Before we discuss what an MES is and does, we need a brief history lesson on the use of computers in manufacturing. The late 1960’s saw the first steps of automated manufacturing processes away from electro-mechanical and pneumatic control and towards the use of computers. By the mid-1970’s the Computer-Integrated Manufacturing (CIM) automation revolution was in full swing. The development of manufacturing using digital microprocessor controlspawned software tools that allowed improved manufacturing design and control through use of process modeling and process segment control schemes. Computer integration also allowed the replacement of mimic busses and panel boards with graphic user interfaces. Local unit controllers were developed and the growth and standardization of digital communications connectivity allowed connected controllers to evolve into distributed control systems.
MES concepts originated in the early 1980’s as computer data collection systems became more prevalent. In the middle 1980’s the Purdue Laboratory for Applied Industrial Control had an International Workshop on Industrial Computer Systems
