Modicon Plc'S4/19/2021
The Modicon PACs have an open architecture with more memory and a simpler system expansion process than PLCs (programmable logic controllers), making them great for complex automation system architectures composed of several PC-based software applications, systems that will need future scalability, and systems with a high percentage of analog IO.Enpirion PowerSoC Modules Integrate Nearly all Components Needed to Build a Power Supply.Historical Engineers: Richard Morley and the Programmable Logic Controller (PLC).
Modicon Plc'S Trial Facilities WithRichard Morley is credited as the person who helped modernize industrial facilities with the invention of the programmable logic controller.Learn about his career, accomplishments, and contributions to the field. While he was reportedly not very motivated in high school, he amazed everyone with his acceptance to the prestigious Massachusetts Institute of technology. His boredom with academic life continued and, by his own admission, he was more interested in pulling pranks, running a bootleg AM radio station, and in his part-time job as a machinist. Despite some formal education at MIT as a mechanical engineer, he left school without a degree. Uninterested in meetings and office politics, he preferred going skiing during the week because the lift lines were shorter. He found the life of a consultant more suitable than that of a 9 to 5er, so he started his own company, Bedford Associates. Over the next ten years, Morley was involved in the creation of the floppy disk, as well as a dazzling array of projects including radar, atomic bombs, and packet radio. Machines still needed to be turned on and off in the proper sequence and the same machines had to respond to other events, such as overheating tanks and excess pressure in valves. In those benighted times, banks of relays and other electromechanical controllers were employed to do the job. And, perhaps worst of all, any changes in the manufacturing process, let alone the need to produce a different product, required the time and effort of skilled electricians to go in and rewire, by hand, each electrical connection between the relays, sequencers, and timers. He described a need in the industry from actual experience and submitted that a modular, rugged system was necessary for reducing downtime. In January of 1968, Morley sketched out the parameters of the first PLC: a rugged, usable controller that could utilize direct mapping into memory and didnt require interrupts for processing. His initial design predated ladder logic by several months, though he apparently had already anticipated the need for that kind of language. Morley and his compatriots at Bedford AssociatesMike Green, Tom Boissevain, George Schwenk, and Jonas Landaudeveloped the idea of a Modular Digital Controller, which quickly got shortened to MODICON. The first such device produced, the Modicon, was the Modicon 084. It took the better part of a decade to gain widespread acceptance. He preferred to find people with interesting ideas and simply fund them and as such considered himself an angel investor. And, to hear him describe it, it seemed like he was always more interested in having techy fun than in actually making money. ![]() ![]()
