1. BACnet IP Description

The BACnet/IP driver allows the FieldServer to transfer data to and from devices over Ethernet using
BACnet/IP protocol. 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.

2. Driver Scope of Supply

2.1. Supplied by FieldServer Technologies for this driver

FieldServer Technologies
PART #

FS-8915-10 UTP cable (7 foot) for Ethernet connection1

Description

2.2. Provided by the Supplier of 3rd Party Equipment

2.2.1. Hardware

Part # Description

Ethernet 10/100 BaseT hub2

1

This cable is necessary for connection to the driver. It is shipped with the FieldServer and not

separately with the driver.

2

Not all FieldServer models support 100BaseT. Consult the appropriate instruction manual for details of

the Ethernet speed supported by specific hardware.

3. Hardware Connections

It is possible to connect a BACnet/IP device using the N1 or the N23 network ports. These ports need to
be configured for BACnet/IP in the configuration file.

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.
