with address 0, ending with a device with a configurable Max Master field at the
highest address. Then set that device’s Max Master field to its address. This will
prevent any unnecessary poll for master packets on the network and thereby
maximize efficiency.

BACnet Object Common Configurable Fields
This section describes the common configurable fields for all BACnet objects. For
more information on BACnet object editing options, refer to section 8.6.
Type
The radio buttons in this group select the BACnet object type. Choose from
Analog Input, Analog Output, Analog Value, Binary Input, Binary Output, or
Binary Value.
Object Name
This field is the name of the BACnet object. Enter a string of between 1 and 16
characters in length. All object names must be unique within the gateway.
Instance
This field is the BACnet Object’s instance number. Enter a value between 0 and
4194302 (0x0 – 0x3FFFFE).
Database Addr
This field is the database address where the BACnet object’s present value will
reside. Enter a value between 0 and 4095 (0x0 – 0xFFF).
A note for analog objects
: Depending on the designated Data Type, the
maximum allowable database address is 4095, 4094, or 4092 for 8-bit, 16-bit, or
32-bit sized objects, respectively.
Multiplier
Applies to analog objects only.
This field is the amount that associated network
values are scaled by prior to being stored into the database or after being
retrieved from the database. Upon retrieval from the database, the data is
multiplied by the multiplier to produce a network value. Similarly, the network
values are divided by the multiplier before being stored into the database.
Note that the multiplier, coupled with the data type, imposes range limitations on
the network data value. For example, if the data type is 8-bit and the multiplier is
0.5, then the network data can have values only up to 127 (since 255 is the
maximum value that can be stored in 8 bits).
Units
Applies to analog objects only.
Select the desired units from this dropdown
menu. If the desired units are not available in the dropdown menu, select
