Create structured, vendor‑neutral functional specifications following ISA‑88, ISA‑106, MTP and AAS principles. FSS guides process engineers through defining states, commands, parameters, interlocks, and operational sequences at Plant, Unit, EM, and CM levels, ensuring complete, compliant and consistent specifications across the engineering lifecycle.

Import P&IDs via DEXPI to automatically extract equipment, instrumentation, and connections. Define and validate operational sequences directly on the P&ID using visual highlights and step‑through animations, enabling clear communication between process and automation engineering teams and preventing misunderstandings early in the design phase.

Build standardized libraries of Equipment Modules (EMs), Process Equipment Assemblies (PEAs), and Control Modules. FSS automatically identifies patterns in imported P&IDs and suggests matching types. Changes to a type propagate to all instances, ensuring consistency and reducing engineering time across similar equipment. Supports variant management and reuse across projects.

FSS detects P&ID revisions, highlights modified components, and automatically identifies affected equipment modules, sequences, control loops, and specification objects. Engineers can review, update, and approve changes with full traceability and version control, reducing risk of overlooked dependencies and avoiding costly late‑stage corrections.
