The Historian Namespace exposes properties and methods from the .NET objects used by the Historian Module execution. You can use these properties and methods on your Displays or to create Scripts and Alarms.
Below you find a table describing the most used properties from the Historian Namespace. Access the Historian Namespace page for a complete list of available options.
Property | Type | Description | Property path on CodeBehind |
|---|---|---|---|
| Boolean | Indicates the operational status Module Historian has started. When true, the Module Historian actively archives data. When false, no data archiving occurs. |

| String | Indicates the success or failure when initiating the Module Historian. If the Module Historian starts successfully, the system returns an OK string. The system provides a descriptive error message in case of failure during the initiation process to help you diagnose and troubleshoot the issue. |
