Abstract: A system is provided in which a position for each device (relative to other devices) in a topology, and a corresponding device ID for each device, may be predetermined. Then, the predetermined position and corresponding device ID for each device may be compared to actual devices in a topology having preprogrammed device ID's and pre-assigned IP addresses. If the comparison produces a match, the pre-assigned IP addresses in the actual devices may be utilized. However, if the comparison does not produce a match, the condition may be reported for further action.

Abstract: IP addresses may be allocated to devices in an industrial control system by applying starting address information in combination with each device's relative position in a local network. The starting address information, which may include an IP subnet address, gateway address, subnet mask, subnet size, and/or local network group identifier, may be provided to a first positioned, or “initiator,” device in a local network. The initiator device may determine its IP address by applying the starting address information and knowledge of being the first positioned device. The initiator device may send the position information and at least a portion of the starting address information to a next device, which may determine its relative position based on the received position information, and which may apply its relative position with the portion of the starting address information to determine its IP address. This process may continue sequentially for each device.

Abstract: An electronic device in an industrial control system may be connected as a network device, such as via EtherNet/IP. The device may be configured to provide an “unconnected” message notification (or “active report”) when the device detects an enumerated condition, such as an error or deviation. An unconnected message may be a message sent between two or more applications (which may be of the same or different devices) without pre-established communication channel bindings. An unconnected message may include routing path information for routing the message to the host computer, application path information for associating the applications, and data payload information related to at least one of a state of the electronic device and the enumerated condition.

Abstract: For predicting industrial automation network performance, a method generates algorithm parameters in a first standard format for a network calculus model from design data for a network implementation. The method generates the network calculus model from the algorithm parameters. The network calculus model models worst-case performance for the network implementation. The method generates model parameters in a second standard format for a network simulation model from the design data. The method generates the network simulation model from the model parameters. The network simulation model models probabilistic performance for the network implementation. The method executes the network calculus model to determine network calculus results. The method executes the network simulation model to determine network simulation results. The method determines a system policy difference between the network calculus results, the network simulation results, and the system policy. The method updates the design data based on the system policy difference.
