# Read/Write Operations
The v2 server routes OPC UA Read and Write operations to each driver's `IReadable` and `IWritable` capabilities through `CapabilityInvoker` so the Polly pipeline (retry / timeout / breaker / bulkhead) applies uniformly across Galaxy, Modbus, S7, AB CIP, AB Legacy, TwinCAT, FOCAS, and OPC UA Client drivers. The per-variable `OnReadValue` and `OnWriteValue` hooks described in the sections below live in `DriverNodeManager` (the planned ADR-002 Phase 7 Stream G successor to the v1 `DriverNodeManager`); `GenericDriverNodeManager` (`src/Core/ZB.MOM.WW.OtOpcUa.Core/OpcUa/GenericDriverNodeManager.cs`) handles address-space population and alarm routing during discovery. The current `OtOpcUaNodeManager` (`src/Server/ZB.MOM.WW.OtOpcUa.OpcUaServer/OtOpcUaNodeManager.cs`) is a push-model `CustomNodeManager2` that receives values from the Akka actor layer via `WriteValue`; OPC UA client reads return the cached pushed value.
