TLDR
In this paper, the presence of a fault and a faulty section on a loop transmission line are specified by receiving packet data at a sender and applying operation it with a specific constant in the own equipment.Abstract:
PURPOSE: To specify the presence of a fault on a loop transmission line and a faulty section by receiving packet data at a sender and applying operation it with a specific constant in the own equipment. CONSTITUTION: When a packet sender sends a packet #i, a specific constant M is set to a control section CTL provided at the outside of operation object of the packet #i and the result is sent. In a data transfer device Ni other than the sender connected in a loop, the packet #i is received and only when an error is detected, operation is applied to the content of the control section CTL. Then the transmission of the packet to the data transfer device Ni of the next rank is repeated, the sender receives the said packet data #i to apply operation with the specific constant N in the own device. Thus, the presence of a fault and the faulty section on the loop transmission line are specified. Thus, even when the loop transmission line consists of many transmission line sections, a faulty section of the transmission line is located easily. COPYRIGHT: (C)1986,JPO&Japioread more

Device for detecting the position of broken line in a series controller
TL;DR: In this article, the authors proposed a method for detecting the position of broken line in a series controller wherein peripheral processing devices indirectly control the sensors and the actuators, and these peripherals are connected in series via signal lines in an annular manner via a central processing unit or in a serial manner relative to the central processing units such that position of breakage on the signal line can be detected.
