Description:
The PUB and PVB controllers are part of the Spyder family.
The nine controllers are BACnet MS/TP network devices
designed to control HVAC equipment. These controllers
provide many options and advanced system features that
allow state-of-the-art commercial building control. Each
controller is programmable and configurable using the
NIAGARA FRAMEWORK® software.
The Spyder BACnet controllers require the Spyder BACnet
Programmable Feature to be licensed in the WEBpro
workbench tool and the WEBS AX JACE Controller for
programming and downloading. The Spyder BACnet Models
are also available as Individually Licensed Controllers (ILC).
The ILC versions are identical in design and capability in
every detail except for the licensing. The Individual
Licensing of the Spyder ILCs (the License is built in) allows
them to be programmed and downloaded with any brand of
the Niagara Workbench or JACE controller. The Spyder ILCs
are identified with a suffix on the Part Number of -ILC.
Example: PUB6438S-ILC follows all the same Installation
Instructions information as the PUB6438S.
The controllers are for use in VAV (Variable Air Volume),
Unitary, and advanced HVAC control applications. Each
controller contains a host microcontroller to run the main
HVAC application and a second microcontroller for
BACnet MS/TP network communications. Each controller
Communications
Each controller uses a BACnet MS/TP communications
port. The controller’s data is presented to other controllers
over a twisted-pair MS/TP network, which uses the EIA485
signaling standard capable of the following baud
rates: 9.6, 19.2, 38.4, 76.8, or 115.2 kilobits per second
(configured at global controller). The Spyder BACnet
controllers are master devices on the MS/TP network.
Each Spyder BACnet controller uses a high-quality EIA485
transceiver and exerts 1/4 unit load on the MS/TP
network.
Cabling should be selected that meets or exceeds the
BACnet Standard which specifies the following: an MS/TP
EIA-485 network shall use shielded, twisted-pair cable
with characteristic impedance between 100 and 130
ohms. Distributed capacitance between conductors shall
be less than 100 pF per meter (30 pF per foot). Distributed
capacitance between conductors and shield shall be less
that 200 pF per meter (60 pF per foot). Foil or braided
shields are acceptable. The Honeywell tested and
recommended MS/TP cable is Honeywell Cable 3322 (18
AWG, 1-Pair, Shielded, Low Cap, Plenum cable),
alternatively Honeywell Cable 3251 (22 AWG, 1-Pair,
Shielded, Plenum cable) is available and meets the
BACnet Standard requirements
(www.honeywellcable.com).
The BACnet MS/TP network is polarity sensitive. The
maximum BACnet MS/TP network Bus segment length is
4,000 ft. (1,219 m) using recommended wire. Repeaters
must be used when making runs longer than 4,000 ft.
(1,219 m). A maximum of three repeaters can be used
between any two devices.
