System Configuration Tables

All AVEVA Historian parameters are stored in system configuration tables. Parameters include information regarding the historian's physical nodes, site-specific configuration parameters, and parameters pertaining to the physical I/O equipment to which the system is connected.

The system configuration tables are:

• _IODriver

• _IOServer

• _Tag

• _Topic

• ConfigStatusPending *

• ConfigStatusSnapshot*

• ErrorLog

• IOServerType

• LocalizedText*

• OPCQualityMap

• SnapshotDetail

• StorageLocation

• StorageShard

• SystemParameter

• TimeZone*

• UserDetail

* System-level table. Do not edit.

Note: The _IODriver, _IOServer, _Tag, and _Topic tables replace the previous IODriver, IOServer, Tag, and Topic tables. New views named IODriver, IOServer, Tag, and Topic now provide backward-compatibly.
