For every server with which you want Geo SCADA Expert to communicate using the OPC XML-DA protocol, you need to configure an OPC XML-DA Server in the Geo SCADA Expert database.
Before configuring an OPC XML-DA Server in the database, carry out any necessary Preparation. Then use the fields on the OPC XML-DA Server Form to configure the OPC XML-DA Server database item(s) on your system.
The Form has several tabs. Use the fields on the Server tab to define the connection properties that are required for successful communications with the node on which the OPC data is located (see Configure the OPC XML-DA Server Properties).
For information on the fields on other tabs, see Tabs That are Common to Many Configuration Forms in the Geo SCADA Expert Guide to Simple Drivers.
For information on the minimal amount of configuration that you can undertake to produce a functional OPC XML-DA Server in Geo SCADA Expert, see Minimum Configuration.
