As automation has developed through the years, describe how the role of the operator has evolved.
What will be an ideal response?
In the early days of automation, you might have a single person monitoring a machine that produced something. When the temperature hit a certain point, for example, that person-the operator-might open a valve or turn a knob to make changes and keep the machine functioning properly. As machines became more complex, the role of the operator likewise changed. He or she needed to monitor more functions and, sometimes, more machines. Eventually, computers were brought in to help manage the machines. The overall system that monitors and controls machines today is called an industrial control system (ICS) industrial control system (ICS).
