Connecting to a IP network
BACnet IP VAV controller communicates over IP V4
network using:
1.
Wired - Using Ethernet connection via either port.
2.
Wireless
*
- Using integrated Wi-Fi support and optional external
antennae.
* Wireless functionality is for future use.
Controller will search for a DHCP server to acquire an IP address
for 15 seconds after powering ON. If DHCP server is not found,
controller will switch to Auto IP mode. In Auto IP mode
controller will follow Link Local Addressing for Address
Resolution and will acquire an IP address in range 169.254.1.0 -
169.254.254.254.
Network Topologies
—
Recommended cable: Cat5/Cat6
—
Maximum distance between 2 controllers or controller and
switch should be less than 328 ft. (100 meters)
Non-Failover (Daisy Chain)
In non-failover, that is daisy chain connection type, if any of the
device in the network fails, the devices next to the failed device
also fail.
For example, there are 10 devices in a network and device
number 1 is the master device, which connected to device 2,
and device 2 is connected to 3, and so on. If device 5 fails to
function, the device after 5, that is 6, 7, 8, 9, and 10 also fail to
communicate with master device.
Maximum number of controller that can be connected in a
daisy chain is 200.
Daisy Chain Topology (maximum 200 controllers)
Static IP Configuration
Static IP address can be configured using Niagara
workbench.
1.
Navigate to IP configuration under IP settings.
2.
Select the IP address as
Static.
3.
Select Enabled as True.
4.
Configure a valid IP address.
Figure 13. Static IP Configuration
Refer IRM Engineering Tool User Guide - 31-00282 for more
information on how to do this.

Spanning Tree Protocol (RSTP)
If the BACnet IP VAV controllers are to be connected in a
redundant ring, then you must have one spanning tree protocol
supported Ethernet switch as a part of the ring. BACNET IPVAV
supports Ethernet switch for 10/100 Mbps IP connection.
The switch will connect BACnet IP VAV ring with the backbone
network.The loop-free topology ensures that there is no
broadcast storms and duplicate frame transmission. Maximum
number of controllers that can be connected in STP loop is 40.
The connection of a loop managed by a switch.

NOTE:
Controller will use last 2 characters of its Serial Number
as last octet for starting address search.
