The Siemens 6AV2124-0GC01-0AX0 is a SIMATIC HMI TP700 Comfort Panel used for operator control and machine visualization in industrial automation systems. It combines a 7-inch widescreen TFT display with touch operation, allowing operators to monitor process variables, access equipment controls, review alarms, and interact with PLC-based machinery from a local interface.
Unlike entry-level operator panels, the TP700 Comfort belongs to Siemens’ Comfort Panel family, which supports more extensive visualization and communication requirements. Its 16-million-color display allows machine builders to organize process graphics, operating indicators, alarm information, and parameter-entry screens into a clear interface suited to production environments.
The panel supports PROFINET and MPI/PROFIBUS DP communication, making it suitable for automation architectures that use Ethernet-based connections or compatible PROFIBUS networks. Its 12 MB configuration memory provides storage for the HMI project, while Windows CE 6.0 forms part of the panel’s operating platform. Configuration is supported from WinCC Comfort V11.
In a production machine, the TP700 Comfort can display operating modes, production counts, motor states, temperature readings, and fault messages. An operator can select a machine section, adjust permitted parameters, or acknowledge an alarm through the touchscreen. The PLC remains responsible for executing the actual machine logic and determining whether requested operations are permitted.
The availability of both PROFINET and MPI/PROFIBUS DP interfaces is particularly useful when integrating the panel into established Siemens automation installations. It allows the communication architecture to be selected according to the controller, network design, and requirements of the machine project.
The 6AV2124-0GC01-0AX0 is therefore suited to applications requiring a dedicated local interface with graphical visualization, touch-based operation, and integration into a compatible Siemens control system. Correct engineering of communication links, HMI tags, alarm definitions, and operator permissions is essential to ensure that the displayed information corresponds to the actual machine state.

The 6AV2124-0GC01-0AX0 functions as the operator visualization layer of a PLC-based automation system. It exchanges data with the connected controller, displays information defined in the HMI project, and sends configured operator actions to the control system.
Operator Input → TP700 Comfort Panel → PROFINET or MPI/PROFIBUS DP → PLC → Machine Equipment
During engineering, the machine builder creates an HMI project containing screens, process indicators, navigation controls, input fields, and alarm displays. Each object is associated with the appropriate controller variable or HMI function. The completed project is transferred to the panel using the supported engineering and connection method.
During operation, the panel reads the configured process data and updates the corresponding screen elements. For example, a pump-control screen may show the pump’s running state, discharge pressure, operating mode, and active alarms. The information displayed depends on the values supplied by the controller and the configuration of the HMI tags.
When an operator touches a configured button, the panel performs the associated action. This may involve writing a command request, changing a permitted setpoint, selecting another screen, or acknowledging an alarm. The PLC evaluates machine conditions and interlocks before carrying out any operation that affects the equipment.
The alarm system provides another important part of the operating process. When the controller or HMI detects a configured fault condition, the panel can display the associated message and allow the operator to access relevant diagnostic information. Proper alarm configuration helps distinguish operating warnings from conditions requiring immediate attention.
Communication reliability depends on correct device addressing, network configuration, controller compatibility, and tag mapping. During commissioning, engineers should test both the displayed values and the commands sent from the panel. This verifies that the HMI is not merely connected but is exchanging the intended information with the automation system.
The TP700 Comfort occupies the operator-interface layer between personnel and the machine control system. It presents information from the PLC and provides the interface through which permitted operator actions are communicated to the controller.

The HMI does not replace the PLC’s control responsibilities. The controller executes the machine program, while the TP700 Comfort provides visualization and operator interaction. Safety-related functions must remain within the appropriately engineered safety system rather than relying solely on ordinary HMI commands.

The TP700 Comfort belongs to the Comfort Panel family and supports a different range of visualization and communication capabilities from Basic Panels. This model includes both PROFINET and MPI/PROFIBUS DP interfaces, making it suitable for compatible automation architectures using either connection type.
The choice depends on the PLC, network architecture, and available communication interfaces. PROFINET is suitable for compatible Ethernet-based installations, while MPI/PROFIBUS DP supports compatible legacy and established Siemens networks. The HMI project must be configured for the selected connection.
The configuration memory is available for the panel’s HMI project and associated configuration data. The project must remain within the device’s supported resource limits, including memory, screen objects, tags, and configured functions.
Check the controller’s source variable, HMI tag mapping, data type, scaling, and communication status. If the PLC value is correct but the displayed value is not, investigate the HMI configuration and any conversion or scaling applied to the screen object.
