System Tags

System Tags provide status about the Ignition system, such as memory usage, performance metrics, and so on. System Tags cannot be deleted or modified.  In the Tag Browser, under the System folder, there two folders: Client and Gateway. The scope for each is slightly different.

System Tags

System Client Tags for Vision

Client-scoped System Tags provide status information about the client's system.  Every individual client is going to have their own values like IP address, host name, username, and more. You cannot modify Client System Tags. 

 Click here to see the System Client Tags...

There are three folders within the System > Client Tags folder: Network, System, and User. These Tags are provided with Ignition. They can be used with the Vision module for any Vision Client. They cannot be modified.

Gateway System Tags

Gateway System Tags exist in the Gateway scope. There are nine folders within the System > Gateway Tags folder: Alarming, Database, Devices, EAM, Gateway Network, OPC, Performance Redundancy and Sessions.

 Click here to see the System Gateway Tags...

The following Gateway-scoped System Tags are provided with Ignition. They can be used anywhere within Ignition.

TagValueData Type

Clear and AckedNumber of alarms cleared and acknowledged.Integer
Clear and UnackedNumber of alarms cleared and unacknowledged.Integer

Database Folder

There will be a subfolder for each database connection, or none if there are no connections. Each subfolder will have the following Tags.

ActiveConnectionsNumber of active connections in the pool to this database connection.Integer
AvailableIndicates whether this datasource is available.Boolean
AvailableThroughFailoverIndicates if any database along the failover chain attached to this data source can be reached.Boolean
AvgQueryTimeAverage time, in seconds, that it is taking database queries to run.Integer
