Abstract
SPECIFICATIONS for a supervisory system have been modified only slightly during the last few years, and usually require the following: reliability, low maintenance, high speed, simplicity, flexibility, minimum connecting wires, and good appearance. The requirement of minimum interconnecting wires especially is important when the control is to be extended any distance.
