The industry standards supported by KEPServerEX for real-time connectivity include OPC DA and OPC UA. Dream Report offers an OPC DA and an OPC UA Client connection that can be used to retrieve and set KEPServerEX real-time Tag data. For a local (on node) connection, OPC DA is the best choice as configuration is completely automatic. In Dream Report, you would enable the OPC DA Client interface, browse to the KEPServerEX instance and select it. Once complete, Dream Report will browse tags as you are configuring Report Objects. Note – Dream Report delivers a Data logger that can also log tags to the database of your choice for future reporting.

Dream Report offers some very powerful mapping to data stored in a relational database. A variety of schema formats are supported. The driver enables the user to select a database and table with-in it, and then map to the Date/Time column. Once mapped (typically only done once at the beginning of a project), Dream Report objects can browse the tags from the database and query data based on date/time queries as it would any other historian source.
