Current Server

Associated with: OPC UA Subscription items

This status attribute indicates the name of the OPC UA Server that the OPC UA Subscription is currently using. This status attribute can prove useful with a multiple OPC UA server configuration, to determine which OPC UA server is currently in use. The OPC UA server that is listed will be one of those that is specified on the configuration Form of the OPC UA Subscription item (see Configure the Server and Publishing Properties).

With a multiple OPC UA server configuration, in addition to automatic switching, users with the relevant security permissions can use the Switch Server pick action to manually switch the subscription over to use another OPC UA Server if required. (Unless the Disable Switching pick action has been used to temporarily prevent such switching.)
