Abstract: A relay device (39bA) includes an optical signal return unit (50a) and a detection unit (55b). When an optical signal input via one optical transmission line (41) of two optical transmission lines (41 and 42) with a double-ring configuration has not been detected for a predetermined time or longer, the detection unit (55b) outputs a disconnection signal of the optical transmission line. The optical signal return unit (50a) is configured to, only when there is an input of the disconnection signal, return to one of the optical transmission lines (41) only a clamp beam that has been sent from a representative node via the other optical transmission line (42) in the direction opposite to the optical signal input via the one of the optical transmission lines (41).

Abstract: A method includes estimating a replacement time of a consumable part of a processing device, specifying a timing after substrate processing of the processing device is completed in a period before the replacement time as a replaceable timing of the consumable part, estimating a movement time period required for the part transporting device to move to a position of the processing device requiring the replacement, and estimating a preparation time period required for preparation until the part transporting device moved to the position of the processing device requiring the replacement becomes a state in which the consumable part is replaceable. The method further includes transmitting a replacement instruction to the part transporting device at a timing before a timing that is earlier than the replaceable timing by a total time of the movement time period and the preparation time period, and instructing the replacement of the consumable part.

Abstract: A function of detecting an unused path through which actual data is not transmitted in a long-distance redundant network is realized at low cost. In an optical transmission system 20, each of the optical transceivers 21a and 21b that are connected to each other by an optical fiber cable 22 and disposed separately includes a protocol IC unit 35. The protocol IC unit 35 transmits an idle signal A1 with empty data using an optical signal P1 to an unused path of the optical fiber cable 22. At the time of this transmission, the protocol IC unit 35 outputs, to the transmission unit 33, a control signal C1 for performing, at a fixed modulation period, ON/OFF modulation on the optical signal P1 on which the idle signal A1 is superimposed. Also, the protocol IC unit 35 transmits an OAM signal O1 at an OAM period that is a period different from a modulation period, and performs control to turn ON the control signal C1 at the time of this transmission.
