PAS inBound application to identify safe operating limits

inBound is a layered application for PAS's PlantState Suite alarm management software that makes plant operators continually aware of safe operating limits.

The product aggregates, validates and displays physical constraints such as a vessel’s Maximum Allowable Working Pressure (MAWP), design constraints, such as relief valve settings, and safe operating limits. These constraints may be manually entered, calculated, or imported into the software from engineering applications and databases.

The application enables engineers to develop a boundary hierarchy and automatically detects and reports deviations from that hierarchy, such as an alarm setting that is higher than a pressure-relief valve setting. This capability provides assurance that configuration parameter changes, such as alarm limits and instrument ranges, remain within the safe operating envelope of the plant.

By displaying safe operating limits in real time and in context within the plant’s existing control system graphics, the product enables operators to proactively monitor measurements and take action, as needed, to prevent violation of limits.
