Add and configure an OPC HDA status variable

We recommend adding OPC HDA status variables to OPC HDA data connections. Before you can add a status variable, add an OPC HDA group.

To add an OPC HDA status variable

1. In the Project Explorer, right-click the group, point to Add Item, point to OPC HDA Connector, and then click StatusVariable. An item OpcHdaStatusVariable appears.

   

2. Rename with a meaningful name.

3. Configure the properties. For guidance in configuring the properties, see OPC HDA status variable properties.
