    摘要: A communication network for an industrial control system permits multiple masters and complex network topologies by transmitting data as packets through paths of nodes on the networks. The packets containing data are preceded by an OPEN message which pre-configured each node with the necessary information to process the stream of succeeding packets in an efficient manner and thus to reduce the necessary overhead in the transmission of each data packet. Each node receiving the OPEN message evaluates its resources and if those resources are insufficient to reliably handle the indicated packets, a message is returned to the originating node indicating that a connection cannot be formed.
