To ensure proper communication, the authentication level of both the server application and the client application The DeltaV OPC History Server provides OPC HDA clients access to raw and interpolated data from the DeltaV Continuous Historian. TCP/IP port 4840: OPC-DA (Data Access) OPC DA deals only with real-time data and not historical data (for historical data you need to use OPC Historical Data Access, or OPC HDA) or events (for Alarms and Events you need to use OPC Alarms The DCOM needs a particular port to be opened in the firewall, in both client and server machine, to have the communication succeed. When an OPC client connects to an OPC server, it connects to port 135 (the RPC port mapper), which assigns one TCP port and one UDP port to the component. Raw data is defined as data that is stored within the historian. However, it is 2) OPC A&E, OPC HDA, OPC DA over XML The OPC Foundation XML service currently only supports the OPC Data Access spec. txt) or read online for free.
