Data Source Configuration

This dialog box allows you to define the type of connector to be used, and, depending on the type selected, to define the name of the data server and the path to the source.

Type​

This drop-down list defines the type of connector to use. Changing the connector type is only possible when you create a data server.

Properties​

This button is used to configure the general settings of the selected connector, regardless of the source. It is validated only if the selected connector type has general configurable parameters.

Identifier​

This field defines the identifier of the data server that will be displayed by default in the ALERT tree. This identifier is also used in the full identifier of each tag of the data server to reference it, in the form:

<Data Server identifier>.<Tag identifier>

This identifier must be unique in the list of defined data servers.

The data server identifier is usually set automatically from the source name defined in the field below. However, this identifier may be modified, which will be necessary in particular when defining several data servers on the same source (regardless of the location of the external data source).

Source​

This button opens a new dialog box to find and select the data source to be attached to the data server, depending on the selected connector.

Activate debug trace, level​

Check this box to enable debugging trace as soon as the data server is created. You can specify the desired trace level in the adjacent edit field.

Generic connector​

This type of connector is used when the data source is "client" of ALERT and transmits data or alarms on its own initiative through the ALERT OPC server interface of ALERT, the API or command lines. As there is no explicit data source, only the identifier of the data server can (and must) be defined for this type of connector.

Generic OPC connector​

This type of connector is used to interface with OPC DA or AE server applications. Click on the Source button to select the OPC source (OPC server application).

If no name has previously been entered in the Identifier field, this field will be automatically assigned with the name of the selected source (the OPC server reference, regardless of its location).

Generic DDE connector​

This type of connector is used to interface with DDE server applications. Click on the Source button to select the DDE source (DDE server application).

If no name has previously been entered in the Identifier field, this field will be automatically assigned with the name of the selected source (the DDE server reference, regardless of its location), in the form:

<DDE server name>|<DDE topic name>
