Calvin Schelberg:  

Chuck Schelberg’s professional bio Email: ChuckSchelberg at GMail dot com Chuck Schelberg is an industrial controls architect and programmer. He has been deeply involved with the concept, design, and implementation of a wide variety of industrial systems ranging from embedded motion controls, to parallel processor database systems, to communications gateways, to laboratory and medical equipment. He was a member of the Dick Morley team that developed the Programmable Logic Controller (PLC) at Modicon. The PLC was the first computer accepted on the manufacturing floor. Every automated process used in manufacturing today uses PLCs. The PLC is the most prolific computer system to date. Of all the microprocessors made today the overwhelming majority become PLCs with the remainder going into cars, phones, tablets, and personal computers. Besides developing all of the original Modicon PLC software Mr. Schelberg was instrumental in developing all of the early Modicon advanced programming language functions (DX line) along with many of the PLC peripherals. Not a fan of the “Go To” statement Mr. Schelberg successfully developed the “Go From” method of programming which is the basis for the PLCs ladder logic. Mr. Schelberg was part of the team that developed the soft drum sequencer used in the first model of the SunKeeper building controller. That effort became today’s Andover Controls the world’s leading “Smart Building” management system manufacturer. Mr. Schelberg has successfully brought the science of chaos to bear in solving two classical process problems. One within a General Motors paint shop to minimize the number of color changes within the ten paint booths saving GM over $10K per paint booth per month. The second being the scheduling of autonomous pick and place robots to increase the throughput of critical object placements on an automated laboratory bench by 25%. Other contributions of Mr. Schelberg’s to the process automation field include ...Expand for more
