を過大に要するという問題があった。Conventionally, when monitoring loop transmission in an autonomous decentralized double-loop transmission system, the state of the transmission path has been detected by determining phenomena such as an inability to control the terminal or no data being transmitted from the terminal. With this method, when an abnormality occurs, it is difficult to determine whether the terminal is out of order or the transmission line itself is out of order, and there is a problem in that it takes an excessive amount of time and effort to recover the system.

, 10, 11, 12° 13. Each time data from 14 is input, the timeout time is written in the area of the corresponding station in the timeout table 17. The station monitoring program 16, which operates at a constant cycle, subtracts and sets the timeout times of all stations in the timeout table 17 by the cycle. When the result of subtraction is less than or equal to zero, it is considered that the control processing device has failed. Furthermore, if a positive timeout time is set in the timeout table 17 during the failure, it is considered that the system has recovered.
