Overview

Product Overview

OPC DA stands for OPC Data Access. OPC Data Access (OPC DA) provides access to real time automation data. Using OPC DA, software applications can retrieve real-time data to enable them to monitor a given process.

The OPC DA Client driver and Kepware communications platform provide an easy and reliable way to connect disparate third-party OPC DA servers to your client applications, including HMI, SCADA, Historian, MES, ERP, and countless custom applications.

With the OPC DA Client driver you can manage operations through a single server interface, so there is no need to learn the different nuances of other third-party servers.

This driver also enables Oracle MES and MOC users to bring Kepware OPC operations and all other third-party OPC operations into your business applications.
