Product Overview
The Siemens 6AV2124-0JC01-0AX0 is a SIMATIC HMI TP900 Comfort Panel used for machine visualization, process monitoring, and operator interaction in industrial automation systems. Its 9-inch widescreen touchscreen provides a local interface for viewing process values, navigating machine functions, acknowledging alarms, and entering operating parameters.
As part of the SIMATIC Comfort Panel family, the TP900 Comfort supports more extensive visualization and diagnostic functions than a basic status terminal. Its 800 × 480 pixel TFT display with 16 million colors allows machine builders to organize equipment graphics, numerical measurements, alarm lists, and operating controls into structured screens. The touchscreen supports direct interaction without a separate physical function-key arrangement.
The panel includes PROFINET and MPI/PROFIBUS DP communication interfaces, allowing it to connect to compatible Siemens controllers and supported automation systems. Its 12 MB configuration memory accommodates the HMI project, while Windows CE 6.0 provides the embedded operating environment. The panel can be configured using WinCC Comfort V11 or compatible later engineering software.
In a production facility, the TP900 Comfort can serve as the main operator station for a packaging machine, conveyor system, or process skid. Operators can switch between equipment overview screens, examine alarm messages, view process trends, and enter authorized setpoints. The PLC continues to execute the control logic, evaluate operating conditions, and manage the connected machinery.
The TP900 Comfort is also suitable for installations where the HMI must communicate with established automation equipment using MPI or PROFIBUS DP rather than relying exclusively on Ethernet-based communication. This can be useful when upgrading an existing machine or integrating an operator panel into a control architecture that already contains compatible Siemens devices.
The 6AV2124-0JC01-0AX0 therefore combines graphical operator interaction with industrial communication and engineering-software integration. Its practical value depends on a well-structured HMI project, correctly mapped controller variables, and an operating interface that reflects the actual machine sequence.

Working Principle
The TP900 Comfort functions as the visualization and operator-interaction layer of a PLC-based automation system. It receives process data from the controller, presents that information through the configured HMI project, and communicates operator actions back to the control system.
Field Instruments → PLC → PROFINET or MPI/PROFIBUS DP → TP900 Comfort → Operator
During engineering, the machine builder creates the HMI project using compatible WinCC Comfort software. Screens are configured with process indicators, numerical displays, buttons, input fields, alarm views, and navigation elements. Each relevant object is linked to a controller variable or an HMI function.
When the machine is running, the panel reads configured values from the controller and updates the display. For example, a conveyor-control screen may show motor status, line speed, production count, and active faults. Operators can move between screens to inspect individual conveyor sections or access maintenance information.
When an operator changes a permitted setpoint or presses a configured command button, the panel transfers the corresponding action through the established communication connection. The PLC then evaluates the request against its program, interlocks, and current machine conditions. The HMI does not independently determine whether a motor, valve, or other machine component should operate.
Alarm handling provides another important part of the panel’s operation. The HMI can display configured fault messages, identify the affected equipment, and provide access to related diagnostic screens. This helps maintenance personnel investigate a fault without relying exclusively on indicator lamps or external diagnostic equipment.
Correct operation depends on the complete data path. Controller addressing, communication settings, HMI tag definitions, data types, and scaling must agree with the PLC program. During commissioning, engineers should verify displayed values against known controller values and test each configured operator command under controlled conditions.
Role in a Siemens SIMATIC HMI Control Architecture
The TP900 Comfort occupies the operator-interface layer between production personnel and the automation system. It provides the screens and controls used to interact with the machine, while the PLC processes signals and executes the control sequence.
Field Sensors and Actuators → SIMATIC PLC → Industrial Communication Network → TP900 Comfort Panel → Operator
| System Component | Function |
|---|---|
| Siemens 6AV2124-0JC01-0AX0 | Provides graphical visualization and configured operator interaction |
| SIMATIC PLC | Executes machine logic, operating sequences, and interlocks |
| PROFINET Network | Transfers data between compatible controllers and networked devices |
| MPI/PROFIBUS DP Network | Supports communication with compatible automation equipment |
| Digital Input Module | Acquires discrete sensor and equipment states |
| Analog Input Module | Acquires supported process measurement signals |
| Motor Starter or Drive | Controls motor operation according to the machine design |
| Pressure Transmitter | Supplies pressure measurements to the controller |
| Temperature Sensor | Provides temperature information for monitoring or control |

The division of responsibilities is important: the HMI displays information and communicates operator requests, whereas the PLC remains responsible for executing the machine-control program. Safety functions must be implemented in the appropriate safety-related architecture rather than relying solely on ordinary HMI commands.

Technical FAQs
How does the TP900 Comfort handle communication with older Siemens PLC systems?
The panel includes an MPI/PROFIBUS DP interface for compatible automation architectures. The PLC model, supported communication protocol, addressing, and HMI driver configuration must match the intended connection.
What can be displayed on a TP900 Comfort screen?
A configured project can display process values, equipment states, alarm messages, trends, recipes, and operator controls. The available information depends on the HMI project, controller variables, and configured visualization objects.
Can the TP900 Comfort communicate with a non-Siemens controller?
Yes, supported third-party controllers can be connected through available communication drivers and protocols, including compatible EtherNet/IP and Modbus implementations. The specific controller and protocol configuration determine whether the required data exchange is supported.
What should be checked if an HMI command appears on screen but the machine does not respond?
Check the HMI tag mapping, communication status, PLC command logic, machine interlocks, and the current operating mode. The panel may successfully send a request while the PLC intentionally prevents the action because the required operating conditions have not been met.
