PURPOSE:To obtain a man-machine input/output device, in a plant monitoring apparatus, wherein it lowers the load of a main processor, it sufficiently utilizes the man-machine characteristic of a subprocessor composed of a single-function computer, it is connected to a dedicated console in conventional pant monitoring systems and its response property is good. CONSTITUTION:A main processor 10 and a subprocessor 30 are connected by a communication line (a). In addition, the subprocessor 30 and an input/output data converter 40 are connected by a communication line (b). A dedicated console 50 is connected to the data converter 40. An input/output operation is performed to the subprocessor 30 from the dedicated console 50. |
