摘要： A communication method operates to seamlessly transmit internet protocol (IP) data frames, such as IPv6 data frames, over a communication network that uses a non-IP network routing protocol, i.e., a communication network that implements a network routing protocol other than, or that is incompatible with an IP network routing protocol, such as the WirelessHART protocol. This communication method enables, for example, field devices or other intelligent devices within a process plant network that uses a non-IP communication network to perform messaging of IP data frames generated at or to be received by internet protocol enabled devices either within the process plant network or outside of the process plant network.

摘要： A first node sends a first message to a second node. The second node sends a second message to the first node. A first elapsed time is measured from the beginning of the transmission of the first message to the beginning of receipt of the second message. A second elapsed time is measured from the beginning of the receipt of the first message to the beginning of the transmission of the second message. The second node sends a third message to the first node containing the second elapsed time. The distance between the first and second node is calculated based on these elapsed times and a calibration count multiplier contained in the second or third message. A node may be moved within a wireless mesh network. Positional information about the node and distances to its neighbors is determined and transmitted to the network manager where it is stored.

摘要： An interface module is operatively connected to a Fieldbus process control network and to at least one non-Fieldbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to corresponding process control parameters of the non-Fieldbus process control network. Once the Fieldbus process control parameters are mapped to the non-Fieldbus process control parameters, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the database. The interface module may also function in the other direction to map non-Fieldbus process control parameters to corresponding Fieldbus process control parameters.
