Disable Subscription
Associated with: OPC UA Subscription items
Security permission required to access this pick action: Disable Points
NOTE: The 'Disable...' series of pick actions are assigned the 'Disable Points' security permission so that users with that permission can disable database items without necessarily being given the full 'Configuration' security permission. A user, such as an operator, whose User Account is given the 'Disable Points' permission but not the 'Configure' permission can disable a database item, but is prevented from altering the rest of that item's configuration.
Use this pick action to take an OPC UA Subscription database item Out of Service.
The Disable Subscription pick action clears the Subscription's In Service property, so that the Subscription is no longer active.
You might want to disable a Subscription database item, for example, if Geo SCADA Expert has detected a problem with the subscription that the database item represents, or the node to which the subscription relates. Once the problem has been rectified, use the Enable Subscription pick action to place the Subscription back In Service.
Geo SCADA Expert logs an entry in the Event Journal whenever either pick action is used. The entry indicates whether the Subscription has been enabled or disabled.
Be aware that disabling an OPC UA Subscription also de-activates its dependants, although their configuration will remain unchanged. Dependants include items such as points that are associated with the Subscription.
If using this pick action with the Automation Interface, you need to specify the method name Disable.
