1.2.6 Elevator Reports Events
When you have set up at least one door as an elevator, the elevator reports events fields allow an
operator to filter out redundant elevator related events. This is due to the mechanism used to provide
elevator control, where one reader is shared by the controllers at every elevator door on every floor.
For example, eight controllers with eight elevator doors are wired to the one reader. The lock outputs for
the eight controllers are connected to the elevator control hardware. A user presents a card to the reader.
All eight controllers read the card and either allow or deny access depending on the user’s access rights.
If four controllers allow access and four controllers deny access, four “Access Granted” and four
“Access Denied” messages are generated. This creates a lot of message traffic and takes up a lot of
controller buffer space.
By using the elevator reports events field, you can disable these redundant messages only for those
controllers configured for elevator control. The default is for all elevator control generated events to be
stored and reported in the controller’s event buffer.
NOTE: When a card is presented to a controller that is not recognized by the controller, the controller
records an Unknown Key event message to the controller’s event buffer. When the event buffer is
downloaded to the host computer, the Doors program reviews the list of Unknown Key events and
compares the card ID numbers to the user list. Any Unknown Key messages associated with card IDs
that are in the user list are converted to Access Denied messages. This differentiates between cards that
are truly “unknown” to the system from cards being presented by a user in an attempt to access an area
in which the user is not allowed. In the elevator application, these event messages will be repeated by
all controllers in the elevator network that do not recognize the card.
In this example, the message text string for “Access Denied” is disabled so it will not be stored and
reported in the controller’s event buffer.
1. To access the message text strings, click on the Setup ⇒ Monitor and Events pull-down menu.
2. Click on the Messages tab. The Messages window appears (see Figure 5-10).

3. Locate the “Access Denied” message text.
4. Scan across the row to the “Elevator Reports Event” column and click in the cell. It will change
from an button to an button.
5. The messages tab window should look similar to Figure 5-11 on page 24 of this section.
