Overview – OPC Unified Architecture

8.4.1.1 Overview

The SoftwareUpdateType defines an AddIn which can be used to extend Objects with software update features. All software update options are exposed as references of this AddIn. This way a Client can check for the references of the AddIn to determine which options are provided by a Server. If an option is available, it shall be used as specified.

The SoftwareUpdateType is illustrated in Figure 42 and formally described in Table 76.
