The OPC Server for Wonderware Historian adds support for the current version of the Wonderware Historian as well as for the latest Microsoft Windows operating systems, including Windows 7 (32-bit and 64-bit versions), Windows Server 2008 and Windows Server 2012 (64-bit). The product now includes support for performing real-time (OPC DA) and historical (OPC HDA) writes to the Wonderware Historian on top of its original read capabilities. This allows users with OPC-enabled client applications such as HMI (SCADA) software or other applications to send data to the Wonderware Historian directly through this server.
