You have been assigned to a work group that has been given the task of placing automated controls in a chemical plant. Hundreds of sensors will be placed in tanks, vats, and hoppers throughout the factory campus. All data from the sensors will be fed into a group of sufficiently high-powered computers so that plant managers and supervisors can control and monitor the various processes taking place. What type of interface would you use between the sensors and the computers? If all computers are to have access to all of the sensor input, would you use the same type of connection to interconnect the computers among one another? Which I/O control model would you use?
