Abstract
An autonomous distributed field bus system includes a host apparatus disposed in a control room, a plurality of detection and control blocks disposed in a field, and a bus line for connecting the host apparatus to the plurality of blocks. Each of the plurality of control blocks includes a detection device, an arithmetic and control device and an operating device, and forms a control loop. The arithmetic and control device produces a control signals by using control parameters stored therein on the basis of the measured value detected by the detection device. The operating device is operated by the control signal. Control operation is thus performed in each of the blocks without participation of the host apparatus.
