Solution  ·  PI System Data Resiliency
Make your PI System reliable enough for operations, analytics, and AI
Industrial teams depend on PI data every day, but years of tag sprawl, inconsistent AF models, fragile interfaces, undocumented calculations, and site-by-site configuration decisions make the system hard to trust. Tycho helps PI teams find what is broken, understand what depends on it, and prioritize cleanup before bad data spreads downstream.

Why PI data resiliency matters

PI is no longer just a historian. It feeds operations, dashboards, reliability programs, analytics, enterprise data platforms, and AI initiatives. The quality and reliability of PI data now determines whether those investments deliver real value.

Operations

Operators rely on PI Vision displays for real-time decisions. Stale or incorrect data drives bad decisions at the worst moments.

Analytics & Reporting

Reports, dashboards, and KPIs pulled from PI are only as good as the tags and AF models underneath them.

AI & Digital Transformation

AI initiatives built on unreliable historian data fail. Resiliency is the prerequisite, not an afterthought.

Common PI failure modes

Most PI environments have accumulated years of technical debt that is invisible until something breaks. These are the most common failure modes Tycho surfaces.

Tag sprawl & stale tags

Thousands of tags with no active data, no owner, and no record of whether anything depends on them.

Broken AF analyses

Analyses referencing missing, renamed, or invalid tags silently producing bad results across asset hierarchies.

PI Vision display issues

Displays showing bad values, missing data, or crashing because of expensive calculations or broken upstream references.

Duplicate & orphaned tags

Multiple tags measuring the same signal with no record of which is canonical, used, or safe to remove.

Untracked changes

Tag configurations, AF expressions, and templates changed without visibility into what broke downstream.

Missing metadata & weak ownership

No record of who owns a tag, what it measures, or what depends on it. Institutional knowledge walks out the door.

What Tycho monitors across your PI estate

PI Tags

Tag health, stale values, bad data, missing data, compression issues, usage, ownership, and naming consistency.

AF Attributes & Analyses

Template consistency, broken analyses, invalid tag references, expression changes, and calculation reliability.

PI Vision Displays

Display-level calculations, symbol dependencies, stale references, performance issues, and operator-visible bad values.

Interfaces & Connectors

Interface health, data flow gaps, upstream source failures, and connector reliability.

Change History

Track changes across tags, AF objects, templates, and calculations so every modification is traceable.

Security & Access

Security configuration consistency, access patterns, and configuration drift across sites and systems.

From health check to operating model

Most PI health checks produce a report that sits on a shelf. Tycho is ongoing observability: a continuous view of what is healthy, what is degrading, and what changed. PI teams move from reactive firefighting to proactive management of their data infrastructure.

1

Assess

Surface existing issues across tags, AF, displays, interfaces, and change history. Build a clear picture of what is broken and what is at risk.

2

Prioritize

Not all findings matter equally. Focus cleanup and remediation on issues with the highest operational impact, downstream dependencies, and cleanup risk.

3

Monitor

Maintain ongoing visibility so new issues are caught early, changes are tracked, and the PI estate stays reliable as it evolves.

Business outcomes from PI data resiliency

Less
Manual investigation time spent tracing tag issues and display failures
Safer
Tag cleanup and AF changes with full downstream dependency visibility before acting
Ready
PI data prepared for AI, analytics platforms, and enterprise data initiatives

Explore specific PI resiliency topics

Each page covers a distinct area of PI data resiliency in depth.

Tag Management

PI Tag Cleanup & Lifecycle Management

Find unused, stale, duplicate, and orphaned tags. Understand blast radius before cleanup. Reduce cost and complexity safely.

Change Management

PI & AF Audit Trail / Change Impact

Know who changed what in PI and what it affected. Traceable changes across tags, AF objects, and calculations.

Display Reliability

PI Vision Performance & Display Trust

Stop guessing why PI Vision displays are slow or wrong. Trace display values back to source and fix the right thing first.

AF Governance

AF Governance & Calculation Reliability

Bring order to the AF wild west. Find broken analyses, enforce template consistency, and make AF usable for enterprise analytics.

AI Readiness

PI Data Readiness for AI & Enterprise Analytics

AI will not fix unreliable PI data. It will amplify it. Build the reliable foundation that AI initiatives actually require.

Assessment

PI Gap Assessment & Modernization Roadmap

Turn PI technical debt into a prioritized modernization roadmap. Assess the full PI operating layer and know what to fix first.

Assess your PI data resiliency

Find out where your PI estate has reliability gaps, what is at risk, and what to prioritize. A focused assessment that surfaces the issues that matter most.
