Parameters/fields

If you are unable to write to a parameter or field, make sure that you have the keys to unlock this parameter or field. You must have the Can Configure key to look at locks. Contact your system administrator to find out whether or not you have the Can Configure key. To verify the current user, follow these steps:

  1. Determine the lock on the parameter or field.
  2. Use the DeltaV Explorer to determine which lock protects this parameter or field.
  3. Verify the area that has been assigned to the workstation.
  4. Click Help → About DeltaV Explorer. Look at the Current User panel.

If your name appears in this panel, you are the current user.

If you are not the current user, click Tools → DeltaV Logon and log on. Contact your system administrator if you do not know your user name or password or if you get an error when logging on.

Once you have verified the current user, perform the following steps:

  1. Click Start → DeltaV Engineering → DeltaV Explorer.
  2. In the DeltaV Explorer, expand System Configuration as well as Setup. Then, click Security. In the Contents of Security area of the window, click Parameter Security to look at locks on parameters or Field Security to look at locks on fields.

    The Parameter Security Properties or Field Security Properties dialog opens.

  3. Scroll through the list in the Parameter Security or Field Security dialog, find the parameter or field you want to write to, and make a note of the lock that protects the parameter or field.
  4. Close the dialog.

If you do not have a key to the lock, ask the system administrator to grant you that key for the area assigned to the workstation.

The system administrator uses the following procedure to grant a key to the lock that protects the field or parameter:

  1. Click Start → DeltaV Engineering → User Manager. The DeltaV User Manager program opens.
  2. Double-click the user name to open the Properties For User dialog and click the Keys tab.
  3. Select the lock in the All Locks list, click the Grant Key button to grant that key to the user, and then select the Plant Area for which the user needs the key. That is, the same area as assigned to the workstation.
  4. Click OK.
  5. Return to the DeltaV Explorer to download the runtime database.

You must have the Can Download key to download the runtime database. Contact your system administrator to find out whether or not you have this privilege.

To download the runtime database using the DeltaV Explorer:

  1. Right-click the workstation that you want to download, and then select Download.
  2. Click the first option on the slide-off menu (for example, ProfessionalPLUS workstation).
  3. Follow the prompts to download the workstation.

If you are still unable to download, contact DeltaV Technical Support.
