Alarms not able to ACK & Trends not working

Hi
I'm a new ignition scada user , I'm trying to create Trends in Easy chart its working in Ignition designer and not working at VISION Client Viewer, its showing current user doesn't have the requested roles and same for Ack also I'm not able to do just showing error popup.



Pretty common problem when using legacy database tools (DB pens in EasyChart) when you haven't enabled Legacy DB permissions in the project properties.

Ideally, you would use tag historian pens on the easy chart, possibly with the wide table pseudo-historian provider. Elsewhere, you'd use parameterized Named Queries instead of regular query bindings or scripted queries.

Hi pturmel thanks for your replay
here im using tag historian pens on chart and its properly working in designer and im able to take tag history also but in vision client only im unable to trend its showing some user dont have access like that error at log viewer.



Open the project properties from the menu in the designer. Look for and enable Legacy DB Permissions in security. For DB pens.

For tag historian pens, you need to look at the security roles you've attached to the tag provider and/or history provider.
