Technical Specifications

Function and Working Principle

The Siemens 6AG1124-0XC02-4AX1 functions as a graphical operator interface within an industrial automation system.

A typical operating structure is:

PLC / Controller → Industrial Network → HMI → Touchscreen → Operator Command → PLC / Machine

The panel can display information generated by the control system and provide authorized commands back to the machine.

Typical functions include:

• Machine status visualization
• Process monitoring
• Alarm display
• Parameter input
• Operator control
• Trend visualization
• Diagnostic information
• Production data display

The large display area is particularly useful when operators need to view several process parameters, machine states, alarms, and control buttons simultaneously.

22-Inch-Class Widescreen Display

The TP2200 platform provides a large widescreen TFT interface suitable for complex industrial visualization applications.

The display provides space for:

• Process diagrams
• Machine layouts
• Alarm lists
• Trend curves
• Numerical values
• Control buttons
• Diagnostic screens

The large screen can reduce the need to switch repeatedly between different HMI pages and can make complex machine information easier to organize.

Touchscreen Operation

The panel provides direct touchscreen operation for interaction with the HMI application.

Operators can use the interface to:

• Start or stop authorized machine functions
• Enter process parameters
• Navigate between operating screens
• Acknowledge alarms
• View diagnostic information
• Monitor equipment status
• Access maintenance pages

Touchscreen operation also allows machine builders to create application-specific control layouts without relying entirely on physical switches and buttons.

Communication Functions

The 6AG1124-0XC02-4AX1 supports PROFINET as well as MPI/PROFIBUS DP communication.

This allows the HMI to be integrated into automation architectures containing:

• Siemens PLCs
• Distributed I/O
• Variable speed drives
• Industrial networks
• Machine controllers
• Process equipment

Communication between the HMI and controller allows real-time process values and system status information to be presented to the operator.

SIPLUS Industrial Design

The 6AG1124-0XC02-4AX1 belongs to the SIPLUS Comfort Panels Standard family and uses a conformal-coated configuration.

The coating provides additional protection for the electronic assembly in appropriate industrial environments.

This makes the panel suitable for applications where environmental conditions require additional electronic protection compared with a conventional indoor office display.

The specified operating temperature range for this model is 0 to +45 °C.

A typical architecture may include:

Installation Guide

Step 1: Verify the Model

Before installation, confirm:

• Model number: 6AG1124-0XC02-4AX1
• HMI application compatibility
• PLC communication requirements
• Power supply requirements
• Available mounting space

The exact part number should always be checked before replacement.

Step 2: Prepare the Control Panel

Prepare the cabinet or operator station for the large-format HMI.

Check:

• Mounting opening
• Mechanical support
• Cable clearance
• Ventilation
• Operator viewing angle

Because the unit weighs 9.280 kg, the mounting structure should provide adequate mechanical support.

Step 3: Mount the HMI

Position the panel carefully in the prepared mounting opening.

Then:

1. Insert the panel into the opening.
2. Install the mounting hardware.
3. Secure the panel evenly.
4. Check that the display is properly aligned.

Avoid excessive mechanical pressure on the display or housing.

Step 4: Connect Power

Connect the required DC power supply.

Before energizing the unit:

• Verify polarity.
• Check wiring.
• Inspect the connector.
• Confirm stable power.
• Verify grounding requirements.

Step 5: Connect Communication

Connect the appropriate industrial communication interface according to the automation architecture.

Possible connections include:

• PROFINET
• MPI
• PROFIBUS DP

Check connector seating and communication configuration before commissioning.

Step 6: Configure the HMI

After startup:

• Load the required HMI project.
• Configure PLC communication.
• Verify screen navigation.
• Check process values.
• Verify alarm functions.
• Test operator input.

Step 7: Commission the System

Perform a complete functional test.

Check:

• Touchscreen response
• PLC communication
• Alarm display
• Process visualization
• Parameter entry
• Machine control
• Network communication

The HMI should be placed into normal production service only after successful testing.

Common Failure Symptoms

Troubleshooting Guide

HMI Does Not Start

Check the following:

1. Power supply.
2. Power wiring.
3. Connector seating.
4. Cabinet power status.
5. Grounding.

If the HMI remains inactive after the power system has been verified, further hardware diagnosis may be necessary.

PLC Communication Failure

If the HMI starts but does not show controller information:

• Check communication cables.
• Check network connections.
• Verify PLC status.
• Check HMI communication settings.
• Verify network configuration.
• Inspect connectors.

A communication failure does not necessarily indicate an HMI hardware fault; configuration and network problems should be checked first.

Touchscreen Failure

If the display works but touch commands are not recognized:

• Clean the screen.
• Check for physical damage.
• Restart the HMI.
• Check the project configuration.
• Test different areas of the touchscreen.

If the entire touchscreen remains unresponsive, hardware inspection may be required.

Display Problems

For flickering, abnormal images, or missing display areas:

• Check power stability.
• Inspect connections.
• Check cabinet temperature.
• Inspect the display for physical damage.
• Verify that the problem is not caused by the HMI application.

Persistent hardware-related display problems may require panel replacement.

Maintenance Recommendations

For reliable long-term operation:

• Keep the touchscreen clean.
• Prevent excessive dust accumulation.
• Maintain appropriate cabinet temperature.
• Inspect communication connections periodically.
• Check mounting hardware.
• Monitor recurring HMI alarms.
• Maintain backups of HMI project files.
• Keep controller and HMI configuration documentation available.

Avoid using sharp tools or excessive force on the touchscreen surface.

Replacement and Legacy System Considerations

The 6AG1124-0XC02-4AX1 is particularly relevant to maintenance and replacement projects involving existing SIPLUS HMI installations.

When replacing an existing unit, verify:

• Exact MLFB number
• HMI project compatibility
• PLC communication configuration
• Network architecture
• Power requirements
• Mounting arrangement
• Existing operating environment

For legacy equipment, keeping a tested replacement panel available can help reduce production downtime when an installed HMI develops a hardware fault.
