摘要： The control system for a plant comprises a rectifier connected to a network. The rectifier has a unit for acquiring precise time, a unit for sampling the state quantity on the precise time to convert the state quantity into digital data and a unit for adding the precise time at each sampling timing to the digital data to transmit the digital data each having the precise time to the network. A breaker is connected to the network. The breaker has a unit for receiving, through the network, a control command thereto and a unit for transmitting an operating state thereof to the network. A control apparatus is connected to the network. The control apparatus has a unit for performing an operation process on the digital data transmitted through the communication network and the operating state of the breaker transmitted therethrough and a unit for transmitting the control command through the communication network to the breaker in response to a result of the control operation process of the performing unit.
