Control systems are robust by design and development and therefore tolerant towards occurring issues. Non-optimal system settings and conditions often do not cause incidents immediately, but might result in disturbances over time.
What could happen in long-term running systems:
- System overload is causing slow response rate
- Gradual system performance degradation is not diagnosed or resolved until issues arise
- Issues arise sporadically which are difficult to diagnose
- Hardware devices glide slowly towards unavailability
- Redundancy problems create single points of failures
- System efficiency losses
- Unavailability of operational features due to lacks in software installation
- Security vulnerabilities due to obsolete Microsoft Update status
Therefore, various reports and services have been developed on the base of long-term customer support experience, with automated data collection and report generation.
