  • Commissioning distributed control nodes
    Patent number: 11750696
    Abstract: Implementations are described herein for commissioning a distributed control node (DCN) to a process automation network. In various implementations, one or more messages transmitted on the process automation network by the DCN announcing that the DCN has joined the process automation network may be detected. Based on the one or more messages, one or more operational technology (OT) capabilities of the DCN may be determined. Based on the one or more OT capabilities, the DCN may be commissioned to the process automation network, e.g., by configuring the DCN to cooperate with one or more other process automation nodes on the process automation network to implement an at least partially automated process.
