Programmable logic controllers were initially adopted by the automotive ind ustry where software revision replaced the rewiring of hardwired control panels when production models changed. Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles was acplished using hundreds or thousands of relays, cam timers, and drum sequencers and dedicated closedloop controllers. The process for updating such facilities for the yearly model changeover was very time consuming and expensive, as electricians needed to individually rewire 安徽建筑工業(yè)學(xué)院 畢業(yè)設(shè)計（論文） each and every relay. Digital puters, being generalpurpose programmable devices, were soon applied to control of industrial processes. Early puters required specialist programmers, and stringent operating environmental control for temperature, cleanliness, and power quality. Using a generalpurpose puter for process control required protecting the puter from the plant floor conditions. An industrial control puter would have several attributes: it would tolerate the shopfloor environment, it would support discrete (bitform) input and output in an easily extensible manner, it would not require years of training to use, and it would permit its operation to be monitored. The response time of any puter system must be fast enough to be useful for control。 the required speed varying according to the nature of the process. In 1968 GM Hydramatic (the automatic transmission division of General Motors) issued a request for proposal for an electronic replacement for hardwired relay systems. The winning proposal came from Bedford Associates of Bedford, Massachusetts. The first PLC, designated the 084 because it was Bedford Associates39。 eightyfourth project, was the result. Bedford Associates started a new pany dedicated to developing, manufacturing, selling, and servicing this new product: Modicon, which stood for MOdular DIgital CONtroller. One of the people who worked on that project was Dick Morley, who is considered to be the father of the Modicon brand was sold in 1977 to Gould Electronics, and later acquired by German Company AEG and then by French Schneider Electric, the current owner. One of the very first 084 models built is
