User accounts on a DeltaV system

DeltaV systems contain user accounts that are built-in, that is, are created when the DeltaV software is installed. These accounts are further classified as service accounts, application accounts, and interactive user accounts based on their purpose.

To minimize security risks, the DeltaV installation disables the accounts that are not necessary for DeltaV out-of-the-box functionality.

To manage accounts, the currently logged on Windows user must be both a Windows administrator (that is, a member of the Windows Administrators group) and a DeltaV administrator (that is, a member of the DeltaV Admins group). When in a domain, you must be a domain administrator to manage the domain user accounts.

DeltaV Security Administration provides the following account management features:

Enable or disable DeltaV built-in Windows application accounts
Change passwords for DeltaV built-in Windows application accounts
Note
If you change the password and the account is used on any other computers (DeltaV or non-DeltaV), you must change the account's password to be the same on all computers where the account exists and is connecting to this DeltaV computer.

If you change the password and the account is used as a service's Log On As account, you must manually change the password for that service and stop and restart the service (or reboot the computer).

Run Windows Services utility and sort the list of services running on the computer by the Log On As column.

Right the service using the account and select Properties.

On the Log On tab, set the new password and leave the dialog open.

On the General tab, click the Stop button.

After the service has stopped, click the Start button.

Click OK.
Disable, enable, or delete DeltaV built-in interactive Windows user accounts
Change passwords for DeltaV built-in interactive Windows user accounts
Create new Windows administrative accounts

Note

Deleting an account deletes the operating system (Windows) account. Delete the DeltaV database user account in DeltaV User Manager (Start → DeltaV Engineering → User Manager).
