PCS Subscriptions
The Server branch of the Server Status Tool includes a PCS Subscriptions category. This category provides status information about the server-wide PCS Subscriptions that apply to this Geo SCADA Expert server.
NOTE: This category only appears in the Server Status Tool if the suite of PCS prerequisite components are installed on the Geo SCADA Expert server. For more information, (see Geo SCADA Expert Prerequisite Components).
Subscription requests are received through the iData interface in the PCS Service, the PCS Service then subscribes to the Geo SCADA Expert database (see OPC UA Server & PCS Service Settings).
NOTE: An OPC UA client or server can also use the PCS Service to subscribe to database items in the Geo SCADA Expert database.
The PCS Subscriptions category provides information about each subscribed database item:
- Id—Indicates the identifying number of the subscribed Geo SCADA Expert database item.
- Buffered—Indicates whether a subscribed database item is buffered.
- Tag Count—Indicates the number of tags that are subscribed to from the database item (see PCS Tags).
