Alarm Subscriptions

An alarm subscription defines a connection to an alarm server. It is possible for a server to have more than one subscription. In fact, it is a very effective way to achieve filtering. The Alarm Subscriptions tree control in the Unified Data Manager enables you to set up subscriptions to OPC UA AE and legacy Alarm & Events servers. Within the Unified Data Manager you can manage the following aspects of alarm subscriptions:

Create and edit alarm subscriptions.
Create folders for alarm subscriptions.
Provides global management of alarm subscriptions.
Choose between local or global alarm subscriptions.
