Programmable logic controllers (PLCs) first hit the scene in the late 1960s. The primary reason for designing such a device was to eliminate the large cost involved in replacing the complicated relay-based machine control systems for major U.S. car manufacturers.\u00a0<\/p>\n\n\n\n

Some companies proposed schemes based on the Digital Equipment Corp. DEC PDP-8, the widely-used mini-computer at the time. Dick Morley\u2019s<\/strong> company Bedford Associates in Massachusetts proposed something called a Modular Digital Controller (MODICON). <\/p>\n\n\n\n

The MODICON 084 brought the world\u2019s first PLC into commercial production. Since then, slow steady growth has allowed the manufacturing and process control industries to take advantage of PLC applications-oriented software\u2014programmable language that looks and feels like relay-ladder-logic where any maintenance technician. <\/p>\n<\/div>\n<\/div>\n\n\n\n
