The Rise of the Programmable Automation Controller
|
From Advantech Corporation, Industrial Automation Group
It was only thirty years ago that most industrial processes were controlled either by hardwired relay logic or analog loop controllers. It was only thirty years ago that the Space Shuttle's three computer systems had less than 100 kilobytes of RAM and ran their entire complex programs in that space. It was only thirty years ago that there was no such thing as a PC. In the last thirty years, we've come very far from hardwired relays and analog controllers, and computers have changed beyond the belief of anyone in the late 1970s. Product Announcements
