BASremote Master — Versatile Web Appliance

The BASremote Master provides the ultimate in
exibility. It can be used for expansion I/O at remote
locations where an Ethernet connection exists. Its
built-in router and gateway capabilities address
unique integration needs where more than one
communications protocol is involved. It can operate
as a function block programmable controller with its
resident Sedona Framework Virtual Machine. Powered
by a Linux engine, the BASremote Master can operate
as BACnet/IP and Modbus TCP remote I/O, Sedona

Six universal I/O points and two relay outputs can
be congured through resident web pages using
a standard web browser and without the need of a
special programming tool. A 2-wire Modbus serial port
can greatly expand the I/O count with built-in routing to
Modbus TCP clients. If BACnet mapping is preferred,
the unit incorporates a Modbus serial to BACnet/IP
gateway. The BASremote Master also allows you to
install custom web pages so you can view the status of

your system in a convenient manner.
Framework controller, Modbus Serial to Modbus TCP
router, Modbus Serial to BACnet gateway, and Modbus
master to attached Modbus slaves all at the same time.
A 10/100 Mbps Ethernet port allows connection to IP
networks and popular building automation protocols
such as Modbus TCP, BACnet/IP, and Sedona SOX.

Universal I/O

Using web pages, six points can be congured as either inputs or outputs, analog or digital. In addition to being discoverable as
BACnet objects, these same points can be assigned Modbus addresses.

• Analog inputs: 0–10 VDC, 0–20 mA but scalable to 0–5 VDC and 4–20 mA

• Temperature inputs: Type II or Type III thermistors

• Contact closure or Pulse inputs: Free-voltage, 40 Hz maximum

• Analog outputs: 0–10 VDC, 0–20 mA

All eld connectors are removable.

Additional universal I/O can be achieved with the simple

addition of BASremote Expansion modules. The

BASremote PoE has the same capabilities as the

BASremote Master except it is powered over the Ethernet

connection thereby providing a “One Cable Solution”.

Application #1 — BACnet/IP or Modbus TCP Remote I/O

Assume that someone forgot to pull MS/TP twisted-pair
wiring to a distant part of the building or that the
specication calls for only CAT 5 structured wiring
cable, a connection can still be made to the BACnet
network. Since the BASremote Master is BACnet/IP
compliant, a simple 10/100 Mbps Ethernet connection
to the IP infrastructure is all that is needed. If the
BASremote Master is located on a separate subnet
from the other BACnet equipment, the unit can register

as a foreign device with a BACnet/IP Broadcast
Management Device (BBMD) located on another subnet
in order to initiate and receive all BACnet broadcasts. If
the Modbus protocol is of more interest, the
BASremote Master supports Modbus TCP as well. If
more I/O points are required, a BASremote Expansion
module can be connected to the BASremote Master
DN port. Up to three BASremote Expansion modules
can be attached in a daisy-chain wiring fashion.

Application #2 — Modbus Serial to BACnet Gateway for Unifying Data

Although BACnet is quite popular, there is an
abundance of Modbus Serial equipment that needs to
attach to the building automation system. There are
two approaches to the problem. The rst is to route
Modbus Serial messages from the BASremote Master
MB port to Modbus TCP clients residing on Ethernet.
This is the simplest approach requiring minimal
conguration. The BASremote Master would act as a
proxy for a Modbus TCP client, initiating a command to
a connected Modbus Serial slave. When the slave
responds, the message is forwarded to the Modbus

Modbus

Power

Meter

TCP client. The resident BASremote Master I/O can
be queried in a similar fashion.

The second approach is to utilize the gateway
capability within the BASremote Master. Using an
off-line spreadsheet, Modbus registers and slave
addresses are mapped along side BACnet object
instances. The spreadsheet creates a CSV le which
is downloaded into the BASremote Master for periodic
scanning. The result is that attached Modbus Serial
devices can be viewed as BACnet objects.

Application #3 — Certied Sedona Framework for Implementing Control

The BASremote Master incorporates Sedona Virtual
Machine (SVM) technology developed by Tridium and
compatible with their Niagara Framework™. Using
established Tridium tools such as Workbench, a system
integrator can develop a control application using
Workbench’s powerful drag-and-drop visual
programming methodology. Once developed, the

Tridium’s Niagara Workbench or a similar tool

can be used to program Sedona running in the BASremote.

program remains stored in the BASremote Master and
executes by way of the SVM. The application can run
standalone in the BASremote Master or interact with a
program in a Tridium JACE supervisory controller over
Ethernet. The number of potential applications is only
limited by the imagination of the system integrator.

The BASremote’s Sedona Framework

logic can operate on its own I/O as well

as that of connected Modbus Serial or

TCP devices. Also, a network connected

Niagara Framework device can read or

modify the operating state of the Sedona

Framework function blocks.

Application #4 — Energy Usage Sub-metering

The BASremote Master can be used as a data
concentrator for sub-metering applications. With
sub-metering, tenants can be billed a portion of the
actual energy usage based upon individual usage.
Sub-metering can also verify actual energy savings
from “green” initiatives. Usually a pulse is generated
from natural gas, water, or electrical meters which need
to be captured and accumulated in order to determine
energy usage. One pulse represents a unit of energy
usually requiring a scaling factor to be applied. The
BASremote Master can be congured through web
pages to handle up to six pulse inputs with independent
threshold settings in order to adapt to different styles of
meters. For convenience, both pulse rate (power) and
accumulation (energy) can be displayed on a
BASremote Master web page after applying a
meaningful scaling factor to the raw data. Sedona

Framework can also be used to calculate beyond simple
scaling. Internally, pulses are accumulated indenitely
until reset by a supervisory controller or through a
protected web page. Pulse data cannot be lost due to
inadvertent power loss because it is stored in nonvolatile
memory. If special energy demand monitoring is required,
this can be accomplished using a Sedona Framework
program in the BASremote Master or with a program in a
supervisory controller.

The more sophisticated electrical meters have a
Modbus Serial interface which can be attached to the
BASremote Master MB port. Using either the router or
gateway functionality of the BASremote, energy usage
data can be presented to a supervisory controller over
Ethernet.

Application #5 — Power over Ethernet (PoE) for a “One Cable Solution”

The Power over Ethernet standard (IEEE 802.3af) gives
the system integrator another opportunity to be
imaginative. With PoE, both 48 VDC power and Ethernet
communication reside on the same cable. PoE power is
derived from Power Sourcing Equipment (PSE). This
could be an Ethernet switch, a multi-port mid-span PSE,
or a single-port PSE commonly referred to as a Power
Injector. Regardless of the PSE, the BASremote PoE
performs the duties of a Powered Device (PD) in that it

Simply make a connection from a

PoE compliant device to the

Ethernet port on the BASremote

One-Cable Solution

Data & Power on One Cable

Power Over Ethernet

can still communicate over Ethernet while powering its
own electronics plus any devices connected to its auxiliary
24 VDC power supply. The BASremote PoE has identical
capabilities as the BASremote Master but without the
need for a power input connection. By using an
uninterruptable power supply (UPS) at the PSE source, it
is possible to guard the BASremote PoE against any
power failures. This arrangement could be attractive in
critical control or security applications.

BASremote Master PoE

Both the BASremote and

eld devices can be

powered from the data cable

Saves from purchasing proprietary
BAS cabling and the associated cost of
installation. May gain you points toward

“green certication”.

Application Guide — BASremote

The new trending feature will allow the trending of the
BASremote’s 8 channels, any connected expansion
unit’s channels and those of any mapped Modbus
devices (RTU or Modbus TCP). The trend data will be
stored within the BASremote. You can select the
frequency of trending and the frequency of storage.

Trending

After the trend le is lled, it will discard the oldest trend
data. The trend data is available via the BASremote
webpage in a simple CSV format. The BASremote can
store up to about 150,000 entries. The trend feature
also supports an NTP feature for accurately setting the
time within the trend.
