PI Vision Custom Symbol • Vision Library+
Compare Operational Events Like Never Before
Stop guessing with standard calendar-time trends. Event Comparison Chart+ aligns your PI Event Frames on a relative time axis, empowering you to analyze batches, startups, trips, and golden benchmarks seamlessly inside AVEVA PI Vision.
Advanced Event Alignment Meets Intuitive Interactivity
Powerful Alignment & Scaling
- Relative Time Axes: Align events by Matched Start, Matched End, or completely Normalize them (0–100%) to compare shapes perfectly regardless of duration differences.
- Versatile Layouts: Compare traces using a Single Scale, Multiple Scales, Stacked Lanes, or a powerful Trellis Grid to facet your comparison by asset or severity.
- Child Event Overlays: Reveal internal structure by overlaying child event frames as contextual bands within the parent event.
Golden Benchmarks & Context
- Golden & Tolerance Bands: Turn historical "best practices" into reference profiles. Overlay a golden average trace and generate custom upper/lower tolerance envelopes.
- Pinned References: Keep known "good" or "bad" historical events permanently visible for comparison, even as your current search results update.
- Rich Categorization: Use event attributes to group, color, and organize your events dynamically based on context like operating mode or product grade.
Interactive Diagnostics
- Integrated Action Table: Drive analysis directly from the chart. Hide/show events, pin references, view min/max plot stats, and open PI Event details in one click.
- Dropped Markers: Click anywhere on the plot to drop vertical comparison markers—instantly answering "what do all events look like exactly 5 minutes in?"
- Runtime Event Shifting: Test alignment hypotheses on the fly by shifting events left or right using standard PI duration strings (e.g., 5m, 30s) without editing data.
From Raw Event Frames to Actionable Insights
Batch & Process Optimization
Compare repeated manufacturing batches, cleaning cycles (CIP), or product grades to identify the optimal run shape, reduce variability, and minimize cycle durations.
Startup & Shutdown Analysis
Ensure critical procedures are followed safely and consistently by aligning equipment ramps and shutdowns using the 'Matched Start' or 'Matched End' alignment modes.
Trip & Failure Investigation
Apply 'Pre-Event Offsets' to load critical leading indicators before an event boundary. Anchor failures using 'Matched End' to find the exact moment a process derailed.
Live Fleet Monitoring
Highlight active, in-progress events in real-time. Visually separate live runs from completed history, instantly identifying if current operations are drifting outside of expected limits.
Event Analysis Built for Analysts and Operators
Meaningful X-Axis Alignment
A standard trend tells you what happened at 10:32 AM. This symbol tells you what happens exactly 15 minutes into an event. Use Matched Start, Matched End, or Normalized modes to effortlessly compare events with completely different durations.
Trellis Grid & Layout Options
Too many traces create an unreadable mess. Utilize Single Scale, Split Scales, or the Trellis Grid mode to automatically facet your comparison into smaller, organized panels grouped by asset, severity, or batch grade.
Golden Profiles & Tolerance Bands
Select your best historical runs and hit 'Golden'. The chart automatically builds an average reference profile and wraps it in a custom tolerance band, allowing operators to instantly see when live operations underperform.
Integrated Action Table
Stop hunting for trace colors in a passive legend. The built-in table acts as a workspace: pin references, extract min/max plot statistics, or shift events incrementally (e.g., "30s" left or right) to align signals perfectly.
