The Siemens SIMATIC HMI KTP600 Basic Color DP (6AV6647-0AC11-3AX0) is an industrial human-machine interface designed for machine operation, process visualization, and monitoring in PLC-based automation systems. It features a 5.7-inch TFT color display with touchscreen and six physical function keys, allowing operators to view machine status, monitor process values, acknowledge alarms, and interact with configured control screens.

This model supports MPI/PROFIBUS DP communication for integration with compatible Siemens PLCs and automation equipment. Its 320 × 240 pixel resolution and 256-color display are suitable for established industrial applications that require a compact operator interface.

The KTP600 Basic Color DP is an older-generation Siemens HMI. Before purchasing it for a new installation or as a replacement, verify the communication interface, project compatibility, and engineering software requirements.

Technical Specifications

Key Features and Benefits

• 5.7-inch TFT display: Provides a compact visual interface for machine operation and process monitoring.

• Touchscreen operation: Allows operators to interact directly with configured HMI screens.

• Six physical function keys: Provides convenient access to assigned machine functions.

• MPI/PROFIBUS DP connectivity: Supports communication with compatible PLCs and automation systems.

• Alarm and process visualization: Displays configured process values, messages, and machine status.

• Legacy system support: Can be considered for maintenance or replacement of compatible installations.

Applications

• PLC-controlled industrial machinery

• Factory production and assembly lines

• Packaging and material-handling equipment

• Process monitoring and alarm visualization

• Industrial machine operator stations

• Maintenance of existing Siemens automation systems

Compatibility and Installation

Before ordering, confirm that your PLC supports the MPI/PROFIBUS DP interface and that the existing HMI project can be configured with available Siemens engineering software. Check the panel dimensions, mounting cutout, power requirements, and cable connections against the official documentation.

Do not assume that a PROFINET-only replacement will connect directly to the same network or use the same project without additional changes. Installation and commissioning should be performed by qualified personnel.

Product Availability

According to Siemens Industry Mall, this article was cancelled effective 22 February 2022, with 6AV6647-0AC11-3AX1 listed as its successor. Availability of the original model may therefore depend on remaining stock or specialist spare-parts suppliers. Confirm condition, warranty, and delivery time before purchasing.
