SIMATIC HMI KTP700 Basic DP article 6AV2123-2GA03-0AX0 is a second-generation Basic Panel for machine-level visualization and operator control. It combines an analog-resistive touchscreen with eight function keys.

The seven-inch LED-backlit TFT provides 800 × 480 pixels and 65,536 colors. This GA03 variant communicates through PROFIBUS and is engineered with WinCC Basic V13 or STEP 7 Basic V13 and later supported versions.

• Presents machine values, status messages, alarms and operator dialogs on a seven-inch color display.
• Transfers commands through the resistive touchscreen and eight physical function keys.
• Exchanges process data with compatible controllers over PROFIBUS.
• Stores the configured HMI project and up to 10 MB of user data.
• Supports cabinet-door operation in portrait or landscape orientation within the permitted installation conditions.

• The 2GA03 article is the DP model and must not be confused with the 2GB03 PROFINET KTP700 Basic.
• Use WinCC Basic V13 or STEP 7 Basic V13 and a supported later release for project engineering.
• Confirm the existing PROFIBUS address, bus connector, baud rate and controller configuration before exchange.
• Retain the original HMI project, recipes, user data, passwords and device image information.
• Verify the mounting cutout and external wiring before considering another KTP700 family variant.

• Operator panels for PROFIBUS-connected compact machines.
• Alarm, status and setpoint visualization at packaging or material-handling equipment.
• Retrofits that retain an existing KTP700 Basic DP project and cabinet cutout.
• Stations where touch navigation and dedicated function keys are both required.
• Machine interfaces using 24 V DC panel power and an established PROFIBUS segment.

Does 6AV2123-2GA03-0AX0 use PROFINET or PROFIBUS?

It is the KTP700 Basic DP version and uses a PROFIBUS interface.

What is the display resolution?

The seven-inch widescreen display provides 800 × 480 pixels.

How many physical function keys are available?

Eight function keys are provided in addition to the touchscreen.

Can the 2GB03 KTP700 Basic replace it without network changes?

No. The 2GB03 article is the PROFINET version, so network hardware and engineering differ.

Which engineering release first supports this panel?

It is configurable from WinCC Basic V13 or STEP 7 Basic V13.

What must be saved before panel exchange?

Save the complete HMI project, recipes, user data, passwords, PROFIBUS settings and panel image information.
