Quick Help
Map
number simply tells you where you're at on the list of object maps.
Click "next" and "prev" to scroll through the list. To advance directly
to a specific map, enter the desired number in the "Map #" box,
then click Update. The
local object data may be written periodically, or when it changes, or
both. To send upon change (send on delta), check the first box and enter
the amount by which the local object must change before being written
to the remote device. To guarantee that the remote object will be
written at least occasionally even if the data does not change, check
the second box and enter some amount of time. This time period will be
referred to as the "maximum quiet time". Data
from the local object may be manipulated before being written to the
remote object. The local data is first multiplied by the scale factor.
The offset is then added to it. For
the remote object to be written, enter the propert number, object
instance and type, index if applicable (leave at 0 if not), and
priority to use of the object being written is commandable. The names in
the device list are defined in the Devices page. The
most commonly written property will be Present Value, which is property
number 85. For other property codes, refer to the BACnet protocol
specification or the User Guide for the Babel Buster Pro V230. The
repeat time may determine how often the remote object will be written.
If send on delta and maximum quiet time are not checked above, clicking
the "at least" button will establish a periodic update time. If
send on delta is used and you wish to limit the network traffic in the
event changes are frequent, click the "no more than" button and
enter the minumum time that should elapse before another write to the
remote device. You
have the option of enabling this map only when a selected object
contains a given value. Any local object may be used as the index
object. As the name implies, you can write different values to the
remote object based on different maps as indexed by the index object. Delete
will remove the map number shown in the "Map #" box. Insert will
insert a new map before the map number shown, and is used for placing
maps between existing maps. It is not necessary to use Insert to add
maps to the bottom of the list or to define any map presently having
zero for a source object or "none" for remote type. Selecting
"none" for remote type effectively deletes the map even though it will
still appear in the list until deleted. Unused maps at the end of the
list will always show none as the type. If you wish to prevent these
from being displayed, reduce the number of maps enabled. The
number of maps enabled simply limits the scope of map review so that
you do not have to review a lot of unused maps. If the displayed maps
are used up and you need more, increase the enabled number. |
