Class SystemInstrumentDesign

java.lang.Object
neqsim.process.instrumentdesign.system.SystemInstrumentDesign
All Implemented Interfaces:
Serializable
public class SystemInstrumentDesign extends Object implements Serializable
Plant-wide instrument design summary.

Aggregates instrument requirements across all equipment in a ProcessSystem, calculates total I/O counts, DCS/SIS cabinet requirements, and total instrument CAPEX. This class complements equipment-level instrument designs by providing a system-level view for control system sizing.

DCS and SIS sizing follows typical I/O density rules:

  • DCS: ~64 AI channels per I/O card, ~16 cards per cabinet
  • SIS: ~32 channels per I/O card, ~8 cards per cabinet (redundant)
  • Marshalling: 1 cabinet per ~200 I/O channels
