Do not use the software to control time-critical functions.
Do not use the software to control remote equipment without proper access control and status feedback.

Each control object in your user diagram is configured to perform a single function. When you click a control object, it performs the specified function. For example, you could click a control object to clear an energy accumulator, toggle a relay, reset a counter, or adjust the value of an analog output device.

The default appearance of a control object depends on the function it has been configured to perform:

Boolean Pulse Numeric

Regardless of their appearance, all control objects are used the same way—to use a control object, click it.

NOTE: For information on configuring the message, appearance and access level of control objects, see Customizing the action for a control object and Customizing the display of a control object.

When you click on a control object, one of the following happens, depending on how the control object is configured:

  • Vista performs the specified action immediately.
  • Vista displays a confirmation message. Click Yes to proceed or No to cancel the operation.
  • Vista requests a password. Type the logon password then click OK to proceed.

Depending on the function, a dialog prompting for the meter password may also open. If so, type the meter password then click OK to proceed.

NOTE: There can be a time delay until Vista displays a new control value or state after it has been written to the device.
