€ 1.995,00
The Siemens 6AV6341-1BA04-0AY0 is an OP 177B operator panel belonging to the SIMATIC HMI family of human-machine interface devices. This unit provides a monochrome STN display and is designed for machine-level visualization and operator control tasks. It is part of the SIMATIC HMI Comfort and Mobile Panel generation and is configured and operated using WinCC flexible or TIA Portal engineering software.
The OP 177B features a 5.7-inch STN monochrome display with a resolution of 320 x 240 pixels and includes both a touch screen and function keys for operator input. It supports MPI, PROFIBUS DP, and Ethernet (PROFINET) communication interfaces, enabling integration into a wide range of Siemens PLC environments including S7-200, S7-300, and S7-400 controllers. The panel provides 512 KB user memory for project data and supports recipe management, alarm logging, and trend display functions. It operates on 24 V DC supply voltage and is rated IP65 on the front face for protection against dust and water ingress.
The OP 177B is widely deployed in manufacturing, machine building, and process automation environments where a compact, robust operator interface is required at the machine level. Its combination of touch and key-based input makes it suitable for applications where gloved operation or harsh environmental conditions are a consideration. Typical installations include conveyor systems, packaging machinery, injection molding machines, and general-purpose industrial automation panels.

Common Error Codes and System Events
- Event ID: 10000
- Configuration error detected during startup; project data on the device is corrupted or incompatible.
Re-transfer the project from WinCC flexible or TIA Portal to the device. Ensure the software version matches the panel firmware version. - Event ID: 20000
- Communication error on MPI or PROFIBUS DP interface; connection to the PLC has been lost.
Check MPI/PROFIBUS cable connections and termination resistors. Verify PLC address settings and bus configuration in the project. - Event ID: 40000
- Ethernet/PROFINET communication fault; the panel cannot establish a connection to the configured network node.
Verify IP address configuration on both the panel and the PLC. Check Ethernet cable and switch/hub connectivity. - Event ID: 70000
- Internal device error; a hardware fault has been detected within the panel.
Perform a device restart. If the fault persists, the panel may require repair or replacement of internal components. - Event ID: 50000
- Tag read/write error; the panel cannot access a configured PLC data address.
Verify that the PLC program contains the correct data blocks and addresses referenced in the HMI project. Check PLC run state. - Event ID: 30000
- Project transfer error; data transfer between the engineering PC and the panel was interrupted or failed.
Check the transfer cable or network connection. Ensure the panel is in Transfer mode and retry the project download. - Event ID: 60000
- Alarm buffer overflow; the number of pending alarms exceeds the panel buffer capacity.
Acknowledge and clear active alarms. Review the alarm configuration in the project to reduce simultaneous alarm occurrences.
Frequently Asked Questions
What communication interfaces does the OP 177B (6AV6341-1BA04-0AY0) support?
The OP 177B supports MPI, PROFIBUS DP, and Ethernet (PROFINET) interfaces, allowing connection to Siemens S7-200, S7-300, and S7-400 PLCs as well as third-party controllers via appropriate drivers.
Which engineering software is used to configure the OP 177B?
The OP 177B is configured using Siemens WinCC flexible 2008 or later, or alternatively via the TIA Portal with the appropriate HMI configuration package. Projects are transferred to the panel via MPI, PROFIBUS, or Ethernet.
What is the supply voltage for the 6AV6341-1BA04-0AY0?
The panel operates on a 24 V DC supply voltage. Ensure the power supply can deliver sufficient current, as the panel draws up to approximately 9 W under normal operating conditions.
Is the OP 177B front panel rated for wash-down or dusty environments?
Yes, the front face of the OP 177B carries an IP65 protection rating, making it suitable for environments with dust and water spray. The rear of the unit is rated IP20.
Can the OP 177B be used with S7-1200 or S7-1500 PLCs?
The OP 177B can communicate with S7-1200 and S7-1500 PLCs via Ethernet/PROFINET, provided the HMI project is configured correctly in WinCC flexible or TIA Portal with the appropriate PLC driver selected.
Troubleshooting
Display remains blank after power is applied
Measure the 24 V DC supply voltage at the panel power connector. Check that the voltage is within the specified tolerance. Inspect the internal fuse if accessible.
Correct the supply voltage if out of range. If voltage is correct and the display remains blank, the backlight or internal power board may be faulty and the unit should be sent for repair.
Panel fails to communicate with the PLC via PROFIBUS DP
Check the PROFIBUS cable for continuity and correct termination at both ends of the bus. Verify the panel PROFIBUS address matches the address configured in the HMI project and PLC hardware configuration.
Replace or re-terminate the PROFIBUS cable if damaged. Correct address mismatches in the project configuration and re-download the project to the panel.
Touchscreen does not respond or registers incorrect touch positions
Clean the touch surface and check for physical damage or contamination. Attempt a touchscreen calibration from the panel's Start Center or Control Panel menu.
Perform touchscreen recalibration via the panel's operating system menu. If calibration does not resolve the issue, the touch overlay may be damaged and require replacement.
Project transfer from PC to panel fails repeatedly
Verify the panel is set to Transfer mode via the Start Center. Check the communication cable or Ethernet connection between the engineering PC and the panel. Confirm that the WinCC flexible project version is compatible with the panel firmware.
Set the panel to Transfer mode, replace the communication cable if faulty, and ensure the engineering software version matches the panel firmware. Update panel firmware if a version mismatch is identified.
Alarms are not displayed or alarm history is missing
Check the alarm configuration in the HMI project to confirm alarm tags are correctly linked to PLC addresses. Verify the PLC is in RUN mode and the relevant alarm bits are being set correctly.
Correct any misconfigured alarm tag addresses in the WinCC flexible project and re-transfer the project to the panel. Confirm PLC logic is correctly setting alarm trigger bits.
