BACnet Description
The BACnet PTP driver allows the FieldServer to transfer data to and from devices using the BACnet
protocol over a serial RS-232 physical layer. The FieldServer can emulate either a Server or Client.
The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer.

It is possible to connect a BACnet device to any of the eight RS-232 ports. These ports just need to be
configured for BACnet in the configuration file.

Configuring the FieldServer as a BACnet Client
For a detailed discussion on FieldServer configuration, please refer to the FieldServer Instruction 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 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 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.

BACnet Object Names
When an external BACnet Client builds a list of Object Names, the BACnet Server Map Descriptor
name determines the BACnet Object Name. If the Map Descriptor length is greater than 1, then 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 will be stored 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.

Limitations of the BACnet READ_PROPERTY_MULTIPLE service.
The BACnet PTP client driver can read multiple BACnet
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)
• The Map Descriptor property must be Present Value.

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

Debugging a BACnet connection – Hints and Tips
Disconnect the FieldServer from the BACnet network when transferring images to the BCU.
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.
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 configured for Lieberts systems may cause the
connection to fail in older versions of Lieberts. Please contact your Lieberts supplier for
more information.
When a BACnet_PTP connection is established, and the connection is broken abruptly
(for instance a power down), the BCU might not know immediately that this happened. If
the FieldServer is the powered up again, it might take several seconds (up to 60
seconds) before polling will start again.
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

Resolution
It is normal to receive a few link control
messages. If the number is higher than
the transmit/receive messages, 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.
