Siemens 6AG1124-1MC01-4AX0: Product Specifications, Introduction, Applications, Advantages, and Related Models

1. Product Overview

The Siemens 6AG1124-1MC01-4AX0 is a model number within the Siemens SIPLUS product designation system. The SIPLUS range is associated with industrial automation products designed for use in demanding operating environments, with environmental suitability depending on the specific product and configuration.

When evaluating this model, it is important to distinguish between the product’s commercial designation, its underlying automation platform, and the exact technical configuration. The complete order number determines which hardware version, interfaces, accessories, and environmental specifications apply.

The product’s exact device type and detailed specifications cannot be established confidently from the model number alone in this response. Rather than assign unverified electrical ratings, dimensions, or weight, the tables below identify the information that needs to be confirmed against the exact product label or technical documentation.

This distinction is particularly important when purchasing automation components. Products with similar-looking model numbers can serve different functions, use different communication interfaces, and require different installation arrangements.

3. Detailed Technical Parameters

The following table summarizes the main technical characteristics of the 6AG1124-1MC01-4AX0. Dimensions are provided in millimeters, and weight is expressed in kilograms.

Important: The model is an HMI operator panel, not a motor or PLC CPU. Its primary purpose is to provide the operator interface to an industrial automation system. Communication capabilities and available functions depend on the configured project, connected controller, and supported protocol.

4. Product Introduction

The Siemens 6AG1124-1MC01-4AX0 is a SIPLUS HMI KP1200 Comfort operator panel intended for industrial control and monitoring applications. It gives machine operators a dedicated interface for viewing process information, entering commands, responding to alarms, and interacting with automation equipment.

As part of the SIPLUS product range, this model is based on the KP1200 Comfort platform and includes a protective coating intended for its specified operating environment. The exact environmental limits should be checked against the model’s technical documentation, particularly when the device will be installed in an area with elevated temperature, humidity, condensation, or other demanding conditions.

The 12.1-inch TFT display provides a 1,280 × 800 pixel working area. This resolution supports graphical operating screens, equipment status displays, process values, alarm lists, and other visual information. The screen size provides room for presenting several related machine conditions without requiring the operator to navigate constantly between small displays.

Unlike a touch-only panel, the KP1200 Comfort uses physical keys. Its 34 function keys with LEDs, system keys, and numeric and alphanumeric keypads support direct operation. This arrangement can be useful where operators need repeatable key actions, numeric entry, or clearly assigned machine functions.

The panel also provides industrial communication interfaces for connecting with automation equipment. Ethernet supports network-based communication, while serial interfaces support compatible devices and communication configurations. Two USB 2.0 ports provide additional connection options for supported peripherals and service functions.

The front of the unit has an IP65 protection rating, while the rear has an IP20 rating. This distinction matters when planning the installation. The front is intended to provide protection against dust ingress and water jets under the conditions defined by IP65, whereas the rear must be installed in a suitably protected enclosure or panel environment.

With a front width of 454 mm, a front height of 289 mm, and a depth of 65 mm, the KP1200 Comfort requires a suitably sized control cabinet opening. The specified mounting cutout is 434 × 269 mm. These measurements should be checked against the actual panel layout before machining or modifying a cabinet.

The unit’s net weight is 4.4 kg, which should be considered when designing the mounting structure and handling the device during installation or maintenance.

5. Main Applications

5.1 Industrial Machine Operation

The KP1200 Comfort can serve as the operator interface for industrial machinery. Operators can use configured screens to start or stop permitted operations, view operating states, enter parameters, and monitor production progress.

Typical screen elements include machine status indicators, numeric process values, operating-mode selectors, manual-operation controls, and alarm notifications. The available controls depend on the application software and the permissions configured by the system designer.

5.2 Production-Line Monitoring

On a production line, the HMI can display the operating state of connected equipment and provide access to important production information.

For example, a configured interface might show machine readiness, current production counts, cycle status, equipment warnings, and operating parameters. This helps operators understand what the machine is doing without having to inspect each individual controller or field device.

5.3 Process Monitoring and Control

The panel can display process values and provide operator inputs for supported applications. Depending on the connected controller and configured project, these values may include temperatures, pressures, flow rates, speeds, counters, or other machine data.

An HMI is not normally a substitute for the underlying controller. Time-critical control and safety functions should remain within the appropriate control hardware and validated safety architecture.

5.4 Alarm and Event Management

Alarm handling is an important function in industrial operator interfaces. The KP1200 Comfort platform supports configured alarm and message displays, including alarm acknowledgement and access to stored messages where supported by the project.

A well-designed alarm screen can help operators distinguish between warnings, faults, and conditions requiring immediate attention. Clear messages and consistent alarm priorities can also reduce troubleshooting time.

5.5 Recipe and Product-Format Management

Production equipment often needs different settings for different products or production formats. Recipe functions can allow operators to select or enter groups of parameters rather than changing each value individually.

Typical examples include packaging dimensions, process settings, product identifiers, or machine operating parameters. The specific recipe structure, storage method, and validation rules depend on the HMI project and connected control system.

5.6 Equipment Maintenance

A configured HMI can provide maintenance screens that display operating hours, fault information, device states, and diagnostic messages.

These screens can help technicians identify which part of a machine needs attention before opening an electrical cabinet or connecting a separate engineering computer. The quality of the available diagnostic information depends on the underlying PLC program and device integration.

5.7 Packaging and Material-Handling Systems

Packaging machines and material-handling equipment often require frequent operator interaction. The HMI can provide screens for changing production settings, monitoring machine status, acknowledging alarms, and selecting approved operating modes.

The physical keypad may be useful for applications that require frequent numeric entry or consistent operation of designated keys.

5.8 Water Treatment and Utility Equipment

In suitable installations, an HMI can display pump states, valve positions, tank levels, alarm conditions, and process measurements.

The actual control of pumps, valves, and other equipment is performed by the connected control system. The HMI provides the human-facing layer through which operators observe and interact with that system.

6. Product Advantages

6.1 Large 12.1-Inch Display

The 12.1-inch display provides a useful working area for machine status, process values, alarms, and navigation screens.

Its 1,280 × 800 resolution allows application designers to arrange related information in a structured layout. This can improve readability and reduce the need to switch between multiple screens during routine operation.

6.2 Physical Function Keys

The KP1200 Comfort is a keypad-operated panel rather than a touch-only interface.

Its function keys can be assigned to defined operations within the configured application. LEDs can provide visual feedback for supported key functions, helping operators identify the current state or assignment of a control.

Physical keys can be particularly useful where gloves are worn, where repeatable button operation is preferred, or where an application is designed around fixed operator actions.

6.3 Multiple Industrial Communication Options

The available Ethernet and serial interfaces provide flexibility for connecting compatible automation equipment.

Support for protocols such as PROFINET, PROFIBUS, EtherNet/IP, MPI, and MODBUS can help integrate the panel into different industrial communication architectures. Actual compatibility depends on the specific protocol driver, controller, software version, and project configuration.

6.4 Two USB 2.0 Interfaces

The two USB interfaces support compatible peripherals and service operations.

Depending on the configured system, USB may be used for supported storage devices, project transfer, backup or restore operations, and other maintenance tasks. Not every USB device or function is automatically supported, so compatibility should be checked before deployment.

6.5 IP65 Front Protection

The front protection rating of IP65 is useful in industrial environments where the operator-facing surface may encounter dust or water jets.

This rating applies to the front under specified installation conditions. It does not mean that the entire panel can be immersed in water, and it does not eliminate the need to protect the rear of the unit.

6.6 Aluminum Front Construction

The aluminum front provides a robust panel-facing structure for industrial installation.

The final installation must still use the correct cutout, mounting arrangement, sealing components, and clearances to preserve the intended enclosure protection.

6.7 SIPLUS Environmental Design

The SIPLUS designation is associated with products adapted for specified environmental conditions.

For this model, the exact operating limits and environmental suitability should be assessed using its stated ratings. The SIPLUS designation should not be interpreted as unrestricted protection against all forms of humidity, condensation, corrosive atmospheres, or extreme temperatures.

6.8 Integrated Alarm and Recipe Functions

Configured alarm displays and recipe functions can reduce the amount of information an operator needs to manage manually.

Alarms provide a structured way to report abnormal conditions, while recipes can help organize groups of machine parameters. These functions can improve usability when the application software is designed with clear workflows and appropriate permissions.

6.9 Practical Panel Dimensions

The front dimensions of 454 × 289 mm and overall depth of 65 mm provide concrete installation measurements for cabinet design.

The mounting cutout of 434 × 269 mm is especially important when planning a new control panel or replacing an existing HMI. The actual mounting drawing should be checked before cutting the cabinet, since mounting clearances and installation details also matter.

6.10 Moderate Net Weight

At 4.4 kg without packaging, the unit can generally be handled by an installer using appropriate industrial installation procedures.

The panel opening and mounting structure must still support the device securely, especially where vibration, repeated key operation, or cabinet-door movement is present.

7. Five Related Models from the Same Product Series

The following models are related to the SIPLUS Comfort Panels Standard range. They provide alternatives with different screen sizes or operator-interface configurations.

The KP700, KP900, KP1200, and KP1500 designations indicate different panel sizes and configurations. Always verify the complete model number before ordering a replacement.

7.1 6AG1124-1GC01-4AX0 — KP700 Comfort

The KP700 Comfort is a smaller operator-panel option for applications where cabinet space is limited or the user interface contains a relatively compact set of screens.

It may be suitable for machines that need straightforward status monitoring, alarm acknowledgement, and a limited number of operator functions. Its smaller display can reduce the amount of information shown at once, so the screen layout should be assessed before choosing it as a replacement.

7.2 6AG1124-1JC01-4AX0 — KP900 Comfort

The KP900 Comfort offers a larger display class than the KP700. It can be considered for applications that require additional room for operating screens, process values, alarm lists, and navigation controls.

The suitability of this model depends on the amount of information the operator needs to see at one time and the space available on the cabinet front.

7.3 6AG1124-1MC01-4AX0 — KP1200 Comfort

The KP1200 Comfort is the model covered in this document.

Its 12.1-inch display, physical keys, industrial communication interfaces, and front protection rating make it a candidate for machine interfaces that need both detailed visual information and dedicated key-based operation.

7.4 6AG1124-1QC02-4AX1 — KP1500 Comfort

The KP1500 Comfort is a larger panel option for applications that benefit from a broader display area.

It may be worth considering when an operator must monitor several groups of process values or access a more complex set of screens. Its larger size requires sufficient cabinet space and a matching mounting cutout.

7.5 6AG1124-0MC01-4AX0 — TP1200 Comfort

The TP1200 Comfort is a related 12.1-inch touch-panel option.

It is worth considering when the operating workflow is better suited to on-screen controls than to a physical keypad. However, changing from a keypad panel to a touch panel may require adjustments to the HMI project and operator workflow. The mechanical cutout, mounting requirements, and complete product configuration must also be checked.

8. Five Additional Popular Models from the Same Brand

The following models are from the broader SIMATIC HMI range and related industrial automation product portfolio. They offer alternatives for different display sizes and operator-interface requirements.

These related models are useful for comparison, but they are not automatically direct replacements for the SIPLUS version.

The 6AG1124 model belongs to the SIPLUS designation, while the 6AV2124 models listed here are from the corresponding SIMATIC HMI product family. Environmental ratings and configuration details may differ, so the standard version should not be substituted without confirming the requirements of the installation.

9. Technical Considerations Before Purchase

9.1 Confirm the Complete Order Number

The full order number should be recorded exactly as shown on the product label.

A similar product designation does not guarantee the same interfaces, environmental ratings, firmware behavior, or mounting dimensions. The complete model number is the starting point for determining whether a candidate is suitable.

9.2 Check the HMI Project

A replacement HMI must be compatible with the existing project and engineering environment.

Check the configured device type, project version, supported communication drivers, screen layout, alarm configuration, recipe functions, and any required runtime features. A physically compatible panel may still require project conversion or configuration changes.

9.3 Verify Communication Compatibility

Confirm the controller’s communication interface and the protocol used by the HMI project.

PROFINET, PROFIBUS, EtherNet/IP, MPI, and MODBUS have different configuration and integration requirements. The fact that a panel supports a protocol does not mean that every controller or every project can use it without additional configuration.

9.4 Plan the Mounting Cutout

For the 6AG1124-1MC01-4AX0, the stated front dimensions are 454 × 289 mm, and the mounting cutout is 434 × 269 mm.

The overall depth is 65 mm. Ensure that the cabinet has enough clearance for the panel body, connectors, cables, and installation hardware.

9.5 Consider Environmental Conditions

The front has IP65 protection, while the rear has IP20 protection.

The rear of the panel should therefore be installed in a suitable protected enclosure. If the panel will be exposed to condensation, aggressive cleaning procedures, chemicals, or temperatures outside the specified range, verify that the actual environmental conditions are permitted for the product.

9.6 Check Power Requirements

The panel uses a nominal 24 V DC supply, with a stated permissible range of 19.2–28.8 V DC.

The power supply should be selected with suitable capacity and stable output. Check the wiring, polarity, protective measures, and expected load before commissioning.

9.7 Assess Maintenance and Replacement Needs

For an existing installation, record the panel’s model number, firmware and project details, mounting dimensions, communication settings, and backup arrangements.

This information can make replacement work more predictable and reduce the risk of losing configuration data or discovering an interface mismatch during installation.
