1.1 How to Use This Guide
The first few sections of this user guide provide background information on how the gateway works, and
an overview of the configuration process. The next several sections are guides for each of the tabs found
in the web interface in the gateway which is accessed by opening a web browser and browsing to the IP
address of the device.
You should at least read the overview sections to gain an understanding of how the gateway functions.
You can use the remaining sections as reference material to look up as needed. There is a "Quick Help"
section at the bottom of each web page in the gateway which is generally sufficient for quick reference in
setting up the gateway.
1.2 Overview of Gateway Devices
The Babel Buster BB2-7010 is a BACnet to Modbus gateway. It may be used as BACnet IP client and
server, Modbus TCP client and server, and Modbus RTU master or slave. The BB2-7010-02 may also be
used as SNMP client and server. The BB2-7010-06, -07, and -08 models add gateway capability for
specific types of WiFi sensors (see section 16, 17, 18).
The most common application for the BB2-7010 is interfacing a Modbus RTU device to a BACnet
IP network. The BB2-7010 will automatically poll the Modbus RTU device, and store the content if its
1. Overview file:///C:/AAA_CSI/Literature/2015 User Guides/BB2-7010/BB2-7010 ...
1 of 2 10/16/2015 12:30 PM

registers in BACnet objects you assign. The BACnet system may then use standard BACnet services such
as Read Property to access the content of the Modbus registers. The BB2-7010 will also accept COV
subscriptions such that other devices will receive a COV notification when the content of a Modbus register
changes.
The BB2-7010 can be also configured as a Modbus RTU slave. This is useful when a PLC wants to write
data to the BB2-7010, thereby making the PLC's data available as BACnet object properties.
The BB2-7010 can be configured as a BACnet IP client. This means the BB2-7010 will be reading and
writing properties in other BACnet devices, storing copies of their object's Present Value in the BB2-7010.
The stored values may later be accessed by Modbus or SNMP.
1.3 Important Safety Notice

Follow these steps to make the initial connection to the BB2-7010.
(a) Connect power. Apply +12 to +24VDC or 24VAC to the terminal marked “POWER”, and common or
ground the the terminal marked “GND”.
(b) Connect a CAT5 cable between the RJ-45 jack on the top and your network switch or hub. You cannot
connect directly to your PC unless you use a “crossover” cable.
(c) Apply power. A blue LED inside the case should light indicating power is present. If the yellow LED on
the RJ45 jack is not on, check your Ethernet cable connections. Both green and yellow LEDs on the RJ45
jack will be on solid for a time during boot-up. The entire bootup process will take 1-2 minutes, during
which time you will not be able to connect with a browser.
(d) The default IP address as shipped is 10.0.0.101. If your PC is not already on the 10.0.0.0 domain, you
will need to add a route on your PC. Do this by opening a command prompt. First type “ipconfig” and note
the IP address listed. This is your PC’s IP address. Now type the command
route add 10.0.0.0 mask 255.255.255.0 1.2.3.4
but substitute your PC’s IP address for 1.2.3.4.
This generally works, but if this fails, you will need to temporarily change your computer’s IP address to a
fixed address that starts with 10.0.0. and ends with anything but 101.

(e) Open your browser, and enter “http://10.0.0.101/” in the address window. You should see a page with
the “Babel Buster BB2-7010” header shown above. From this point, you will find help on each page in the
web site contained within the product.
(f) When you click on any of the page tabs such as System Setup, you will be asked for a user name and
password. The default login is user name “system” with password “admin”. You can also log in as “root”
using password “buster”. You should log in as “root” if you will be changing the IP address.

(g) To can change the IP address of the BB2-7010, go to the Local Host page under System :: Setup. The
following page should appear. Change the IP address, and subnet mask and gateway if applicable. Click
Change IP to save the changes. The process of programming this into Flash takes around half a minute.
The new IP address only takes effect following the next system restart or power cycle.

(h) Most changes are stored in an XML configuration file in the device’s Flash file system. Only a few are
stored differently, and the IP address is one of those. Normally, clicking Update on any configuration page
only stores that configuration information to a temporary RAM copy of the configuration file. To make your
changes other than IP address permanent, you must click Save on the Config File page (System :: Setup
:: Config File).

The BB2-7010 requires only minimal configuration to be useful in its simplest form. First, you must assign
a device instance to the BB2-7010, and you do this via the BACnet IP Port page. You may leave all other
settings at their default. You could leave the device instance at its default as well. The only real
requirement is that you do not duplicate device instances.
The number of each type of available object is indicated here. Initially, there will be only 10 AI's and 1
each of the other object types. There is a pool of objects that may be shared among the different object
types. The number of objects available is displayed at the "System Capacities" link on the home page of

the device. The number will range from 300 to 1000 depending on model.
The number displayed next to the input window is the object count that has been requested and will take
effect upon the next restart. To request a different number, enter that number and click Save. Restart (or
power cycle) the device to make the new object allocations take effect.
The check box for "allow fault self-reset without ack" means object reliability code and fault status will
return to normal automatically after recovery from a communication fault such as "no response" (reply
timed out). If this box is not checked, a BACnet client must read the reliability code to acknowledge the
problem before the status will be reset. If the box is checked, fault indications will simply go away when
the fault goes away.
The check box for "enable BBMD" is used to enable the BBMD feature of the device. When enabled,
additional configuration on the BBMD tab should also be set up.

The BB2-7010 contains a set of BACnet objects whose only purpose is to store copies of data obtained
from other devices. This copy of data may then be queried by different devices, or written to different
devices by the BB2-7010 client functions.
The collection of objects includes Analog, Binary, and Multi-State types of objects, and includes Input,
(commandable) Output, and (writeable) Value types of each of those objects. The BB2-7010 also contains
a Device object which is shared with router functions. All of the remaining objects noted here are not used
by routing functions.
Data may be placed in the local objects by other devices writing to the BB2-7010, or by the BB2-7010
querying other devices. When the BB2-7010 is configured to query other devices, these operations are
defined by “read maps” and “write maps” associated with the respective client function (e.g. BACnet client,
Modbus TCP client, SNMP client).
The following pages illustrate the Analog Input object pages and the Binary Output object pages. The
remaining object pages found in the BB2-7010 are virtually identical, and are not replicated here.
Each object page initially comes up as a table of object data. Click on the object number in the left-hand
column to expand the view of that object and access the windows that let you locall force values, assign
units or names, etc.

The object name, units, value, and status are shown for a list of objects starting with the number entered
at the top of the page. Click Prev/Next to scroll through the list. Click on the object number in the first
column to change name, units, COV, and out-of-service state.
The source of data for an Analog Input object will be reading the remote Modbus register via the map
indicated by the Device Link. The Modbus device will be polled at the rate specified by the Read Map.
Out of Service means polling of the Modbus register will stop. While out of service, the present value may
be written by the BACnet client. Data may be forced via this web page at any time, but will be overwritten
by the next Modbus poll unless the object is out of service.
Reliability codes may be any of the following (7010-01):
64: Modbus client, no response
65: Modbus client, crc error
66: Modbus exception, illegal function code
67: Modbus exception, illegal data address
68: Modbus exception, illegal data value
69-79: Modbus exception, code+65, rarely used
80: Local device, configuration property fault
81: Faulty Modbus packet
82: BACnet IP client, device timeout
83: BACnet IP client, error returned by server

82: BACnet IP client, device timeout
83: BACnet IP client, error returned by server
84: SNMP client, no response from agent
85: SNMP client, unable to parse data
86: SNMP client, reply does not match request
Status flags A,B,C,D indicate the following, 0 meaning not true, 1 meaning true:
A = in alarm
B = fault
C = overridden
D = out of service
Device link will indicate BAC or TCP, followed by R for read or W for write, and a number which is the rule
number in the table of read or write rules for mapping external devices or objects to this BACnet object.
The designation R means read from external device, and W means write to external device.
Click on the AI map number to get to the expanded view of the AI object as illustrated below.
The object name, units, value, and status are shown for the object number entered at the top of the page.
Click Prev/Next to scroll through the list. Click Refresh to update the page, or Update to accept changes.
The object name may be changed here. BACnet units may be selected. Initial COV increment may be
entered. When any of these are changed, be sure to save the updated configuration by clicking Save on
the Config File page under System Setup.
The object may be set Out of Service by checking that box and clicking Update. The present value may be
changed by entering a value, checking Force, and clicking Update.
The source of data for an Analog Input object will be reading the remote Modbus register via the map
indicated by the Device Link. The Modbus device will be polled at the rate specified by the Read Map.

Out of Service means polling of the Modbus register will stop. While out of service, the present value may
be written by the BACnet client. Data may be forced via this web page at any time, but will be overwritten
by the next Modbus poll unless the object is out of service.
The Binary Output Object page is illustrated below.
The object name, value, and status are shown for a list of objects starting with the number entered at the
top of the page. Click Prev/Next to scroll through the list. Click on the object number in the first column to
change name or out-of-service state.
The destination of data for a Binary Output object will be writing the remote Modbus register via the map
indicated by the Device Link. The Modbus device will be updated upon change of source data and/or
periodically as defined by the Write Map.
The Binary Output object is commandable, meaning the BACnet client must write both a value and a
priority level for that value. The highest level value will be the one written to the Modbus register. If all
values are relinquished, the relinquish default value will be written to the Modbus register.
Out of service means the Modbus register will not be written. Values written by the BACnet client will be
retained, but only applied when this object is placed back in service. At that time, the highest priority
value will be written to the Modbus register.
Click on the object number in the left-hand column to get to the expanded view of the Binary Output
object:

The BB2-7010 can be a Modbus RTU master or slave. As a master you can read Modbus data from, or
write Modbus data to, other Modbus slaves. The BB2-7010 will periodically poll the other Modbus devices
according to register maps you set up. To read from a remote Modbus device, configure a Read Map. To
write to a remote Modbus device, configure Write Map.
Data read from a remote device is stored in a local register when received. Data written to a remote
device is taken from a local register when sent. The local registers are the same collection of registers that
are accessible to other masters when operating as slave, and accessible to other Modbus TCP devices as a
collection of holding registers.
5.1 Modbus RTU Device Configuration
Modbus device configuration for RTU really consists of port configuration, and includes setting the slave
address if the BB2-7010 is functioning as Modbus slave.
Select baud rate and parity from the drop down list. Click either Master or Slave buttons to select type of
operation. Enter timing parameters or address as applicable. Click update to register your changes.

IMPORTANT: Set timeout to something long enough for the device. If too short, the gateway will not wait
long enough for a response from the Modbus slave device, and the result will be a lot of "no response"
errors from the device even though the device is perfectly functional.
If your slave/server device only supports function codes 5 and 6 for writing, check the Use FC 5/6 box.
The default function codes are 15 and 16, which are most widely used. If you check the box, you should
also enter a "starting at" unit # or slave address. This allows supporting both types of devices at the same
time provided you assign slave addresses in two non-overlapping groups. (These settings do not apply if
the BB2-7010 is the slave.)
The double register swap on this page only applies when the local device (the gateway you are configuring
here) is functioning as a Modbus RTU slave.
The term "swapped" only applies to double or float formats. Modbus registers are, by definition, 16 bits of
data per register. Access to 32-bit data, either 32-bit integer ("double"), or IEEE 754 floating
point ("float"), is supported by the use of two consecutive registers. Modbus protocol is inherently "big
endian", therefore, Modbus by the Module defaults to having the high order register first for double and
float. If the low order register comes first on the device being accessed, check the "swapped" box.
If you have "swapped" turned around, you will quickly recognize it. If floating point data is reversed, a 1.0
becomes 2.2779508e-41, which simply rounds to zero. The pattern is not as predictable as the 1.0
example would suggest. A floating point 1.1 becomes negative 107609184. If 32-bit integer data is
reversed, 1 becomes 65536.
5.2 Modbus RTU Master Read Maps
Rule number simply tells you where you're at on the list of register maps. Click "next" and "prev" to scroll
through the list. To advance directly to a specific map, enter the desired number in the "Showing" box,
then click Update.

2 of 8 12/8/2015 7:24 PM

Rules entered on this page only read data from remote devices. Go to the RTU Write Map to write data to
those devices. The full parameter set is different for read versus write.
An abbreviated version of a list of rules is shown on this page. Any of the parameters shown may be
changed here and registered by clicking the Update button. To view and/or modify the complete set of
parameters, click on the map number in the left most column.
For each remote register to be read, enter the register type, format, number, and remote unit (slave
address).
When the remote register is read, the data will be multiplied by the scale factor and written to the local
register number given. The name is optional and used only for display purposes.
Selecting "none" for remote type effectively deletes the rule even though it will still appear in the list until
deleted. Unused rules at the end of the list will always show none as the type.
Local register numbers are 1-999 for integer values, and 1001-1999 accessed as register pairs for floating
point. If you try to enter an even number above 1001, you will get an error message. All floating point
register pairs start on odd boundaries. All local registers are accessed via Modbus as holding registers.
Click on the map number in the left column of the tabular read map page (above) to get the expanded
view of one read map at a time (below).
Rule number simply tells you where you're at on the list of register maps. Click "next" and "prev" to scroll
through the list. To advance directly to a specific map, enter the desired number in the "Map #" box, then
click Update.
For each remote register to be read, enter the register type, format, number, and remote unit (slave
address).

When the remote register is read, data may be manipulated before being written to the local register. If a
bit mask is entered (in hexadecimal), and the remote register type is signed or unsigned (16-bit data), the
mask will be bit-wise logical AND-ed with the data, and the retained bits will be right justified in the result.
The result will then be multiplied by the scale factor. The offset is then added and this final result is
written to the local register number given. The name is optional and used only for display purposes.
The periodic poll time determines how often the remote register will be read. This number, if nonzero, will
override the default poll time given in the Devices page for the remote device being read.
The default value will be stored into the local register after the given number of read failures if the fail
count is non-zero. Setting the count to zero will disable the default, and the object will retain the most
recent value obtained.
Delete will remove the rule number shown in the "Map #" box. Insert will insert a new rule before the rule
number shown, and is used for placing rules between existing rules. It is not necessary to use Insert to
add rules to the bottom of the list or to define any rule presently having zero for a source object or
"none" for remote type.
Selecting "none" for remote type effectively deletes the rule even though it will still appear in the list until
deleted. Unused rules at the end of the list will always show none as the type. If you wish to prevent these
from being displayed, reduce the number of rules enabled.
The number of rules enabled simply limits the scope of rule review so that you do not have to review a lot
of unused rules. If the displayed rules are used up and you need more, increase the enabled number.
5.3 Modbus RTU Master Write Maps
Rule number simply tells you where you're at on the list of register maps. Click "next" and "prev" to scroll
through the list. To advance directly to a specific map, enter the desired number in the "Showing" box,
then click Update.
Rules entered on this page only write data to remote devices. Go to the Client Read Map to read data from
those devices. The full parameter set is different for read versus write.
