For every server with which you want ClearSCADA to communicate using the OPC protocol, you need to configure an OPC Server in the ClearSCADA database.
Before configuring an OPC Server in the database, carry out any necessary Preparation. Then use the fields on the OPC Server Form to configure the OPC server database items 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 Configuring the OPC Server Properties).
For information on the fields on other tabs, see Tabs That are Common to Many Configuration Forms in the ClearSCADA Guide to Simple Drivers.
For information on the minimal amount of configuration that you can undertake to produce a functional OPC Server in ClearSCADA, see Minimum Configuration.
