This Part 2 blog of Team82's OPC UA Deep Dive explains the OPC UA protocol and its role in industrial automation, covering its client-server model, the data model where everything is a node (Objects, Variables, Methods, References), NodeIds and namespaces, NodeSet browsing, and binary encoding of types and NodeIds, illustrated with a PLC water-tank example; it is an explanatory/educational piece and does not itself describe any active security incident, though future parts will address security, attack surface, and vulnerabilities.
