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 sensors, actuators, computer technology and software engineering to help power plants and factories in industries as diverse as paper, mining and cement operate more efficiently ...

Industrial process control (IPC) or simply process control is a system used in modern manufacturing which uses the principles of control theory and physical industrial control systems to monitor, control and optimize continuous industrial production processes using control algorithms.
Before, control logic for manufacturing was mainly composed of relays, cam timers, drum sequencers, and dedicated closed-loop controllers. [3] The hard-wired nature of these components made it difficult for design engineers to alter the automation process. Changes would require rewiring and careful updating of the documentation.
ANSI/ISA-95.00.03-2005, Enterprise-Control System Integration, Part 3: Models of Manufacturing Operations Management focuses on the functions and activities at level 3 (Production / MES layer). It provides guidelines for describing and comparing the production levels of different sites in a standardized way.
The use of automation in manufacturing started by using technologies such as pneumatic and hydraulic systems in applications where their mechanical advantages could be used to raise output quality and efficiency in production. [8] Complex and highly integrated systems have since evolved, composed of procedures with sophisticated operation ...
Systems acting on ISA-95 Level 2 are supervisory control and data acquisition (SCADA), programmable logic controllers (PLC), distributed control systems (DCS) and building automation systems (BAS). Information flows between MES and these process control systems are roughly similar: To PLCs: work instructions, recipes, set points
ISPE has published a series of good practice guides for the industry on several topics involved in drug manufacturing. The most well-known is The Good Automated Manufacturing Practice (GAMP) Guide for Validation of Automated Systems in Pharmaceutical Manufacture. The second edition (GAMP5) was released in July 2022.
