Siemens 6AV6647-0AK11-3AX0 KTP400 Basic PN

Siemens 6AV6647-0AK11-3AX0 KTP400 Basic PN Panel

The Siemens 6AV6647-0AK11-3AX0 belongs to the SIMATIC HMI Basic series. This KTP400 model is one of the smallest panels in the family. Nevertheless, it offers both touch and key operation for flexible use.

Display and Visual Performance

This HMI uses a 4.3-inch TFT widescreen display. Screen resolution reaches 480 x 272 pixels, shown in red text. Display width measures 95 mm, and height measures 53.8 mm.

Color depth equals 256 colors, highlighted in red text. This provides basic but clear graphics for simple applications. The backlight lasts 50,000 hours at 25°C, which is longer than many larger panels.

However, backlight dimming is not available on this model. Therefore, the brightness stays at a fixed level throughout operation.

Control Elements and Touch Function

The 6AV6647-0AK11-3AX0 features four physical function keys. None of these keys include built-in LEDs. System keys are not present on this model.

Touch operation uses resistive technology. An onscreen keyboard appears for numeric or alphanumeric input. As a result, you can enter data without external devices.

A built-in buzzer provides audible feedback for key presses and alarms. This helps operators confirm their inputs without looking at the screen.

Installation Flexibility

You can mount this panel vertically or horizontally. Portrait format and landscape format are both supported, noted in red text. Maximum tilt angle without external ventilation is 35 degrees.

Vertical installation works between 0°C and 50°C. However, portrait orientation limits the top temperature to 40°C. For tilted installation in portrait mode, the maximum drops to 35°C.

The panel is extremely compact. Front housing measures only 140 mm wide by 116 mm high. Mounting cutout size is 123 mm x 99 mm.

Power Requirements

Power supply must be 24V DC. The acceptable range spans 19.2V to 28.8V. Current consumption is only 0.1 A (100 mA), shown in red text.

Inrush current I²t equals 0.5 A²·s. Active power consumption is just 2 W. Therefore, this is one of the most energy-efficient HMI panels available.

Memory and Processor

A 32-bit RISC ARM processor runs the system. Flash and RAM memory are both included. User data memory equals 1 Mbyte, highlighted in red text.

No USB port, SD card slot, or RS485 interface is present on this model. Consequently, all project transfers must go through Ethernet.

Connectivity and Interfaces – PROFINET Only

The Siemens 6AV6647-0AK11-3AX0 includes one industrial Ethernet port. Two Ethernet status LEDs help with diagnostics. No other physical interfaces are available.

PROFINET is the main communication protocol. Modbus TCP/IP and EtherNet/IP are also supported. PROFIBUS and MPI are not available.

Supported Protocols and PLC Coupling

TCP/IP, DHCP, SNMP, DCP, and LLDP all work over Ethernet. MRP (Media Redundancy Protocol) is not supported.

For PLC connections, it works with Siemens S7-1200, S7-1500, S7-300/400, S7-200, and LOGO!. Additionally, Modicon (Modbus TCP/IP) and Allen Bradley (EtherNet/IP) are supported.

Environmental Ratings

The front panel carries an IP65 rating, highlighted in red text. NEMA Type 4 is also approved for the front. The rear panel rating is not specified but typically IP20 for basic panels.

Operating humidity can reach 90% without condensation. Storage temperature ranges from -20°C to 60°C. This panel is for indoor use only.

Hazardous area approvals are not available for this model. Marine approvals are also not listed in the datasheet.

Configuration Requirements

You need WinCC Basic V11 SP2 or higher from TIA Portal. STEP 7 Basic V11 SP2 also includes the required software. WinCC flexible is not compatible with this panel.

Online runtime supports multiple languages, though the official datasheet does not specify the exact number. A real-time hardware clock is not present. Instead, the panel uses a software clock.

Backup and Transfer

Project transfer happens only over PROFINET (Ethernet). USB transfer is not available because no USB port exists. Backup and restore functions are supported manually.

No SD card slot means external storage is not possible. Therefore, keep your project files safe on your engineering PC.

Frequently Asked Questions (FAQ)

1. Does the 6AV6647-0AK11-3AX0 have a USB port?
No, this panel has no USB port. All project transfers must use the Ethernet (PROFINET) port.

2. Can I connect this panel to a S7-200 PLC?
Yes, it works with S7-200 via PROFINET. However, the S7-200 needs an Ethernet module like the CP243-1.

3. What is the memory size for user data?
User data memory is 1 Mbyte, shown in red text. This is sufficient for small to medium projects with limited graphics.

4. Is the backlight replaceable?
The backlight is not user-replaceable. However, its rated lifespan is 50,000 hours at 25°C, which equals about 5.7 years of continuous use.

5. Can I use this panel outdoors?
No, it is for indoor use only. The operating temperature range is 0°C to 50°C. Direct sunlight may also reduce visibility.
