Line 1:

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

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

A PAS is often based on open standards in contrast to a DCS ([[distributedDistributed controlControl systemSystem]]), which is traditionally proprietary.

However in resentrecent times the PAS is considered to be more associated with [[SCADA]] systems.

PAS is the lowest level of automation, while theMES [[Manufacturing_Execution_System|(Manufacturing Execution Systems|MESSystem)]] areis considered to be directly positioned above a PAS.
