New here?

Start with Start using WS.PEMS. Then find a screen and learn the key concepts.

Main tasks

• Monitor live values on the Overview page and the process view.
• Respond to an alarm.
• Generate a report or a composed report, and look at history in the data explorer.
• Trace a reported value back to its inputs.

Configuration and assurance

• Calibrate and validate: the measurement, calibration and validation workflows, and uncertainty without a calibration.
• Set up and maintain the system: administration, fuels, models, pipelines and jobs.
• Ask PEMS answers questions about your plant data.

Which screens you can open depends on your role and on the modules your installation has enabled.

Understand and look up

How emissions are calculated, reporting periods and limits, data lineage, composed reports and the regulatory frameworks. Look up the report catalogue, the standard tags, the units and the glossary.
