A security device includes one or more processors and a memory that includes instructions, that when executed by the processors, cause the processors to perform operations. The operations include monitoring data traffic between industrial automation devices in an industrial system and one or more devices in an external network, determining that a first industrial automation device does not include native security features for receiving secure data from the devices in the external network or transmitting secure data to the devices in the external network, and implementing one or more security techniques in response to determining that the first industrial automation device does not include the native security features.

A method for generating a topology view of an industrial parallel redundancy protocol (PRP) network includes: detecting, by one or more processors, a plurality of nodes on the PRP network; determining, by the one or more processors, a first set of the plurality of nodes that connects to a first local area network (LAN); determining, by the one or more processors, a second set of the plurality of nodes that connects to a second LAN; determining, by the one or more processors, connections between the plurality of nodes; and generating, by the one or more processors, the topology view of the PRP network comprising a topology view of the first LAN and the second LAN according to the determined connections.

To facilitate the commissioning of network identifiers (network IDs), an ordered list comprising network ID's associated with devices of an industrial automation process may be generated and stored. Based at least on the ordered list, a network ID may be identified. A prompt may be generated and displayed, the prompt comprising a notification to power-off one or more devices. Another prompt may be generated and displayed, the prompt comprising a notification to power-on a single device of the industrial automation process. In response to receiving a network-identifier request from the single device, a device identifier may be identified for the single device and stored in a list. A response comprising the network ID and a command to change the assignment mode of the device is autonomously generated and transmitted to the single device, which subsequently stores the network ID changes its mode.

Streamlining the commission of network identifiers

Aspects of the present invention provide a ring supervisor operating as a server for maintaining and allocating addresses for devices in a ring topology. The ring supervisor may obtain an ordered list of devices in the ring by sending a data collection frame that passes through each device around the ring with each device appending its preconfigured address information. The ring supervisor may then operate to apply the addressing provided by each device, or alternatively, allocate different addresses to each device from a separate pool. As a result, control program software for ring devices can be developed using a general pool of addresses without requiring specific knowledge of actual addresses. Also, if a device requires replacement, the device may be replaced without requiring modification to the control program to provide the address for the replacement device.
