The physical process — This level defines the
ISA-95 Functional Layer
physical processes showing data flowing from
Level 0
sensors and actuators into the control level.
Intelligent devices — Devices in this level sense and
manipule the physical processes. Process, sensors,
ISA-95 Functional Layer analyzers, actuators and related instrumentation.
Level 1 This layer shows how PLCs receive field device data,
process it, and then send commands back to the
field devices.
Control systems — Supervising, monitoring and
controlling the physical processes. Real-time
controls and software; DCS, human-machine
ISA-95 Functional Layer interface (HMI); supervisory and data acquisition
Level 2 (SCADA) software. This level represents how the
control systems manage PLCs, how operator
commands are processed, and how alarm
conditions are handled.
Manufacturing operations systems — Managing
production workflow to produce the desired
products. Batch management; manufacturing
ISA-95 Functional Layer execution/operations management systems
Level 3 (MES/MOMS); laboratory, maintenance and plant
performance management systems; data historians
and related middleware. Time frame: shifts, hours,
minutes, seconds.
Business logistics systems — Managing the business-
related activities of the manufacturing operation.
ERP is the primary system; establishes the basic
plant production schedule, material use, shipping
ISA-95 Functional Layer
and inventory levels. Time frame: months, weeks,
Level 4
days, shifts. This level shows how enterprise systems
deal with production planning and overall business
logistics, and how this information is sent down to
lower levels.
