Sequence of Event Recorder - analyze switching operations, monitor processes, avoid faults
In industrial plants, it is crucial to record switching operations, alarms and status changes precisely and with high temporal resolution in order to control processes reliably and detect faults at an early stage. Our sequence of event recorders work closely with SCADA systems and enable seamless recording and analysis of all relevant events - for efficient process monitoring and reliable fault diagnosis during operation.
What advantages does a Sequence of Event Recorder with Delphin offer you?
- Precisely record switching operations: Digital and analog signals are recorded in parallel with µs resolution in order to reliably document even fast switching times and relay bounce.
- Detect and rectify faults quickly: Real-time monitoring enables immediate reactions in the event of deviations, thus avoiding or shortening downtimes.
- Analyze processes in detail: Switching times and process sequences are recorded in a traceable manner and can be conveniently evaluated using the measurement technology software.
- Document events without gaps: Triggered storage with pre- and post-history for complete traceability during audits and internal analyses.
- Self-sufficient operation for maximum availability: Data can also be recorded without a PC so that tests and production processes are not interrupted.
- Increase process reliability and efficiency: Sources of error are identified, processes optimized and system availability sustainably improved.
The combination of Sequence of Event recorders and SCADA systems enables efficient and safe process monitoring. Typical areas of application are
- Fault analysis on systems, machines and devices
- Qualification and validation of systems
- Checking PLC programs and logic analysis
- Determining the switching times of temperature controllers
Practical example of a Sequence of Event Recorder
Precisely detect and analyze malfunctions and switching times in locomotives
A leading manufacturer of locomotives uses ProfiMessage D devicesto reliably record and evaluate faults and switching times during operation. This is crucial to ensure the long-term availability and operational safety of locomotives and to minimize downtimes. During operation, digital signals from control units, relays and contactors are recorded with high temporal resolution in order to reliably document even short switching operations or contact bounce. CAN data is recorded in parallel, as several CAN buses are used in modern locomotives for communication between the various subsystems such as the drive, brakes or door control. This enables comprehensive diagnostics, as all relevant system information is available synchronously.
In addition, GPS data is recorded and synchronized with the operating data so that the driving and load profiles are linked to the exact position of the locomotive. This makes it possible to trace the driving conditions under which faults or anomalies occur, for example on specific gradients, speeds or depending on braking processes. The data can be read out flexibly via service laptop, USB stick or, if required, directly and promptly via a UMTS router. This makes it possible to carry out analyses and fault diagnoses immediately after a fault occurs in order to initiate quick measures and reduce downtimes. The measurement software clearly visualizes the recorded data and enables a detailed evaluation of switching times, malfunctions and driving profiles. In this way, sources of faults can be specifically identified, processes optimized and service and maintenance processes made more efficient.
