Accessing Data Using OPC UA

OPC UA provides a great deal of scalability and flexibility in data access. For example:

1. An OPC client accessing an item in an OPC UA data source:

   1. Connection: OI.Gateway.1

   2. Item Reference: OPCUA1.Topic1.Device1.TankLevel

2. A SuiteLink client accessing an item in an OPC UA data source:

   3. Connection:

      1. Application: OI.Gateway

      2. Topic: OPCUA1_Topic1

   4. Item Reference : Device1.TankLevel
