A '''process control''' or '''automation system''' is used to automatically control a process such as chemical, oil refineries, paper and [[wood pulp|pulp]] factories.

The PAS often uses a network to interconnect sensors, controllers, operator terminals and actuators.

Line 5 ⟶ 8:

PAS is the lowest level of automation, while MES (Manufacturing Execution System) is considered to be directly positioned above a PAS.

Process automation involves using computer technology and software engineering to help power plants and factories in industries as diverse as paper, mining and cement operate more efficiently and safely.

Line 26 ⟶ 24:

The software and controls regulate equipment to run at the optimum speed that requires the least energy. They also ensure the consistency of quality, meaning less energy is wasted producing products that turn out to be defective, and they forecast when maintenance is needed so less time and energy is spent stopping and restarting equipment for routine inspections.

Major blocks of PAS are: microprocessors,micro controllers and micro computers,multiprocessors,LANs,SCADA,RTU(remote terminal units) and analog and digital I/O modules
