Minimum Configuration - OPC UA Servers

When you add an item to the database, various properties on the item's configuration Form are assigned a value automatically. These default values are assigned on creation of the database item, to help reduce the amount of manual configuration that is required. As such, you only need configure a subset of the properties that exist on an item's configuration Form. Typically, the properties you have to configure include:

• Those properties that require a value, but for which the property field is blank
• Those properties for which the value needs to differ from the default.

For an OPC UA Server to be capable of functioning in Geo SCADA Expert, as a minimum you have to specify these properties on the item's configuration Form:

• The Server URL address
• The Server Certificate and Authentication criteria (if required to access the server).

Also ensure that the OPC UA Server and the database items on which it depends are In Service, and have saved, valid configuration. This will produce an OPC UA Server that is capable of functioning using the default configuration settings.
