Log on and off controls

The controls can use AVEVA OMI or InTouch security to authenticate a run time operator when both OMI/InTouch and MES are using OS security.

The controls are designed to handle the different security settings for the MES system and the OMI and InTouch systems. If OMI or InTouch security is used and the users have been synchronized with MES, the controls will use OMI or InTouch security to authenticate the OMI or InTouch user as an MES user. Otherwise, the control will prompt for user credentials or use the configured user settings on the control.

Note: Any fixed user settings for a .NET control should be a user with minimal privileges, especially when using MES OS User credentials.
