Historian Wizard option

Historian options specify the node name of a Historian server or the UNC path to InTouch LGH files that provide historical data shown by a trend.

• AutoDetect: The Historian node name is automatically detected from the AppEngine on which the reference attribute is running. For example, if the Reference field is set to UDO.UDA1, then Auto-Detect is set to the Historian server name configured for the AppEngine on which UDO is running.

• Expression: Set the node name of the Historian server as the value of the HistorianName custom property.

• InTouchLGH: Set the UNC path to the InTouch Log History/LGH file as the value of the UNCPath custom property that will provide the historical data.

• None: No Historian node name is required. The trend shows only current run time data.
