Key Features
- Versatile technology: Leverage the AVEVA PI System or your preferred data historian; integrate readily with existing software and hardware at any scale.
- User-friendly configuration: Easily configure for site-specific permit conditions, instrumentation, business processes, and applicable regulations.
- Automated acquisition: Monitor data and analyzer status from the field; capture calibration drift checks, maintenance status, fault signals, and overrides.
- Data validation: Automatically validate data every hour via transparent, real-time calculations, retrospective recalculation, and calibration drift correction to produce rollups and aggregated totals.
- Evaluation and notification: Immediate notification of invalid data, analyzer faults, and out-of-control events; integrated tracking of downtime, exceedance, and reason/action codes.
- Advanced automation: Compliance averaging using quality-assured, validated data; automated preparation of calibration, EEMSP, EDR, and custom reports.
How it Works
Unlike most environmental reporting systems, PI-DAS doesn’t operate in a silo. Built directly on the PI System, PI-DAS houses all environmental compliance data in the same ecosystem as your operational data.
- Raw data from analyzers and instrumentation is stored in PI
- Real-time validation and averaging are applied using rules-based logic
- Final and intermediate results are written back into PI
- Data is viewable in dashboards and ready for export in reports.
- Full calculation traceability and transparency make audits simple
Key Capabilities
Acquisition: Real-time acquisition of raw data into the historian
- Raw data, analyzer status from PLC’s, DCS’s, CEMS
- Calibration gas values, maintenance status, fault signals
- Heating values, F factor, moisture, etc.
Validation: Raw data validation, range, in-control & roll-up to averages
- Real-time block and rolling averages
- Automatic exclusion from averages of invalid data due to fault or maintenance
- Out of control determination and drift correction
- Timely notification of invalid data, analyzer faults, out-of-control (OOC)
Roll-up: Hourly and block average
- Timely notification of exceedances – emission, concentration, opacity
- Prompting for R&A inputs for monitoring equipment malfunctions and exceedances
- Missing data procedures, if required
Aggregation: Aggregation of hourly and block data to daily, monthly, and quarterly values by emission source and/or facility
Reporting: Automatic data transmission and reporting to regulatory agencies; production of operational and compliance reports (EDRs)
Advanced automation: Compliance averaging using quality-assured, validated data; automated preparation of calibration, EEMSP, EDR, and custom reports.

Proven Performance in Demanding Real-world Environments
“Because EXELE is supporting us, I don’t need to worry about the system at all. I don’t think about it. I don’t fret over it. I know they got it. Peace of mind is the best way to describe it.”
“Their customer service, accessibility, and willingness to do what you need them to do on a regular basis. I’ve never heard them say, “No.” It’s always, “What do you need? We’ll take care of it.”
“It used to take us several hours to review some of the requirements. Once we installed PI-DAS, it went to 15 minutes… We literally cut hours out of our audits. It was a game changer.“
