Description
Additional information

The Siemens 6AV6355-1DA00-0DM4 is an Operator Panel (OP 177B) belonging to the SIMATIC HMI series, designed for machine-level human-machine interface applications. This panel provides a monochrome display with keypad-based operation and is part of Siemens' mid-range HMI portfolio. It is configured and programmed using WinCC flexible engineering software and integrates seamlessly into Siemens automation environments.

The OP 177B features a 5.7-inch STN monochrome display with a resolution of 320 x 240 pixels and a membrane keypad for operator input. It supports MPI, PROFIBUS DP, and Ethernet (PROFINET) communication interfaces, enabling flexible integration with SIMATIC S7 PLCs and third-party controllers. The panel includes 6 MB of user memory, supports recipe management, alarm logging, and trend displays, and operates on a 24 V DC supply. It carries a protection rating of IP65 on the front face, making it suitable for panel-mount installations in industrial environments.

The OP 177B is widely used in manufacturing, process automation, and machine building applications where a robust, keypad-operated HMI is required. It is commonly found on packaging machinery, conveyor systems, and general-purpose industrial machines where operators need to monitor process values, acknowledge alarms, and adjust setpoints. Its compatibility with the SIMATIC S7-200, S7-300, and S7-400 PLC families makes it a versatile choice across a broad range of automation projects.

Common Error Codes and System Events

Event ID: 10000: Configuration error detected during startup; the loaded project is incompatible with the panel firmware version.
Re-transfer the project using a compatible version of WinCC flexible. Ensure firmware and project versions match.
Event ID: 10001: Communication connection to the PLC has been lost or cannot be established.
Check MPI/PROFIBUS/Ethernet cabling and termination resistors. Verify PLC address settings and communication parameters in the project configuration.
Event ID: 10002: Tag read error; the HMI cannot read the specified PLC tag or address.
Verify the PLC tag address exists and is accessible. Check data block numbers and variable types in the WinCC flexible project.
Event ID: 10003: Tag write error; the HMI cannot write a value to the specified PLC address.
Confirm the PLC address is writable and not write-protected. Check data type compatibility between HMI tag and PLC variable.
Event ID: 10004: Recipe data transfer error; recipe could not be transferred to or from the PLC.
Check recipe configuration in WinCC flexible. Ensure the PLC data block referenced by the recipe exists and has sufficient size.
Event ID: 10005: Internal device error; a hardware or firmware fault has been detected on the panel.
Perform a panel restart. If the error persists, update the firmware using ProSave or WinCC flexible and contact Siemens support if unresolved.
Event ID: 10006: Backup/restore error; data backup or restore operation failed.
Check the storage medium (memory card) for errors or insufficient space. Reformat the card if necessary and retry the operation.
Event ID: 10007: Alarm buffer overflow; the number of pending alarms has exceeded the buffer capacity.
Acknowledge and clear existing alarms. Review alarm configuration to reduce unnecessary alarm triggers and increase buffer size if possible in the project settings.

Frequently Asked Questions

Which PLCs are compatible with the OP 177B (6AV6355-1DA00-0DM4)?

The OP 177B is compatible with SIMATIC S7-200, S7-300, and S7-400 PLCs via MPI or PROFIBUS DP, and also supports PROFINET communication for S7-300/400 with Ethernet capability. It can also communicate with a range of third-party controllers supported by WinCC flexible drivers.

What engineering software is required to program this panel?

The OP 177B is configured using Siemens WinCC flexible 2005 or a later version. Projects are transferred to the panel via MPI, PROFIBUS, Ethernet, or USB using the ProSave tool or directly from WinCC flexible.

What is the operating voltage for the 6AV6355-1DA00-0DM4?

The panel operates on a 24 V DC supply with a maximum power consumption of approximately 9 W.

What is the front panel protection rating of the OP 177B?

The front face of the OP 177B carries an IP65 protection rating, making it resistant to dust ingress and low-pressure water jets, suitable for panel-mount installations in industrial environments.

Does the OP 177B support data logging and recipe management?

Yes, the OP 177B supports recipe management, alarm logging, and trend displays. These functions are configured within WinCC flexible and stored in the panel's 6 MB user memory.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the panel's power connector. Check that the supply is within the specified tolerance and that the connector is fully seated.

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

Panel fails to communicate with the PLC

Verify the MPI or PROFIBUS cable connections and check that termination resistors are correctly installed at both ends of the bus. Confirm that the panel's bus address matches the configuration in WinCC flexible and does not conflict with other devices.

Correct any wiring faults, ensure proper bus termination, and adjust the panel address if necessary via the panel's Start Center settings. Re-transfer the project if communication parameters were changed.

Touchscreen or keypad inputs are not responding

Check whether the panel is in transfer mode or if a screensaver is active. Attempt to wake the panel by pressing any key. If keys are physically unresponsive, inspect the membrane keypad for damage or contamination.

Exit transfer mode via the Start Center if active. If the keypad is damaged or worn, the membrane keypad assembly should be replaced by a qualified technician.

Project transfer fails or times out

Verify the communication cable between the PC and the panel is correctly connected and that the panel is set to transfer mode via the Start Center. Check that the correct communication interface and baud rate are selected in WinCC flexible or ProSave.

Set the panel to transfer mode, select the correct interface and matching baud rate in the transfer settings, and retry. Replace the transfer cable if it is suspected to be faulty.

Alarm messages are displayed in incorrect language or with placeholder text

The project language settings in WinCC flexible may not match the runtime language configured on the panel, or the project was not fully compiled before transfer.

Recompile the project in WinCC flexible, ensure all alarm texts are entered for the required languages, and re-transfer the complete project to the panel.
