Controller Configuration
Controller Type
Various products have the capability of being configured as one of several
possible controller types, which represents the network level that it will reside
on in the network architecture (Area, System, Subnet). Other than the one
controller acting as a router, all other controllers on the same network segment
must be configured the same.
Area -
Configures the controller as an Area level controller on a network. This
is an option only on the Ethernet model and is the setting when the controller is
connected to an Ethernet network (typically between buildings) and is acting as
a router from one LAN to either a network of System controllers or Subnet
controllers.
System
- Configures the controller as a System level controller on a network of
System controllers. This is the setting when the controller is connected to an
Ethernet or BACnet MS/TP network with other System controllers or is a single
head-end controller for a network of Subnet controllers.
Subnet
- Configures the controller as a Subnet level controller on a Subnet of
similar controllers. This is the setting when the controller is connected to a
BACnet MS/TP network with other Subnet controllers.
Note
: This also determines where the DIP or MAC address is mapped into the
controllers BACnet address and which other portions of its BACnet address are
inherited when DNA is enabled.
AREA
SYSTEM
SUBNET
Derived Network Addressing
The
DNA jumper
comes ON by default. This allows the controller to
automatically configure a BACnet controller address. This should NOT be
removed unless you are assigning a BACnet controller number through
software. The BACnet controller number should not be confused with the DIP
switch setting, and each controller must still have a unique dip switch address
even when using software to define the controller number.
DNA
Controller Addressing
The Dip Switch is a binary switch. Each individual DIP switch represents a
unique value, which forms the controller address when added together.
To set the address, simply move the switches that add up to the controllers
desired address to the ON position.
Example: If the controller is to be address 5 on the network, set the switch
numbered 4 and the switch numbered 1 (equals 5) to the On position.
Note
: Each controller on the same MS/TP segment must have a unique DIP
switch address.
