  • G05B 19/042 using digital processors
  • G05B 19/045 using logic state machines, consisting only of a memory or a programmable logic device containing the logic for the controlled machine and in which the state of its outputs is dependent on the state of its inputs or part of its own output states, e.g. binary decision controllers, finite state controllers
  • G05B 19/048 Monitoring; Safety
  • G05B 19/05 Programmable logic controllers, e.g. simulating logic interconnections of signals according to ladder diagrams or function charts
  • G05B 19/06 using cams, discs, rods, drums or the like
  • G05B 19/07 where the program is defined in the fixed connection of electrical elements, e.g. potentiometers, counters or transistors
  • G05B 19/08 using plugboards, cross-bar distributors, matrix switches, or the like
