Shows main process steps and main material flow

Time response setpoint variable is planned in advance offline.

Failure results inn hazards for the environment

A hazard occurs

Separate arrangement of structures affecting each other

Compensation of disturbance has priority. Control variable has to remain at a constant value.

Exact and complete description of an automation task using various presentation forms based on evaluation and requirements. 

Termination of the ability of an element to fulfill a function as required

All devices used for controlling including instructions and regulations. Is affected by disturbance variables causing deviation from desired behavior and not known. Using feedback influence of disturbance can be reduced.

Automation is (part of) the product

• Technical process in a device
• Few sensors and actuators
• Engineering and software cost devices by pieces
• Dedicated automation functions
• Microcontrollers and PLCs used
• Large number of pieces (mass product)
• Moderate to high degree of automation (open loop)

Functional unit to process signals with system input variables as a cause being related to system output variables as their effect with time.

Measures causing the desired flow of a process according to defined objectives based on data obtained from the process or environment
