Description
Additional information

The Siemens 6AV6244-1BC10-0BX0 is an OP 177B operator panel belonging to the SIMATIC HMI family of human-machine interface devices. This unit provides a monochrome STN LCD display and is designed for machine-level visualization and operator control in industrial environments. As part of the SIMATIC HMI Comfort and Basic panel generation predecessor series, it is engineered for reliable operation in demanding production settings.

The OP 177B features a 5.7-inch monochrome display with a resolution of 320 x 240 pixels and supports touch and key-based operation through its integrated membrane keypad. It is equipped with MPI/PROFIBUS DP and RS-422/RS-485 interfaces for PLC connectivity, and includes a USB port for project transfer and data backup. The panel runs on WinCC flexible runtime and supports configuration via Siemens WinCC flexible engineering software, with onboard flash memory for project and recipe storage.

The OP 177B is widely used in machine building, automotive manufacturing, food and beverage processing, and general factory automation. It is particularly suited for applications requiring a compact, robust operator interface with direct connectivity to SIMATIC S7-300 and S7-400 PLCs, as well as third-party controllers via serial communication. Its keypad-based operation makes it appropriate for environments where touchscreen use may be impractical due to gloves or contamination.

Common Error Codes and System Events

Event ID: 1000: Configuration error detected during startup; project data may be corrupt or incompatible with the firmware version.
Re-transfer the project using WinCC flexible. Ensure the firmware version on the panel matches the WinCC flexible version used for configuration.
Event ID: 10000: Communication error with the configured PLC; connection to the controller cannot be established.
Check MPI/PROFIBUS DP cable connections and termination resistors. Verify the PLC address and baud rate settings match the panel configuration.
Event ID: 10001: Tag read error; the panel cannot read a configured tag from the PLC.
Verify the tag address in the WinCC flexible project matches the actual PLC data block or memory address. Check PLC program is running.
Event ID: 20000: System memory low; available runtime memory is insufficient for current project operations.
Reduce the number of active screens, alarms, or recipe entries. Consider simplifying the project or upgrading to a panel with greater memory capacity.
Event ID: 40000: Backup battery low or missing; the internal buffer battery voltage is below threshold.
Replace the internal buffer battery with the correct Siemens replacement type. Perform a project backup before replacement to avoid data loss.
Event ID: 50000: USB device error; a connected USB device is not recognized or communication has failed.
Remove and reinsert the USB device. Ensure the USB storage device is formatted as FAT32 and is compatible with the panel.
Event ID: 70000: Firmware update error; the firmware transfer to the panel was interrupted or the firmware file is invalid.
Restart the firmware update process using the correct firmware file for the OP 177B. Ensure stable power supply during the update procedure.

Frequently Asked Questions

Which PLCs are compatible with the OP 177B (6AV6244-1BC10-0BX0)?

The OP 177B is primarily designed for use with Siemens SIMATIC S7-300 and S7-400 PLCs via MPI or PROFIBUS DP. It also supports connectivity to S7-200 PLCs and selected third-party controllers via RS-422/RS-485 serial communication.

What software is required to configure and program this panel?

The OP 177B is configured using Siemens WinCC flexible 2008 or later. Projects are transferred to the panel via MPI, PROFIBUS DP, or USB connection.

What is the supply voltage for the 6AV6244-1BC10-0BX0?

The panel requires a 24 V DC supply voltage. Ensure the power supply can deliver sufficient current to meet the panel's maximum power consumption of 9 W.

Can the OP 177B display color graphics?

No, the OP 177B features a monochrome STN LCD display and does not support color graphics. It is capable of displaying blue/white monochrome content only.

What is the front panel protection rating of this unit?

The front panel of the OP 177B carries an IP65 protection rating, making it suitable for panel-mount installations where dust and water spray protection is required.

Troubleshooting

Display remains blank after power on

Check the 24 V DC supply voltage at the power connector. Verify the supply polarity is correct and the voltage is within the specified range. Inspect the internal fuse if accessible.

Restore correct 24 V DC supply. If the supply is confirmed correct and the display remains blank, the internal power supply board or backlight may have failed and the unit should be sent for repair or replacement.

Panel displays 'No connection to PLC' or communication errors at startup

Inspect the MPI or PROFIBUS DP cable for damage, loose connectors, and correct termination at both ends of the bus. Verify the PLC address and baud rate configured in WinCC flexible match the actual PLC settings.

Correct cable connections and termination. Adjust the communication parameters in the WinCC flexible project to match the PLC configuration, then re-transfer the project to the panel.

Touchscreen does not respond or responds inaccurately

Check whether the touch area is physically damaged or contaminated. Attempt a touchscreen recalibration from the panel's Start Center or control panel settings.

Clean the display surface with a soft, dry cloth. Perform a touchscreen calibration via the panel's operating system settings. If calibration fails repeatedly, the touch foil may be damaged and require hardware repair.

Project transfer via USB fails or is not recognized

Verify the USB storage device is formatted as FAT32 and that the project file is placed in the correct directory as required by WinCC flexible. Check that the USB device is not write-protected.

Reformat the USB device as FAT32, copy the project file to the root or correct subdirectory, and retry the transfer. If the USB port is unresponsive, attempt transfer via MPI or PROFIBUS DP instead.

Panel repeatedly restarts or enters a boot loop

This may indicate a corrupt project file, incompatible firmware, or a hardware fault. Attempt to access the Start Center by holding the appropriate key combination during boot to prevent automatic project loading.

Access the Start Center and perform a factory reset or re-transfer a known-good project. If the issue persists after project re-transfer, update the panel firmware to the latest compatible version for the OP 177B.
