1. 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.

3. Hardware Connections
It is possible to connect a BACnet device to any of the eight RS-2323 ports. These ports just need to be
configured for BACnet in the configuration file.
Configure the PLC (or BCU) according to manufacturer’s instructions

4. 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.
Node_Name Provide name for node Up to 32 alphanumeric characters
Node_ID Node ID of physical server node (the BCU) 1 - 4194303
Protocol Specify protocol used BACnet_PTP
Port Specify port P1-P8
