摘要： The present invention provides a duplexed operation processor control system that includes operation processors, an I/O device, and at least one communication path that couples the operation processors to the I/O device, and at least one communication path that couples the operation processors with each other. The duplexed operation processor control system switches over either of the operation processors to be a primary operation processor that executes a control operation for a control target, and the other to be a secondary operation processor that is in a stand-by state, and the secondary operation processor snoops control data synchronously when the primary operation processor acquires the control data from the control target.

摘要： A plurality of radio relay stations 1 are connected so that bi-directional ring-like paths are made up of radio transmission paths. The respective radio relay stations 1 bidirectionally transmit data inputted from terminals placed thereunder onto the bidirectional ring-like paths respectively. The respective data are respectively received by radio relay stations 2 having data destination terminals placed thereunder along the bidirectional ring-like paths. Each radio relay station, which has received the data destined for the terminals placed thereunder from both directions, transmits earlier incoming data to each terminal placed thereunder and discards later incoming data. Thus, a radio relay system can be implemented which is capable of relaying data with a high degree of reliability.

摘要： PROBLEM TO BE SOLVED: To change a branch connection device, to which a computer device is connected, from stand-by state to working state in a short time.SOLUTION: When a branch connection device requires initialization, a control command unit 123b sets the function by resetting a relay processing unit 121b and a relay control unit 122b included in the branch connection device. The control command unit 123b does not reset a plurality of physical layer processing units 111b-113b, at this time. Since time-consuming setting is not carried out during initialization, the branch connection device can be changed from stand-by state to working state in a short time.

摘要： PROBLEM TO BE SOLVED: To send/receive device data independently of a controller in a control system where pluralities of devices such as sensors and actuators are partially multiplexed. SOLUTION: Device model information assigned definitely by a model and an operation is set to a register 16 with respect to devices 20-1-20-n connected by device connection sections 14-1-14-n of the communication controller 2. An MPU 4 stores the device model information corresponding to the devices 20-1-20-n to a table 101 for each IF/No and in the case of receiving data of a reception buffer 18 of each device I/F section 15, corresponding device model information is provided and copied to a transmission buffer 103 and sent to a network 1 via a communication protocol control section 8. When the device model information corresponds to pluralities of IF/Nos, only data of the priority device side are sent. Furthermore, the device model information provided in data received from the network 1 corresponds to pluralities of IF/Nos, data are transferred to pluralities of corresponding devices 20-1-20-n.
