1. BACnet Description
The BACnet PTP driver allows the FieldServer to transfer data to and from devi es using the BACnet
proto ol over a serial RS-232 physi al layer. The FieldServer an emulate either a Server or Client.
The information that follows des ribes how to expand upon the fa tory defaults provided in the
onfiguration files in luded with the FieldServer.

4. Configuring the FieldServer as a BACnet Client
For a detailed dis ussion on FieldServer onfiguration, please refer to the FieldServer Instru tion Manual.
The information that follows des ribes how to expand upon the fa tory defaults provided in the
onfiguration files in luded with the FieldServer (See “. sv” sample files provided with the FieldServer).
This se tion do uments and des ribes the parameters ne essary for onfiguring the FieldServer to
ommuni ate with a BACnet Server.
4.1. Data Arrays/ Descriptors
The onfiguration file tells the FieldServer about its interfa es, and the routing of data required. In
order to enable the FieldServer for BACnet ommuni ations, the driver independent FieldServer
buffers need to be de lared in the “Data Arrays” se tion, the destination devi e addresses need to be
de lared in the “Client Side Nodes” se tion, and the data required from the servers needs to be
mapped in the “Client Side Map Des riptors” se tion. Details on how to do this an be found below.
Note that in the tables, * indi ates an optional parameter, with the bold legal value being the default.

Appendix B. Advanced Topics
Appendix B.1. BACnet Ob ect Names
When an external BACnet Client builds a list of Obje t Names, the BACnet Server Map Des riptor
name determines the BACnet Obje t Name. If the Map Des riptor length is greater than 1, then the
Obje t Name will be suffixed with the index into the Map Des riptor. For example, if the Map
Des riptor name is SMD_AI_01 and the length 3, then the Obje t 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 obje ts are written to the Server side of the FieldServer, an asso iated write
priority is given to ea h write value. When the FieldServer re eives the write value, it will be stored to
the Map Des riptor Priority Array Table at the spe ified priority. The Priority Array Table is then
s anned and the value with the highest priority is stored to the Data Array lo ation spe ified by the
Map Des riptor.
When a Write “Relinquished” ommand is re eived, 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 Des riptors
“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
Des riptor, and annot be a essed dire tly. If the following data arrays are spe ified, however, they
will maintain an exa t opy of the Priority Array Table for the Map Des riptor. Thus the Priority Array
Table an be a essed.

Appendix B.3. Limitations of the BACnet READ_PROPERTY_MULTIPLE service.
The BACnet PTP lient driver an read multiple BACnet obje ts using the
READ_PROPERTY_MULTIPLE servi e under the following onditions:
• The number of obje ts to be read must not ex eed 29.
• No gaps must exist in the range of obje t to be read.
• The Map Des riptor fun tion must be of the READ type. (e.g. RDBC)
• The Map Des riptor property must be Present Value.

Appendix B.4. Network number
The default Network number of a FieldServer is 5. In order to ensure ommuni ation between the
BACnet Client and all Servers on a BACnet network, however, it may be ne essary to assign a
unique network number to ea h FieldServer.
A unique network number will need to be assigned if both of the following onditions are true:
• The FieldServer has multiple BACnet Server nodes.
• There is more than one FieldServer on a network whi h in ludes multiple BACnet nodes.
To override the FieldServer’s default network number 5, refer to Se tion 5.1

Appendix C. Trou leshooting Tips
Appendix C.1. Debugging a BACnet connection – Hints and Tips
• Dis onne t the FieldServer from the BACnet network when transferring images to the BCU.
• If dupli ate obje t instan es are a identally onfigured in the FieldServer, the se ond all of
the instan e will overwrite the first one. This may ause a BACnet Obje t to be “lost.”
• If “Virtual_BCU_…” is not being indi ated as the devi e des ription for the FieldServer on the
BACnet SCADA system, then the FieldServer is not ommuni ating with the SCADA system.
If the present value’s name is being indi ated, but the present value shows question marks,
then it is most likely that the Client side of the FieldServer is not ommuni ating.
• When new points are added to the FieldServer it is important to restart the Summit
Workstation or BCU, otherwise these new points may not be seen by the FieldServer.
• Polling BACnet addresses that are not onfigured for Lieberts systems may ause the
onne tion to fail in older versions of Lieberts. Please onta t your Lieberts supplier for
more information.
• When a BACnet_PTP onne tion is established, and the onne tion is broken abruptly
(for instan e a power down), the BCU might not know immediately that this happened. If
the FieldServer is the powered up again, it might take several se onds (up to 60
se onds) before polling will start again.
• Extra memory is required to store Map Des riptors that have the a tive/ina tive text
parameters spe ified. If the defaults are appropriate, do not spe ify these parameters.
This will save memory and allow more Map Des riptors to be reated
• McQuay Units are shipped with a default Devi e instan e of the last 6 digits of the M Quay
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.
• Dis onne t the FieldServer from the BACnet network when transferring images to the BCU
Appendix C.2. BACnet Specific Statistics
Stat Description Resolution
Link Control A who-is link ontrol message was
send or re eived.
It is normal to re eive a few link ontrol
messages. If the number is higher than
the transmit/re eive messages, there may
be a problem with lost ommuni ations.
Unsupported
Properties
A request for an unsupported
property was re eived.
This is not an error. BACnet lients often
poll all properties of a parti ular obje t to
determine whi h properties are supported.
Segmentation
Not Supported
Data was requested but the
response would have ex eeded the
maximum size of the APDU and
ould not be sent using an un-
segmented message.
This is not an error - the BACnet lient will
use a different method to read data from
the FieldServer.
Sequen e Error Invoke ID of a reply did not mat h
the Invoke ID of the poll.
You should not see this message. It
normally indi ates a onfiguration error.
Write A ess
Denied Writing to an obje t was denied.
This typi ally happens when trying to write
to an Input Obje t that is not Out-Of-
Servi e. It is not possible to write to Input
Obje ts.
Ex eption
Errors
A BACnet Servi e was denied
be ause it is not supported
This may be a problem on the Client
system. Consult the PIC statement to
determine what servi es are supported.
