Description
Additional information

The Siemens 6AV6646-1BA22-1NA1 is a SIMATIC KTP400 Basic panel, part of the Basic Panel 2nd Generation (PN) series from Siemens. It is a compact 4-inch key and touch-operated HMI panel designed for straightforward visualization and operator control tasks. This unit communicates via PROFINET and is configured using the WinCC Basic engineering software included with TIA Portal.

The KTP400 Basic features a 4.3-inch widescreen TFT display with a resolution of 480 x 272 pixels and 64,000 color support, providing clear process visualization. It includes 4 configurable function keys and a resistive touch screen for operator input. The panel operates on a 24 V DC supply and offers 10 MB of user memory for project data. Communication is handled via a single PROFINET (RJ45) interface, enabling integration into standard Ethernet-based automation networks.

The SIMATIC KTP400 Basic is widely used in small to medium-scale machine automation across industries such as packaging, material handling, food and beverage, and general manufacturing. Its compact form factor and cost-effective design make it suitable for applications where basic process monitoring and operator interaction are required without the need for advanced panel functionality. It is typically paired with Siemens S7-1200 and S7-1500 PLCs within TIA Portal-based automation architectures.

Common Error Codes & System Events

Event ID: 10000: Configuration error detected on the HMI panel, project data may be corrupt or incompatible with the panel firmware version.
Re-download the project from TIA Portal ensuring the firmware version matches the configured panel version. Perform a factory reset if necessary.
Event ID: 20000: Communication connection to the PLC has been lost or cannot be established via PROFINET.
Check PROFINET cable and RJ45 connector integrity. Verify IP address configuration of both the panel and PLC. Confirm the PLC is in RUN mode.
Event ID: 40000: Tag read/write error — the HMI cannot access a configured PLC tag or data block.
Verify the tag address in TIA Portal matches the actual PLC data block structure. Check PLC program for deleted or renamed tags.
Event ID: 50000: System memory low — available user memory on the panel is insufficient for the loaded project.
Reduce project size by optimizing graphics, removing unused screens or tags, and recompile and re-download the project.
Event ID: 70000: Firmware update error — firmware transfer to the panel was interrupted or failed.
Retry the firmware update via TIA Portal or ProSave. Ensure stable power supply and communication connection during the update process.
Event ID: 110000: Panel operating system error or internal watchdog timeout detected.
Perform a controlled restart of the panel. If the error persists, execute a factory reset using the Start Center and reload the project.

Frequently Asked Questions

Which engineering software is required to configure the KTP400 Basic 6AV6646-1BA22-1NA1?

This panel is configured using Siemens TIA Portal with WinCC Basic, version V13 SP1 or higher. Standalone STEP 7 or WinCC flexible is not compatible with this panel generation.

Which Siemens PLCs are compatible with this HMI panel?

The KTP400 Basic communicates via PROFINET and is primarily designed for use with Siemens S7-1200 and S7-1500 PLCs. It can also communicate with S7-300 and S7-400 PLCs via PROFINET with appropriate configuration in TIA Portal.

What is the communication interface on the 6AV6646-1BA22-1NA1?

The panel is equipped with a single PROFINET interface (RJ45 connector) supporting 10/100 Mbit/s Ethernet. It does not have a MPI, PROFIBUS, or serial interface.

Can the KTP400 Basic panel be used outdoors?

The front of the panel carries an IP65 protection rating, making it resistant to dust and water jets, but it is not rated for direct outdoor exposure to UV radiation or extreme weather. It should be installed in an enclosure suitable for the environmental conditions.

What is the user memory capacity of this panel?

The KTP400 Basic 6AV6646-1BA22-1NA1 provides 10 MB of user memory for storing project data, screens, and tag configurations.

Troubleshooting

Display remains blank after power is applied

Measure the 24 V DC supply voltage at the panel power connector. Check that polarity is correct and voltage is within the 20.4–28.8 V DC tolerance range.

Correct the supply voltage or wiring polarity. If voltage is correct and display remains blank, the internal power supply or backlight may be faulty and the panel should be sent for repair or replacement.

Panel shows 'No connection to PLC' or communication alarm on startup

Verify the PROFINET IP address assigned to the panel in TIA Portal matches the address configured in the Start Center. Check the RJ45 cable and network switch for link activity LEDs.

Correct the IP address configuration in TIA Portal or via the panel Start Center. Replace the PROFINET cable if no link is detected. Ensure the PLC is powered and in RUN mode.

Touch screen does not respond or responds inaccurately to input

Check for physical damage or contamination on the touch screen surface. Verify that the operator is not using gloves incompatible with resistive touch technology.

Clean the touch screen surface with a soft, dry cloth. Recalibrate the touch screen via the panel Start Center under 'Settings'. If calibration does not resolve the issue, the touch panel assembly may require replacement.

Project download from TIA Portal fails or times out

Check the PROFINET connection between the engineering PC and the panel. Verify that the panel is in transfer mode via the Start Center and that no firewall is blocking TIA Portal communication.

Set the panel to transfer mode manually via Start Center > Transfer. Disable PC firewall temporarily during download. Ensure the TIA Portal project panel type and firmware version match the physical panel.

Panel repeatedly restarts or enters a boot loop

This may indicate a corrupted project file on the panel or a firmware mismatch. Observe whether the panel reaches the Start Center before restarting.

Access the Start Center during boot by pressing the touch screen during startup. Perform a factory reset from the Start Center and re-download a freshly compiled project from TIA Portal. Update firmware if a mismatch is detected.
