Abstract:
1. A conveyance control system, comprising: a plurality of data processing slave stations connected through a common transmission line, wherein a first data processing slave station of the plurality of data processing slave stations obtains information about a predetermined station from monitor/control data about the plurality of data processing slave stations transmitted to the common transmission line, determines and adjusts control/monitoring of the first data processing slave station, and outputs information about the first data processing slave station to the common transmission line, a frame of the monitor/control data transmitted on the common transmission line includes a series of input/output signals of a plurality of addresses subsequent to a start signal, which represents a start of transmission, and continuing to a next start signal, each address indicating a position in the monitor/control data frame, and is divided into at least an input period and an output period subsequent to the input period, data being output from a mediation station or a master station to the first data processing slave station during the output period, data being input from the first data processing slave station to the mediation station or the master station during the input period, and the information about the first data processing slave station output to the common transmission line from the first data processing slave station is obtained by a different data processing slave station, as a part of the monitor/control data, and becomes a control/monitor factor of the different data processing slave station, wherein the plurality of data processing slave stations obtain information in the monitor/control data frame synchronously from the common data transmission line without being transmitted through the master station or the mediation station, wherein the common transmission line comprises a common conductor that is configured to transmit the monitor/control data and to transmit electric power, and wherein each of the plurality of data processing slave stations includes a RAM storing the monitor/control data about the plurality of data processing slave stations.
