Add and configure an OPC HDA data connection

An OPC HDA Connection is an item that you add to an OPC HDA data source in the Project Explorer. It specifies connection settings to an OPC HDA server; such as the computer name, server ID, and timeout settings.

The data connection uses pinging, which is a mechanism to monitor the health of the connection to verify valid connectivity. AVEVA Production Management displays the connection status in the ConnectionState property of the data connection.

A project can contain more than one data source, but a data source can contain only one data connection.

Prerequisite

Add the data source before adding the data connection.

To add an OPC HDA connection

1. In the Project Explorer, right-click the data source, and then click Add Connection. An OpcHdaConnection item appears.

   

2. Rename the item with a meaningful name.

3. Configure the properties. For guidance in configuring the properties, see OPC HDA data connection properties.
