4. Configuring the FieldServer as a BACnet IP Client

For a detailed discussion on FieldServer configuration, please refer to the FieldServer Configuration
Manual. The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer (See “.csv” sample files provided with the FieldServer).

This section documents and describes the parameters necessary for configuring the FieldServer to
communicate with a BACnet/IP Server.

4.1. Data Arrays/Descriptors

The configuration file tells the FieldServer about its interfaces, and the routing of data required. In
order to enable the FieldServer for BACnet/IP communications, the driver independent FieldServer
buffers need to be declared in the “Data Arrays” section, the destination device addresses need to be
declared in the “Client Side Nodes” section, and the data required from the Servers needs to be
mapped in the “Client Side Map Descriptors” section. Details on how to do this can be found below.

Note that in the tables, * indicates an optional parameter, with the bold legal value being the default.

Appendix B. Advanced Topics

Appendix B.1. BACnet object names

When an external BACnet Client builds a list of Object Names, the BACnet Server Map Descriptor
names determine the BACnet Object Name. If the Map Descriptor length is greater than 1, the Object
Name will be suffixed with the index into the Map Descriptor. For example, if the Map Descriptor
name is SMD_AI_01 and the length 3, then the Object Names will be SMD_AI_01[0], SMD_AI_01[1]
and SMD_AI_01[2].

Appendix B.2. BACnet Priority Arrays

FieldServer implementation of BACnet priority Arrays

When BACnet Output objects are written to the Server side of the FieldServer, an associated write
priority is given to each write value. When the FieldServer receives the write value, it stores it to the
Map Descriptor Priority Array Table at the specified priority. The Priority Array Table is then scanned
and the value with the highest priority is stored to the Data Array location specified by the Map
Descriptor.

When a Write “Relinquished” command is received, the value is removed from the Priority Array
Table and the next highest value from the Priority Array Table is stored to the Data Array.

If all values have been “Relinquished” from the Priority Array Table, then the Map Descriptors
“Relinquish Default” value will be stored to the Data Array.

Accessing Priority Array information

The Priority Array table and its “In_Use” (or Not Relinquished) state are stored internally to every Map
Descriptor, and cannot be accessed directly. If the following data arrays are specified, however, they
will maintain an exact copy of the Priority Array Table for the Map Descriptor. Thus the Priority Array
Table can be accessed.

will be stored. Location 0 is the Relinquish Default
value and locations 1 to 16 the different entries of the
Priority Array Table.

Name of Data Array that indicates if a particular
Priority Value is in use. Location 0 indicates whether
the Relinquish Default has been set and locations 1

Appendix B.3. Limitations of the BACnet Read_Property_Multiple service.

The BACnet PTP client driver can read multiple BACnet objects using the Read_Property_Multiple
service under the following conditions:

• The number of objects to be read must not exceed 29.

• No gaps must exist in the range of object to be read.

• The Map Descriptor function must be of the Read type. (e.g. Rdbc)

FieldServer Technologies 1991 Tarob Court Milpitas, California 95035 USA Web: www.fieldserver.com

Tel: [phone] Fax: [phone] Toll Free: [phone] email: [e-mail]

FS-8704-06 BACnet IP Driver Manual Page 15 of 24

• The Map Descriptor property must be Present_Value.

Appendix B.4. IP Address Issues related to BACnet IP

It is not necessary to configure the IP address of the Server node in the Client Side Node Descriptor
in the configuration file since the BACnet Client will automatically discover the IP address based on
the Node_ID supplied. It is still necessary for the FieldServer itself to have a valid IP address,
however. Please refer to the FieldServer Utilities Manual for instructions on changing the FieldServer
IP address.

Appendix B.5. Network number

The default Network number of a FieldServer is 5. In order to ensure communication between the
BACnet Client and all Servers on a BACnet network, however, it may be necessary to assign a
unique network number to each FieldServer.

A unique network number will need to be assigned if both of the following conditions are true:

• The FieldServer has multiple BACnet Server nodes.

• There is more than one FieldServer on a network which includes multiple BACnet nodes.

To override the FieldServer’s default network number 5, refer to Section 5.1

Appendix B.6. Using BBMD

BACnet/IP requires that a BBMD be defined on every subnet for cross-router communications. The
FieldServer can act as a BBMD for the subnet that it resides on. Setting the Connection_Type to
BBMD will enable this functionality on the FieldServer. Note that BBMD operation is not required if
there is already another BBMD on the network.

Setting up a Broadcast Distribution Table (BDT)

The FieldServer supports two methods of updating its internal broadcast distribution table.

• Trane’s Tracer Summit IP Validation utility can be used directly to upload and download a
Broadcast Distribution Table.

• The Broadcast Distribution Table can be configured using the bdt.ini file. The following file must
be created and downloaded to the FieldServer using the Ruinet “Download Configuration”
command.

BBMD Configuration Example

Using the following configuration, a PC using BACnet explorer is able to browse and display the
contents of two FieldServers. The following image shows the BACnet explorer screen.

The following diagram shows the layout of the connections between the FieldServers and the PC via
a router.

Appendix C. Troubleshooting Tips

Appendix C.1. Debugging a BACnet connection

• If duplicate object instances are accidentally configured in the FieldServer, the second call of the
instance will overwrite the first one. This may cause a BACnet Object to be “lost.”

• If “Virtual_BCU_…” is not being indicated as the device description for the FieldServer on the
BACnet SCADA system, then the FieldServer is not communicating with the SCADA system. If
the Present_Value’s name is being indicated, but the Present_Value shows question marks, then
it is most likely that the Client side of the FieldServer is not communicating.

• Polling BACnet addresses that are not configured for Liebert systems may cause the connection
to fail in older versions of Liebert. Please contact your Liebert supplier for more information.

• Some of the BACnet IP features result in the creation of files (priarray.ini; desc.ini; alarms.ini) on
the FieldServer. Sometimes updates of firmware can result in these files becoming outdated.
Deleting these files will restore configuration defaults and may assist with configuration errors.

• Extra memory is required to store Map Descriptors that have the active/inactive text parameters
specified. If the defaults are appropriate, do not specify these parameters. This will save
memory and allow more Map Descriptors to be created

• McQuay Units are shipped with a default Device instance of the last 6 digits of the McQuay
Serial number.

Trane Specific Tips

• When new points are added to the FieldServer it is important to restart Summit Workstation or
BCU, otherwise these new points may not be seen by the FieldServer.

• Disconnect the FieldServer from the BACnet network when transferring images to the BCU.

Appendix C.2. BACnet Specific Statistics

Stat Description Resolution

It is normal to receive a few link control
messages. If the number is higher than the
transmit/receive messages, however, there
may be a problem with lost
communications..
This is not an error. BACnet clients often
poll all properties of a particular object to
determine which properties are supported.

This is not an error - the BACnet client will
use a different method to read data from
the FieldServer.

You should not see this message. It
normally indicates a configuration error.
This typically happens when trying to write
to an Input Object that is not Out-Of­Service. It is not possible to write to Input
Objects.
This may be a problem on the Client
system. Consult the PIC statement to
determine what services are supported.

Errors

A “who-is” link control message
was send or received.

A request for an unsupported
property was received

Data was requested but the
response would have exceeded the
maximum size of the APDU and
could not be sent using an un­segmented message.
Invoke ID of a reply did not match
the Invoke ID of the poll.

A write to an object was denied.

A BACnet Service was denied
because it is not supported
