The Connectivity Explorer application (for Windows only) allows the user to navigate through hierarchy of OPC Data Access and OPC Unified Architecture servers and data nodes. The user can subscribe to data changes, and view the results live.

Features of Connectivity Explorer include:

• Selected data can be transferred to Excel, where it continues to stay subscribed, giving cell values that are dynamically updated with live OPC data.
• Individual points, or a selected set of points, can be read or written to.
• Point parameters can be edited before a subscription, read or write is made.
• Multiple points can be easily subscribed to at once, using the "Bulk Add" command.
• The live view can be turned online/offline with a single push of a button.
• Single cell, or any range of cells can be copied to clipboard and pasted to other programs.
• Data can be copied to clipboard either statically, using their current value, or (for Excel) dynamically, using RTD function (see Excel Connector).
• The currently displayed list of points can be saved to an XML file, or retrieved from a file.
• Various connectivity options can be configured, and the configuration can be in turn used when the same data is accessed by Excel.

The Connectivity Explorer uses the Connectivity Model as basis for its operation. Please refer to the Connectivity Model documentation whenever necessary.
