Levels
Plant Level (Level 0)
Includes physical equipment like Sensor, Actuator, Motor, Pump, etc
Controller Level (Level 1)
Involves real-time control of physical devices like PLC that can recieve input from sensors on plan level.
Coordinating Computer Level (Level 2)
Involves supervisory computers or HMI systems that provide centralized views of plant operations. Often collects data from level 1 controllers and display them
Program Logic Controller Level (Level 3)
Level includes controlling overall production processes. Includes advanced software systems that can coordinate multiple production lines and log for analysis.
