More Information

Overview Manuals Screen Workspace Alarm and Recipe Data Open Communication Installation Limits

Features:

  • A 9-inch touchscreen, ten illuminated function keys, and touch-direct keys form the mobile controls.
  • PROFINET, USB 2.0, and an SD-card slot provide independent communication and storage routes.
  • Alarm, recipe, archive, script, user, and OPC UA functions operate within the configured runtime.
The 6AV2125-2JB03-0AX0 is the standard KTP900 Mobile panel rather than a PROFIsafe-equipped F version.

Its physical keys can remain assigned to recurring operations while the touchscreen changes between project views.

All-round IP65 protection applies when the documented connectors, covers, cable handling, and operating limits are maintained.

The Siemens 6AV2125-2JB03-0AX0 SIMATIC HMI KTP900 Mobile Operator Panel may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Project Visualization and Key Input

  • Canvas: A 9-inch color TFT displays the project at 800 x 480 pixels.
  • Persistent commands: Ten illuminated hardware keys remain available as screens change.
  • Fast input: The configuration can assign 32 touch-direct keys.
  • Entry method: Onscreen keyboards accept numerical and alphanumerical values.

Runtime Information Handling

  • Messages: Discrete and analog alarm classes report configured process states.
  • Setpoints: Recipe records organize related operator-entered values.
  • History: Archive functions record selected tags and messages to an assigned destination.
  • Authorization: User groups restrict project actions according to configured rights.

Ethernet Services and Protocol Roles

  • Automation link: The network connector carries PROFINET controller communication.
  • Interoperability: Modbus and EtherNet/IP functions are available in supported projects.
  • Information model: OPC UA client and server roles exchange configured process data.
  • Interface limit: No PROFIBUS or separate serial channel is built into this ordering code.

Supply and Mobile-Use Conditions

  • Input power: The unit operates from 24 V DC within 19.2 to 28.8 V DC.
  • Enclosure: All-round IP65 protection requires correctly closed covers and connected hardware.
  • Ambient range: Published operation extends from 0 to 45 °C.
  • Mechanical event: The documented free-fall height is 1.2 m.
Description
Process values and manual commands are presented by Siemens 6AV2125-2JB03-0AX0, the standard 9-inch KTP900 Mobile panel in the second-generation SIMATIC HMI range. This ordering code does not include the enabling device, emergency control, or PROFIsafe channel found on an F-version panel.

Across the front of 6AV2125-2JB03-0AX0, an 800 x 480 color screen handles touch interaction while ten illuminated keys retain project-assigned hardware commands. A project can also use 32 touch-direct keys for input that is evaluated independently of ordinary screen-object operation.

Ethernet is the controller and service backbone for 6AV2125-2JB03-0AX0. The single network port supports PROFINET plus documented TCP/IP, Modbus, EtherNet/IP, and OPC UA functions; USB and SD media remain available for local transfer and data handling, but there is no serial fieldbus port.

Within 6AV2125-2JB03-0AX0, 12 MB of user memory serves multilingual screens, messages, recipes, archives, scripts, and authorization data. A 24 V DC supply powers the unit, and the IP65 enclosure, 0 to 45 °C range, and 1.2 m fall rating define its mobile-use limits.
