Learning Outcomes
Understand the ISA-95 control hierarchy from process level to enterprise planning
Distinguish between DCS, IPS/SIS (SIL-rated), and FGS safety systems at Level 1
Identify field instrumentation: TT, PT, FT, LT transmitters and final elements
Explain how SCADA and operator workstations provide supervisory visibility at Level 2
Trace how process data flows from field instruments through to ERP systems
Apply ISA-95 knowledge to plant automation design and system integration projects
