Adapter for OPC connects to a OPC UA server at runtime. You create one or more connections at design-time to use in integrations. The number of connections you create, and the types of those connections, depend on the types of security and security level your integration needs. For example, you can create connection without any security policy or security level with None.

Adapter for OPC connections contain parameters that Integration Server uses to manage connections to the OPC UA server so that they can be used by the adapter to provide services. You configure connections using Integration Server Administrator. You must have Integration Server Administrator privileges to access Adapter for OPC's administrative screens.

For instructions on configuring, viewing, editing, enabling, and disabling Adapter for OPC connections, see Overview of Adapter Connections. For information about setting user privileges, see the webMethods Integration Server Administrator’s Guide.
