4. Product Introduction

4.1 Designed for detailed industrial visualization

The TP1500 Comfort is intended to provide operators with a clear, centralized interface for interacting with industrial machinery and automated processes.

On a large production machine, operators may need to see the overall operating state, several measured values, equipment status, alarm messages, and control buttons. A 15.4-inch display provides more room for these elements than a compact HMI.

The application designer can arrange the interface into different pages, such as a machine overview, production screen, setup page, alarm list, recipe page, and maintenance menu. This allows the operator to move between tasks without relying on a large number of separate physical indicators and switches.

The actual functions available depend on the HMI project and the connected controller. The panel provides the interface, while the PLC or other control system carries out the underlying automation logic.

4.2 High-resolution widescreen display

The 1280 × 800-pixel resolution gives the TP1500 Comfort room for detailed graphics and organized information layouts.

The display can be used for equipment diagrams, process values, trend displays, status indicators, and alarm information. Its support for 16.7 million colors allows the designer to distinguish operating states and present visual information consistently.

For example, a production overview can show the status of several machine sections, while a separate diagnostic page can display detailed values for a selected section.

The larger display is most useful when the interface is designed carefully. Clear labels, consistent navigation, readable text, and sensible grouping of controls are more important than filling every available area with information.

4.3 Conformal-coated construction

The SIPLUS version includes conformal coating intended to improve the resistance of relevant electronic components to specified environmental stresses.

This feature can be useful in industrial installations where humidity, condensation, or certain corrosive atmospheric conditions are concerns. It adds an environmental-protection characteristic to the underlying Comfort Panel platform.

The coating does not make the entire panel suitable for unrestricted exposure to liquids or chemicals. The specified operating range remains 0°C to +50°C, and the installation must still account for enclosure protection, condensation, ventilation, and cleaning practices.

4.4 Industrial communication

The TP1500 Comfort provides PROFINET and MPI/PROFIBUS DP interfaces for integration into compatible automation systems.

PROFINET is suitable for Ethernet-based industrial communication, while MPI/PROFIBUS DP supports compatible automation architectures using those interfaces. The actual connection depends on the PLC model, network design, communication protocol, and project configuration.

This combination can be useful in installations where the control system has existing PROFIBUS equipment or where a suitable Ethernet-based architecture is used.

Before replacing another HMI, verify the required interface type, connector arrangement, project compatibility, and engineering software support. Two panels with the same display size are not necessarily direct substitutes.

4.5 Configuration and operating functions

The panel supports common HMI functions such as alarm handling, process-value display, process-value input, and recipe management.

These functions allow the project designer to create a user interface that reflects the actual machine workflow. For example, an operator may view a process value, enter an authorized setting, select a recipe, or acknowledge an alarm.

The available functions and their behavior depend on the configured project, the connected controller, and the engineering software used.

5. Product Applications

5.1 Automated manufacturing lines

The TP1500 Comfort is suitable for manufacturing equipment that needs a large, detailed operator interface.

Typical applications include automated assembly lines, material-handling systems, machining equipment, and production stations with several operating sections.

The screen can display overall machine status, production counts, operating modes, process values, and alarms. Maintenance pages can provide more detailed diagnostic information for individual equipment sections.

5.2 Packaging and filling machinery

Packaging and filling systems often involve several operating modes, product settings, counters, alarms, and changeover procedures.

A large HMI can group these functions into dedicated screens for production, setup, recipe selection, troubleshooting, and maintenance.

Operators can view production information and access permitted controls from a common interface. Recipe-related functions depend on how the HMI project and PLC are configured.

5.3 Process-control systems

The panel can be used in suitable process applications where operators need to monitor equipment states and measured values.

Examples include temperature, pressure, flow, level, and operating-status displays. A graphical overview can show the relationship between process sections, while detailed pages can focus on specific instruments or equipment.

The HMI displays data supplied by the control system. It does not replace the sensors, PLC, independent protective devices, or safety-related control functions.

5.4 Water treatment and utility equipment

In suitable installations, the TP1500 Comfort can serve as a local operator station for pumping systems, filtration equipment, water-treatment processes, and industrial utilities.

Operators may use it to review pump status, tank levels, flow values, active alarms, and maintenance information.

The large screen can help present an overview of the system while allowing navigation to detailed pages for individual pumps, valves, and process stages.

5.5 Food and beverage production

The TP1500 Comfort may be used on selected food-processing and beverage-production equipment where operators need to view production data, process values, and alarm messages.

Its conformal-coated construction may be relevant to specified environmental conditions. However, the panel should not automatically be considered suitable for direct washdown or exposure to every cleaning chemical.

The front protection rating, cabinet design, mounting seal, cleaning procedure, and applicable hygiene requirements must all be considered before installation.

5.6 Chemical and industrial utility equipment

The conformal-coated design can be useful in selected industrial environments where electronic components may be exposed to specified atmospheric stresses.

Potential applications include process skids and utility systems where humidity or certain corrosive atmospheres are concerns.

Actual suitability depends on the chemical exposure, concentration, duration, ambient conditions, and installation method. The panel must remain within its documented environmental limits.

5.7 Maintenance and diagnostic stations

The TP1500 Comfort can provide a dedicated maintenance interface for reviewing machine status, checking alarm histories, inspecting process values, and accessing authorized service functions.

A well-designed project can give technicians more useful information than a simple fault lamp, helping them identify which machine section needs attention.

The quality of this diagnostic experience depends on the application project and the diagnostic information provided by the control system.

6. Main Product Advantages

6.1 Large screen for complex applications

The 15.4-inch display gives operators space to view detailed process diagrams and multiple groups of information together.

This is particularly useful when a machine has several subsystems or when operators need to monitor production status, equipment states, and alarms at the same time.

6.2 High-resolution visualization

The 1280 × 800-pixel resolution supports detailed screen layouts and a wide range of graphical elements.

Designers can organize information into clearly defined areas, helping operators distinguish machine status, operating controls, and diagnostic information.

6.3 Conformal coating for specified environmental conditions

The conformal coating provides additional protection for relevant electronic components compared with an otherwise similar uncoated configuration.

It can be useful in installations where humidity, condensation, or certain corrosive atmospheric conditions are concerns. It does not remove the need for suitable enclosure protection or environmental assessment.

6.4 Flexible touchscreen operation

The touchscreen can be configured around the actual operating procedures of the machine.

Separate pages can be created for startup, production, setup, alarms, recipes, and maintenance. This can simplify the physical control panel and make the operator workflow more consistent.

6.5 Alarm management and diagnostics

Alarm handling allows the application to display active faults, maintain alarm information, and provide acknowledgment functions.

When alarms are written clearly and associated with the correct equipment, they can help operators and maintenance technicians identify problems more efficiently.

6.6 Recipe and process-value management

Recipe and process-value functions can support machines that run different products or require adjustable operating parameters.

The HMI can provide the interface for selecting or entering those values, while the control system applies them according to the machine’s configured logic.

6.7 Integration with existing automation systems

The combination of PROFINET and MPI/PROFIBUS DP interfaces provides options for integration into compatible automation architectures.

This may be useful for equipment upgrades where the existing control system uses PROFIBUS or where a suitable PROFINET network is already installed.

Compatibility should be verified at the protocol, hardware, and project levels before a replacement is selected.

6.8 IP65-rated front protection

The IP65 front rating helps protect the installed panel front against dust and water jets under the conditions defined by the rating, provided the panel is correctly mounted and sealed.

The rear has a different protection rating, so the complete installation must protect the rear side and electrical connections appropriately.

6.9 Suitable for centralized operator stations

The larger screen can make the TP1500 Comfort a useful choice for a machine’s main operator station.

It provides room for an overview screen and several detailed pages without requiring the operator to rely on multiple smaller displays.

7. Product Series and Model Positioning

The SIPLUS Comfort Panels Standard series includes multiple display sizes and hardware configurations for industrial operator control and monitoring.

The TP1500 Comfort is a large-format panel intended for applications that benefit from a detailed overview of the machine or process.

These models occupy different positions within the broader Comfort Panel range. A larger display is not always necessary, and the exact SIPLUS environmental specification must be checked independently of the screen size.

For a replacement project, verify the full order number, interface configuration, engineering software compatibility, operating-temperature range, mounting cutout, and installed weight.

9.5 SINAMICS G120C

The SINAMICS G120C is a variable-frequency drive used to control the speed of compatible electric motors.

In an automated machine, the PLC may manage the operating sequence while the drive controls motor operation. The HMI can display operating status and alarms when the application has been configured to provide this information.

The exact drive variant must be selected according to motor power, supply voltage, load requirements, and installation conditions.

10. Installation and Configuration Considerations

10.1 Mechanical installation

The TP1500 Comfort has front dimensions of 415 × 310 mm, a mounting cutout of 396 × 291 mm, and an overall depth of 75 mm.

Before modifying a cabinet, check the installation drawing for the exact device. Ensure there is enough room behind the panel for the connectors, cable bends, and maintenance access.

The mounting arrangement must also support the panel’s 4.4 kg net weight and maintain the required front seal.

10.2 Electrical power supply

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

The power supply should have adequate capacity for the HMI and any other connected equipment. Follow the appropriate wiring, grounding, and protection requirements for the installation.

10.3 Communication and controller compatibility

The TP1500 Comfort supports PROFINET and MPI/PROFIBUS DP interfaces. Confirm which interface the application requires and whether the connected controller supports the intended communication setup.

When replacing an existing panel, check whether the original HMI project can be reused. Differences in hardware generation, firmware, or configuration software may require project conversion or changes to communication settings.

10.4 Operating environment

The specified operating-temperature range is 0°C to +50°C. Do not assume that conformal coating automatically permits operation outside this range.

Consider the installation’s humidity, condensation risk, possible chemical exposure, cabinet temperature, and cleaning procedures. The IP65 rating applies to the panel front when correctly installed; the rear side requires appropriate protection.

10.5 HMI screen design

A well-designed operator interface should make the machine’s current state easy to understand.

The main page should present the most important status information, while separate pages can handle alarms, settings, recipes, and maintenance. Use clear labels and consistent button placement, and avoid relying on color alone to communicate important operating conditions.

Safety-critical functions should be handled by the appropriate safety-related control architecture rather than relying on the HMI alone.
