OPC UA
OPC UA is an industrial interoperability standard for exchanging structured data between equipment, software and systems with built-in security capabilities.
SIMPLE EXPLANATION
Open Platform Communications Unified Architecture in context
An OPC UA server exposes a structured information model. Clients can browse approved data, read values, subscribe to changes and, when permitted, write values through authenticated connections.
Example
A gateway can read machine state and production counters from an OPC UA server before sending selected data to a reporting system.
