Abstract :
An overview of the evolution of distributed real-time controllers in aerospace manufacturing environments is given. Programmable logic controllers (PLCs) and projected PLC market revenues are reviewed, as well as manufacturing deployment strategies and customer support. The hidden costs of PLC technology are identified. Examples of today´s state-of-the-art parallel distributed real-time manufacturing systems are given. Large hidden support costs associated with such systems are identified. In conclusion, ideas on how new real-time distributed systems can be supported by the current corporate philosophy of speed, quality and cost, are discussed. Techniques of how to move forward to the implementation of new real-time distributed systems are presented
