OPC Automation Interface
The OPC Data Access Automation Interface defines a standard by which automation applications can access process data. This interface provides the same functionality as the custom interface, but in an "automation friendly" manner.
The RSLinx Classic OPC Automation Interface provides a simplified version of the OPC Data Access Automation Interface. This interface facilitates automation client applications communicating to numerous data sources, either devices on a plant floor or a database in a control room, by allowing a Visual Basic client to write the minimum amount of code to read, write, or subscribe to data changes. The interface allows VB applications to exchange data with OPC Server applications.
You can use the OPC Automation Interface to perform tasks such as:
- Getting data into applications such as Excel
- Building a graphic display to get data from a plant floor
- Building a web page and get data to display on the page
