€ 395,00
The Siemens 6AG1647-0AA11-2AX0 is a SIPLUS HMI Touch Panel belonging to the TP177A series, part of the SIMATIC HMI product family. This unit is a ruggedized variant of the standard TP177A, designed for use in harsh industrial environments with extended temperature and contamination resistance. It serves as a compact operator interface panel for machine-level visualization and control tasks.
The TP177A features a 5.7-inch STN color display with a resolution of 320 x 240 pixels (QVGA) and resistive touch screen technology for reliable operator input. It communicates via MPI and PROFIBUS DP interfaces, enabling direct integration with Siemens S7-200, S7-300, and S7-400 PLCs. The panel runs on WinCC flexible runtime and supports configuration via WinCC flexible 2008 or later. It operates on a 24 V DC supply and is rated IP65 on the front face for protection against dust and water ingress.
The TP177A is widely deployed in manufacturing, automotive, food and beverage, and process industries for machine-level HMI applications. Its compact form factor and SIPLUS ruggedization make it suitable for installation in environments subject to condensation, corrosive atmospheres, or extended temperature ranges. It is commonly found on standalone machines, conveyor systems, and packaging equipment where a reliable and compact touch panel interface is required.

Common Error Codes & System Events
- Event ID: 1000
- Configuration error: The project loaded on the panel is incompatible with the current firmware version.
Reload a compatible project using WinCC flexible. Verify firmware version matches the project settings before transfer. - Event ID: 10000
- Communication error: Connection to the PLC has been lost or cannot be established.
Check MPI or PROFIBUS DP cable connections and termination resistors. Verify PLC address settings match the HMI project configuration. - Event ID: 10001
- Timeout error: No response received from the configured PLC within the timeout period.
Check network cabling, verify PLC is in RUN mode, and confirm baud rate and station address settings on both HMI and PLC. - Event ID: 20000
- Tag read error: A configured tag could not be read from the PLC.
Verify the tag address exists in the PLC program. Check data block numbers and variable addresses in the WinCC flexible project. - Event ID: 20001
- Tag write error: A value could not be written to the configured PLC tag.
Check PLC write protection settings and confirm the tag address is correct and writable in the PLC program. - Event ID: 40000
- System memory low: Available runtime memory on the panel is insufficient.
Reduce the number of active screens, limit logged data, or simplify the project. Consider archiving or deleting old data logs on the panel. - Event ID: 70010
- Backup battery low or missing: The internal backup battery voltage is below the required threshold.
Replace the internal backup battery. Refer to the TP177A operating instructions for battery replacement procedure.
Frequently Asked Questions
Which PLCs are compatible with the Siemens TP177A (6AG1647-0AA11-2AX0)?
The TP177A supports communication with Siemens S7-200, S7-300, and S7-400 PLCs via MPI and PROFIBUS DP interfaces. It can also communicate with S7-200 via PPI protocol.
What software is required to configure and program this HMI panel?
The TP177A is configured using Siemens WinCC flexible 2008 or a compatible version. Projects are transferred to the panel via MPI cable or a USB-to-MPI adapter.
What makes the SIPLUS 6AG1647-0AA11-2AX0 different from the standard TP177A?
The SIPLUS variant is designed for extended environmental conditions, including resistance to condensation, increased temperature ranges down to -20 °C, and exposure to corrosive or chemically aggressive atmospheres not covered by the standard version.
What is the supply voltage for this panel?
The panel requires a 24 V DC power supply. Ensure the supply is within the permissible voltage tolerance range as specified in the product manual.
Is the TP177A front panel rated for wash-down or dusty environments?
Yes, the front face of the TP177A is rated IP65, providing protection against dust ingress and low-pressure water jets, making it suitable for installation in dusty or moderately wet industrial environments.
Troubleshooting
Display remains blank after power on
Check that 24 V DC is present at the power supply terminals. Measure voltage at the panel connector and verify polarity. Inspect internal fuse if accessible.
Restore correct 24 V DC supply. If voltage is present but display remains off, the internal power supply board or backlight may be faulty and the unit should be sent for repair or the backlight replaced.
Touch screen does not respond or responds inaccurately
The resistive touch screen may be miscalibrated or the touch surface may be damaged. Check for physical damage, contamination, or worn touch overlay.
Perform a touch screen recalibration via the panel's Start Center or Control Panel settings. If calibration does not resolve the issue, the touch screen overlay may need replacement.
HMI cannot establish communication with the PLC
Verify MPI or PROFIBUS DP cable connections, termination resistors at both ends of the bus, and that the station addresses configured in the HMI project match the PLC settings.
Correct any address mismatches in the WinCC flexible project. Replace faulty cables or connectors. Ensure bus termination is active only at the two physical ends of the network.
Panel repeatedly reboots or freezes during operation
This may indicate a corrupted project file, insufficient runtime memory, or a hardware fault. Check event logs in the panel's Start Center for error entries.
Reload the project from WinCC flexible. If the issue persists after reloading, perform a factory reset via the Start Center and re-transfer the project. If reboots continue, the panel hardware may require servicing.
Project transfer fails from engineering PC to panel
Check the MPI cable or USB-to-MPI adapter driver installation on the PC. Verify the transfer channel settings in WinCC flexible match the physical connection type and baud rate.
Reinstall or update the PC adapter driver. Confirm the panel is in Transfer mode via the Start Center. Try a different MPI cable or adapter if the issue persists.
