KTP900 Basic, article 6AV2123-2JB03-0AX0, is a second-generation SIMATIC Basic Panel intended for machine-level operator control. Its larger 9-inch widescreen preserves the 800 x 480 project resolution while offering a 198.0 x 111.7 mm active display area.

The panel combines an analog-resistive touchscreen, eight configurable keys, a PROFINET interface and USB support. It is designed for 24 V DC cabinet installation and can be configured from WinCC Basic V13 onward.

• Presents machine data on a 9-inch widescreen while retaining the familiar Basic Panel engineering range.
• Combines analog-resistive touch input with eight configurable function keys.
• Supports one 10/100 Mb/s Ethernet connection for PROFINET-based controller communication.
• Allows portrait or landscape installation for flexible cabinet-door design.
• Provides manual backup and restore, simulation and project transfer functions.
• Supports USB storage and Modbus TCP/IP in addition to the defined SIMATIC controller connections.

• Machine interfaces requiring a larger viewing area than a seven-inch panel without moving to a 12-inch resolution class.
• Operator stations for alarms, recipes, setpoint entry and maintenance screens.
• PROFINET-connected packaging, assembly, pumping and material-handling systems.
• Retrofits that preserve an existing KTP900 Basic cutout and WinCC Basic project.
• Panels that benefit from both direct touch navigation and fixed-key operation.

• Article 6AV2123-2JB03-0AX0 is listed in the PM300 active product phase.
• Retain the complete project archive, image version, user data, passwords and Ethernet settings.
• Confirm the 251 x 166 mm cutout and 39.4 mm mounting depth before fitting another panel family.
• Do not treat KTP900 Basic Keyless OEM or KTP900 Mobile as the same hardware.
• Commission the touchscreen, function keys, alarms, tags, recipes and controller links after replacement.
