OPC DA Client

OPC DA Client 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.
