Why Monitoring Makes a Difference in Industrial Facilities

In practice, it is not just the technology that matters, but also having a constant overview of system conditions, consumption, and deviations. Effective monitoring provides a clear definition of “what is normal”: temperatures, pressures, operating times, load profiles, and setpoints. As soon as data falls outside these parameters, monitoring allows causes to be identified more quickly and issues to be addressed specifically—before they lead to malfunctions, downtime, or unnecessary energy costs.

This is crucial for companies because:

  • Decisions are made based on data.
  • Security and operational continuity increase when deviations are detected early.
  • Optimizations become verifiable, allowing you to measure, manage, and sustain efficiency gains.

That’s why you should choose ONI

Everything under one roof

How your monitoring works with ONI

ONI links plant operations and service via a globally oriented data and information network—this means that, in principle, any ONI plant can be contacted.
Once you have given your approval, you can also access the system via the data network to read and evaluate status reports, adjust setpoints, and detect deviations in a timely manner.

The result: Monitoring becomes the foundation for stable availability and energy-efficient operation—in line with ONI’s commitment to sustainably reducing energy costs.

Types of Monitoring

Overview of Monitoring Solutions
 

System Monitoring

For continuous operational transparency with operating statuses, messages, and trends—as the basis for stable availability and quick decisions.
Typical functions:

  • Visualization of operating statuses and messages (e.g., warnings/alarms)
  • Trend graphs for root cause analysis (when did the deviation begin?)
  • Clear overview of critical parameters so that malfunctions are not “overlooked”

Energy Monitoring

When potential savings need to be identified and optimizations implemented in a measurable way—in line with ONI’s focus on “sustainably reducing energy costs.”
Typical features:

  • Transparency of consumption and load profiles as a basis for decision-making
  • Identification of efficiency potential (e.g., unnecessary base load, incorrect setpoints)
  • Proof of effectiveness: Optimization can be substantiated with data

Remote Monitoring & Continuous Monitoring (upon approval)

Secure access via a data network to read/evaluate status reports and detect deviations in a timely manner.
This offers particular advantages for distributed locations: ONI explains that networked data technology enables constant monitoring and flexible access to systems distributed worldwide.

Monitoring as Part of Maintenance & Service

Monitoring complements maintenance: The goal is trouble-free, energy-efficient operation—with service in the background. ONI emphasizes comprehensive service and the ability to monitor systems via the data network; regular maintenance remains a fundamental prerequisite for trouble-free, energy-saving operation.

Typical applications for monitoring

  • Early detection of deviations: Parameters drift (e.g., temperature, pressure, flow)—monitoring alerts you before the situation becomes critical.
  • Preventing malfunctions and downtime: Small deviations often lead to malfunctions that incur costs. Networked monitoring helps you respond early.
  • Energy efficiency in day-to-day operations: Understand load profiles, reduce base load, optimize setpoints—and accurately measure the impact.
  • Operational reporting for users & teams: A unified overview for operators, maintenance, and management (who sees what, when?).
  • Cross-site management: Consistent standards, comparable metrics, better control across multiple systems/applications.
  • Service-based optimization: Evaluate status reports after approval, adjust setpoints, and detect deviations early.

Questions & Answers

FAQ on Monitoring

Monitoring involves the continuous surveillance, observation, and control of system statuses and data. At ONI, it is primarily used to stabilize system availability and systematically improve energy efficiency—with the goal of sustainably reducing energy costs.

Common synonyms include monitoring, observation, control, or “ongoing oversight.” In practice, it always refers to collecting and analyzing data and using it to determine appropriate actions.

Depending on the solution: operating states, messages/alarms, trend data, consumption figures, and load profiles. The goal is to turn these key metrics into a solid basis for decision-making.


Once you have granted authorization, ONI can connect to the system via the data network, read and evaluate status reports, and detect anomalies in a timely manner. In this context, security means clearly defined authorization procedures, defined user roles, and traceable interventions.

Not quite. Application Performance Monitoring (APM), or performance monitoring, typically refers to IT applications and their functionality and response times. Plant and energy monitoring, on the other hand, focuses on the operation, energy consumption, and process parameters of technical systems. In modern environments, these two perspectives complement each other—especially when data is consolidated in a (private) cloud.

Whether in the cloud or on-premises: What matters most is that data is reliably available and that responsibilities are clearly defined (management, access, roles). The licensing and operating models depend on the specific solution or implementation.
