Process visualization systems – find manufacturers and suppliers

Process visualizations are systems or software solutions that graphically display industrial processes, systems or machines and help to monitor them.

They enable operators to identify the current status of a system, issue control commands, monitor alarms and collect data for optimization. Process visualizations are a central component of modern automation systems, as they increase transparency, safety and efficiency.

Below you will find the functionality, types and use of process visualizations as well as a brief overview of their benefits:

How process visualizations work:

The main task of a process visualization is to capture data from the system or process, process it and present it to the operator in an understandable way. The functionality can be described in several steps:

1. Data acquisition:
   Sensors, actuators, controllers (PLC, DCS) or other automation components continuously supply process data.
2. Data preparation:
   Raw data is converted into an understandable form, e.g. converted into physical units, compared with target values or historicized.
3. Visualization:
   Graphical interfaces show process information in the form of diagrams, graphics, system layouts, trends or animations.
   Colors, symbols and alarms help to identify deviations immediately.
4. Interaction:
   Operators can use the HMI to issue control commands, change setpoints or switch certain process areas on and off.
5. Alarm and event management:
   Critical conditions are highlighted immediately, alarm histories are logged and priorities are defined if necessary.
6. Data logging and analysis:
   Historical process data is stored and used for analysis, optimization, maintenance planning or quality control.

Types of process visualizations:

Process visualizations can be differentiated according to various criteria:

By system structure:

1. PLC-based visualization:
   Direct connection to programmable logic controllers, often as operating panels or touchscreens.
2. SCADA systems (Supervisory Control and Data Acquisition):
   Centralized monitoring and control of large or distributed systems. Offer advanced functions such as remote access, alarm management and history analysis.
3. DCS (Distributed Control System):
   Integrated in complex processes (e.g. chemical, energy plants), with decentralized control and redundant process visualization.

By user interface:

1. Graphical HMI panels:
   Local user interfaces directly on machines or production lines, often touchscreen-based.
2. PC-based HMI:
   Software on industrial PCs, enables extensive visualization and analysis.
3. Web-based interfaces:
   Access via browser or mobile devices, supports remote monitoring and integration into IoT systems.

According to functionality:

1. Simple status displays:
   Show basic operating statuses, on/off switches, sensor statuses.
2. Interactive process graphics:
   Animated representations of flow processes, valves, pumps, motors or conveyor belts.
3. Trend and analysis functions:
   Real-time trends, historical data, key performance indicators, alarm statistics.
4. Fault diagnosis and predictive maintenance:
   Analysis of conditions for early detection of faults.

Areas of application for process visualizations:

Process visualizations are used in almost all industries:

1. industrial automation:
Production lines, packaging systems, conveyor belts, machine control systems.

2. Energy and supply systems:
Power grids, power plants, water and wastewater plants, oil and gas production.

3. Chemicals and pharmaceuticals:

Advantages of process visualization:

• Transparency: operating states, process values and faults are immediately visible, enabling quick decisions to be made.
• Increased efficiency: Optimization of production processes, reduction of downtimes and improved use of resources.
• Increased safety: Early detection of critical conditions, alarms, protective mechanisms and remote monitoring increase the safety of systems and operating personnel.
• Fault diagnosis: Analysis of trends and historical data facilitates root cause analysis and maintenance planning.
• Flexibility and adaptability: Modern systems make it easy to adapt the visualization to changing processes or new machines.
• Integration and automation: SCADA or web-based systems enable integration into higher-level production control systems and IoT solutions.
• Documentation and compliance: Historical data and alarm logbooks support quality control, certifications and legal requirements.

Process visualizations are a central element of modern automation, as they enable complex industrial processes to be displayed, controlled and optimized in an understandable way. They not only offer transparency and safety, but also increase efficiency, reduce downtimes and support preventive maintenance. The choice of the right system depends on the size of the plant, the complexity of the processes, the safety requirements and the integration options. Professionally implemented, process visualizations form the basis for efficient, safe and sustainable production and operating processes.

Here you will find the most important aspects to consider when purchasing process visualizations:

Purchasing process visualizations is much more than just buying software or a panel. Process visualizations form the central interface between operating personnel and industrial processes, systems or machines. Incorrect selection can lead to production interruptions, operating errors or inadequate data acquisition. A professional purchasing process takes into account technical requirements, quality, integration, delivery capability and compliance in order to ensure reliable, efficient and secure solutions in the long term.

• The first step is to clarify whether a SCADA system, DCS-HMI, PC-based visualization, web or touchscreen solution is required.
• The visualization must be able to record and display all relevant process data, e.g. sensor values, actuator states, alarms, setpoints and trends.
• Compatibility with controllers, sensors and actuators is crucial. Supported protocols such as OPC, Modbus, ProfiNet, EtherCAT and CAN must be compatible with the existing infrastructure.
• Animations, real-time trends, alarm lists, interactive operation, drill-down functions and dashboards should meet the requirements of the system.
• The system must be able to easily map future expansions or additional process areas.
• Real-time capability, speed of response to alarms and data updating are crucial, especially for safety-critical or fast-moving processes.
• Preference is given to providers with stable development, a long market presence, regular updates and certified quality (ISO 9001).
• The visualization must also run stably under load, in the event of network interruptions or system updates. Redundancy options may be required.
• Access controls, user rights management, audit trails, alarm prioritization and protection against unauthorized changes are essential.
• Complete manuals, training, software support, remote maintenance options and access to updates are crucial for professional operation.
• It should be possible to adapt to specific process requirements, integrate additional modules or interfaces without the need for a completely new development.
• The manufacturer or supplier must offer timely delivery and support for installation and commissioning.
• check compatibility with existing PLC, DCS or SCADA systems, network infrastructure, history servers and reporting systems.
• Flexible license models, e.g. depending on the number of clients, computers or process points, and clear contract terms are important.
• Regular software updates, patches and long-term support ensure stable operation over the entire life cycle.
• RoHS, REACH, CE marking, industry-specific automation standards such as IEC 61508, ISO 13849 must be fulfilled.
• HMI/SCADA solutions should support security functions, e.g. user rights, alarm management, in order to comply with legal regulations and industry requirements.
• Data security must be guaranteed, especially for networked systems. Encryption, network segmentation and backup functions are important criteria.
• In addition to the purchase price, implementation, training, maintenance, extensions and integration should also be taken into account.
• Inadequate visualization can cause production downtimes, operating errors or data loss, which significantly increases the overall costs.
• Scalable systems and long-lasting software platforms secure the investment value for years to come.

The purchase of process visualizations requires a holistic view of technology, quality, integration, security and costs. Only if these aspects are carefully examined and tailored to the specific process requirements can a visualization system be selected that is reliable, efficient, expandable and secure. The right choice not only ensures the operational capability and transparency of systems, but also enables the long-term optimization of processes, maintenance and resources.
