Application
Unexpected machine stoppages, recurring quality deviations, and intermittent process disturbances remain among the most challenging problems in industrial production. While modern automation systems generate vast amounts of operational data, maintenance and engineering teams often face a frustrating reality: when a problem occurs, the available information does not provide enough detail to explain why it happened.
Traditional troubleshooting methods typically rely on PLC diagnostics, SCADA trends, historian data, and operator observations. Although these tools provide valuable insight into plant operation, they are often limited by sampling rates and data granularity. As a result, critical events may occur between recorded samples and remain invisible during root cause investigations.
In many cases, the issue is not a lack of data, but a lack of sufficiently detailed data. High-resolution data acquisition addresses this challenge by providing a precise, time-synchronized view of machine and process behavior, enabling engineers to reconstruct events with a level of accuracy that is not possible with conventional monitoring systems.
Why Traditional Process Data Often Falls Short
Industrial historian and SCADA systems are primarily designed for production monitoring, reporting, and performance analysis. They excel at tracking long-term trends and key performance indicators, but they are typically not intended to capture fast, transient events that occur within milliseconds.
Many production problems originate from precisely these short-duration events. Typical examples include:
- A valve opens slightly later than expected.
- An interlock changes state for only a few milliseconds.
- A sensor experiences a brief disturbance.
- Multiple digital signals occur in the wrong sequence.
- A vibration spike triggers a downstream effect that is no longer visible in recorded data.
While each of these events may seem insignificant in isolation, they can ultimately result in quality defects, process instability, or unexpected machine downtime.
The challenge becomes even greater when multiple events interact. A fault condition may result not from a single cause, but from a specific sequence of signal changes occurring within a narrow time window. If the available data lacks sufficient resolution, engineers are forced to make assumptions about what happened rather than relying on objective evidence.
Consequently, troubleshooting efforts often become time-consuming exercises in eliminating possibilities rather than identifying demonstrable causes.
The Power of High-Resolution Data Acquisition
High-resolution data acquisition with the iba system provides a different approach by continuously recording signals at significantly higher sampling rates than conventional monitoring systems. Rather than analyzing broad trends, engineers gain the ability to observe the precise timing relationships between machine signals, sensor inputs, drive responses, and control actions. Events can be reconstructed in the exact order in which they occurred, allowing investigations to focus on facts rather than assumptions.
This level of visibility enables engineering teams to:
- Reconstruct events leading up to a fault.
- Measure precise timing relationships between signals.
- Detect sequencing problems in automated processes.
- Analyze cause-and-effect relationships with confidence.
- Quantify process variations that would otherwise remain hidden.
- Reduce troubleshooting time by focusing directly on the root cause.
By capturing process data with millisecond or even microsecond resolution, engineers can determine exactly what happened before, during, and after a disturbance. Instead of relying on repeated testing and trial-and-error methods, maintenance teams can use recorded data to identify the underlying source of a problem more quickly and accurately.
Enhancing Existing Automation Systems
A common misconception is that achieving this level of diagnostic capability requires a complete modernization of the automation infrastructure. In practice, many facilities can significantly improve process visibility without replacing existing control systems.
A dedicated data acquisition platform can operate alongside established PLC, SCADA, and historian environments, gaining additional information while preserving the existing automation architecture.
This approach allows organizations to expand their diagnostic capabilities incrementally. Engineering teams gain access to higher-resolution information without disrupting production or undertaking large-scale automation projects.
Platforms such as ibaPDA are designed specifically for this purpose. ibaPDA continuously acquires, synchronizes, and stores data from automation systems, drives, sensors, and industrial communication networks, providing a comprehensive view of machine and process behavior across an entire production environment.
Monitoring Industrial Communication Networks
Many modern production processes rely heavily on industrial Ethernet communication. As machine complexity increases, communication issues can become difficult to identify using traditional diagnostic methods.
Dedicated Profinet monitoring devices expand system visibility by capturing communication data directly from the network. This allows engineers to observe both process values and communication behavior without requiring extensive modifications to PLC programs.
The approach provides access to information that is often difficult to obtain through conventional diagnostics, including:
- Communication timing behavior.
- Network-related state changes.
- Intermittent communication disturbances.
- Signal interactions across multiple controllers.
- Communication sequences preceding a fault event.
Network-level monitoring can be particularly valuable when investigating intermittent disturbances that cannot easily be reproduced. By extending diagnostics beyond the PLC and into the communication infrastructure itself, engineers gain a more complete understanding of the systems they are troubleshooting.
High-Speed Acquisition Beyond Conventional Monitoring
Some industrial applications require significantly higher sampling rates than those typically available through standard automation systems. Mechanical events, vibration phenomena, energy disturbances, and sensor dynamics often occur too quickly to be captured through conventional data collection methods.
Dedicated acquisition hardware such as ibaPADU addresses these requirements by recording analog and digital signals at sampling rates of up to 150 kHz. Such high-frequency acquisition makes it possible to analyze signal behavior that would otherwise remain invisible.
This capability supports a wide range of diagnostic and analytical applications:
- Sensor diagnostics.
- Vibration monitoring.
- Mechanical condition monitoring.
- Energy analysis.
- Power quality investigations.
- Dynamic process analysis.
For short-duration events, even small increases in sampling frequency can reveal previously hidden patterns. High-speed acquisition provides the level of detail required to identify subtle process interactions that may ultimately lead to production losses, equipment damage, or quality defects.
In many investigations, the missing link is not expertise. It's visibility. High-resolution data provides the level of detail needed to uncover root causes that remain hidden in conventional trending systems.

The Importance of a Common Time Base
One of the greatest challenges in industrial troubleshooting is the fragmentation of information across multiple systems.
Process data may be stored in PLC historians, electrical measurements may originate from specialized monitoring equipment, vibration information may reside in dedicated condition monitoring systems, and quality records may exist in separate databases. Each source contains valuable information, but correlating events becomes difficult when timestamps differ or synchronization is lacking.
Typical disconnected data sources include:
- PLC trend data.
- Electrical measurements.
- Vibration monitoring systems.
- Quality databases.
- Operator observations.
- Production event logs.
The iba system addresses this issue by synchronizing information from diverse sources onto a common timeline. This enables engineers to compare events across multiple systems with high temporal accuracy.
To retain these synchronized datasets over extended periods, ibaHD-Server provides a scalable historian environment for long-term storage and centralized access to process data. This allows engineering teams to investigate historical events while maintaining access to high-resolution information.
When machine states, process values, drive parameters, network communication, and external measurements all share the same time reference, identifying relationships becomes significantly easier. The result is a clearer and more complete picture of production behavior during critical events.
Turning Data into Insight
Acquiring process data is only the first step. Engineers must also be able to investigate, compare, and interpret the recorded information efficiently.
This is where ibaAnalyzer plays a central role. The software allows users to visualize synchronized process data, correlate signals from multiple sources, compare operating conditions, and analyze recorded events in detail. By providing a common environment for data evaluation, ibaAnalyzer helps engineers identify patterns, validate hypotheses, and accelerate root cause investigations.
Adding Visual Evidence to Process Data
Although process signals provide essential information, they do not always tell the whole story. Many industrial issues have a physical or visual component that cannot be fully understood through numerical data alone.
Examples include:
- Material positioning errors.
- Product handling problems.
- Intermittent jams.
- Mechanical anomalies.
- Surface defects and quality issues.
To address this requirement, ibaPDA can synchronize process data acquisition with video recording provided by ibaCapture. Together with ibaPDA, ibaCapture records camera images, HMI screens, and measurement data either continuously or event-driven, allowing visual information and process data to be examined together within a common time reference. Important events can also be stored automatically as snapshots for subsequent investigation.
Recorded images become part of the same timeline as machine signals and process measurements, allowing engineers to review visual events in direct relation to recorded process conditions.
This combined perspective enables the simultaneous evaluation of:
- Sensor values.
- Machine states.
- Drive behavior.
- Energy consumption.
- Vibration signatures.
- Camera images captured at the same moment.
When investigating complex production issues, visual context frequently provides crucial information that accelerates root cause identification and reduces uncertainty during analysis.
Proven in Practice
High-resolution data acquisition is already being used across multiple industries to reduce troubleshooting time, improve process transparency, and support root-cause investigations. A number of customer projects illustrate how detailed, synchronized process data can help engineering teams move from assumptions to evidence-based decision-making.

From Fault Analysis to Continuous Improvement
Organizations often introduce high-resolution data acquisition primarily to improve troubleshooting and reduce downtime. However, the value of detailed process information quickly extends far beyond maintenance activities.
The same data that supports fault investigations can also be used for:
- Process optimization.
- Energy efficiency initiatives.
- Quality improvement programs.
- Predictive maintenance strategies.
- OEE improvement projects.
- Reliability engineering studies.
As engineers gain access to more detailed information about machine and process behavior, opportunities for continuous improvement become easier to identify and quantify. Process variations that were previously hidden become measurable, enabling more informed operational decisions.
Over time, high-resolution process data evolves from a troubleshooting resource into a strategic foundation for data-driven manufacturing improvement.
Conclusion
Many industrial facilities already operate sophisticated automation systems but still struggle to identify the root causes of intermittent faults, unexplained quality variations, and recurring production disturbances. In these situations, additional automation is often not the answer. What is missing is detailed visibility into what actually happened during critical events.
High-resolution data acquisition addresses this gap by capturing process and machine behavior at the level of detail required for accurate root cause analysis. Through synchronized recording of automation data, network communication, high-speed analog and digital signals, and even camera images, engineers gain a comprehensive view of production events that would otherwise remain hidden.
By combining detailed acquisition capabilities with a common time reference across multiple data sources, solutions such as ibaPDA enable maintenance and operations teams to move from assumption-based troubleshooting to evidence-based analysis. In an industrial environment where every minute of downtime has a measurable impact on productivity and profitability, the ability to see what truly happened can make the difference between repeatedly treating symptoms and permanently eliminating the root cause.

Questions fréquemment posées (FAQ)
ibaPDA provides continuous acquisition and synchronization of process data, helping engineers investigate disturbances with a much higher level of detail than conventional monitoring systems. While traditional historians are optimized for long-term trending, they often miss fast signal changes and short-lived events that contribute to machine faults. By recording information from automation systems, drives, sensors, and industrial networks in a synchronized manner, engineers can reconstruct events precisely as they occurred. This improves the understanding of timing relationships, signal interactions, and process behavior surrounding a fault. As a result, troubleshooting becomes more accurate, root causes can be identified more quickly, and recurring production issues can be addressed based on objective evidence.
ibaPDA, in combination with dedicated PROFINET monitoring devices, extends diagnostics into the communication layer of industrial automation systems. Instead of relying solely on controller diagnostics, engineers gain visibility into network activity, communication timing, state transitions, and signal interactions across connected devices. This is particularly valuable when investigating sporadic faults that cannot easily be reproduced. Communication-related disturbances often leave little evidence in standard controller logs, making root cause identification difficult. By capturing network-level information alongside process data, engineering teams obtain a more complete picture of system behavior and can correlate communication events with machine reactions more effectively.
ibaPADU is designed for applications that require significantly higher sampling rates than standard automation platforms can provide. By recording analog and digital signals at rates of up to 150 kHz, it enables detailed analysis of fast-changing phenomena such as vibration events, sensor dynamics, energy disturbances, and complex machine behavior. High-speed acquisition helps reveal patterns and interactions that would otherwise remain hidden due to insufficient temporal resolution. This additional level of detail supports more precise investigations of mechanical and process-related issues. For maintenance and engineering teams, the result is improved visibility into critical events and a stronger analytical foundation for diagnosing production losses, quality problems, and equipment-related abnormalities.
ibaHD-Server provides a scalable environment for storing synchronized process data and making it available for long-term investigation. Industrial troubleshooting often requires information from multiple sources, including automation systems, electrical measurements, condition monitoring applications, and quality records. When these datasets share a common time reference, engineers can correlate events far more accurately. Centralized storage preserves this synchronized information and ensures that historical data remains accessible for future analysis. This becomes especially valuable when investigating rare disturbances or evaluating production behavior over extended periods. By maintaining a unified and time-consistent data foundation, organizations can improve both diagnostic accuracy and operational transparency.
ibaCapture, together with ibaPDA, combines synchronized recording of camera images, HMI screens, and process data within a shared timeline. This allows engineers to examine visual evidence alongside machine signals, operating conditions, and measurement data from exactly the same moment in time. Many quality and production issues involve physical events that cannot be fully explained by numerical values alone. By linking images with process information, teams can better understand material handling problems, mechanical irregularities, intermittent jams, or surface defects. The synchronized view significantly improves event reconstruction, helps validate engineering assumptions, and enables more efficient troubleshooting based on both visual and analytical evidence.
