Just add the following line to the Menu.xml file in openHistorian:
<MenuDataItem Icon="" MenuText="_Concentrator Output Streams" Description="Manage Output Streams" Roles="*" UserControlAssembly="GSF.PhasorProtocols.UI.WPF.dll" UserControlPath="GSF.PhasorProtocols.UI.UserControls.OutputStreamUserControl" />
Concentrated output streams are not openHistorian’s primary function - so this is not turned on by default. Adding that line will allow you to configure an IEEE C37.118 output in openHistorian.
Thanks,
