTool configuration software. The project is created on a PC and then downloaded to the panel via the serial interface.
What is the supply voltage for the OP5 operator panel?
The 6AV3505-1FB12 operates on a 24 V DC supply voltage.
What is the front panel protection rating of the OP5?
The front face of the OP5 operator panel is rated IP65, providing protection against dust ingress and low-pressure water jets, making it suitable for industrial panel-mount installations.
Can the 6AV3505-1FB12 display alarm messages?
Yes, the OP5 can display alphanumeric alarm and status messages on its single-line LCD display, as configured within the ProTool project.
Troubleshooting
Display remains blank after power on
Check that the 24 V DC supply voltage is present at the panel's power input terminals. Measure voltage directly at the connector to rule out wiring issues or blown fuses in the supply circuit.
Restore the 24 V DC supply if absent. Check and replace any blown fuses in the supply line. If supply voltage is confirmed correct and the display remains blank, the internal power supply or display unit may be faulty and require repair or replacement.
Panel shows communication error or 'PLC Not Responding' on startup
Verify the serial cable connections between the OP5 and the PLC. Check that the cable type matches the interface (TTY or RS-232) and that the baud rate, parity, and stop bits configured in ProTool match the PLC settings.
Correct any wiring faults or use the appropriate cable type. Align communication parameters in both the ProTool project and the PLC program. Re-download the project to the panel after making changes.
Panel enters transfer mode unexpectedly on power up
The panel may have been set to start in transfer mode, or a key combination was activated during boot. Check if the ProTool project has been successfully downloaded and stored in the panel memory.
Allow the ProTool software to complete a project download if intended. If transfer mode is not desired, restart the panel without triggering the transfer mode key sequence and verify the project is correctly stored in memory.
Operator input via keys is not accepted or keys appear unresponsive
Inspect the keypad membrane for physical damage, contamination, or wear. Verify that the panel project configuration includes the correct key assignments for the intended functions.
Clean the keypad surface if contamination is present. If keys are physically damaged, the keypad membrane assembly should be replaced. Review and correct key assignments in the ProTool project if the issue is configuration-related.
Project download from ProTool fails or times out
Check the serial cable connection between the PC and the OP5. Confirm the panel is in transfer mode and that the correct COM port and transfer settings are selected in ProTool on the PC.
Ensure the panel is in transfer mode before initiating the download. Use a known-good serial cable and verify the PC COM port is functioning correctly. Adjust the transfer settings in ProTool to match the panel's interface configuration and retry the download.
