1 The FBXi Series
INTRODUCTION
The FBXi Series is a freely programmable range of BACnet® Controllers with native BACnet/IP
communications support. The controllers are BTL listed (pending) BACnet Building Controller (B-BC) and are
ideally suited for a wide range of applications for intelligent control of HVAC equipment, and electrical
systems including lighting control and metering applications. The FBXi Series supports multi-protocol
communications simultaneously including BACnet/IP, BACnet MS/TP, Modbus® TCP and Modbus RTU.
Part of Cylon’s FLXeon Line of BACnet field controllers, the FBXi Series features support for up to sixteen FLX
(Field Level eXpansion) series extension modules providing up to 256 points of control, and a dedicated input
for Cylon’s CBT-STAT or UCU Room Display intelligent room sensors. FLX I/O expansion modules are available
in a variety of options to allow maximum flexibility in achieving the required point configuration.
FBXi, CBXi and FBVi controllers with Firmware v
9.1.0
and later have additional capabilities over previous ABB
Cylon controllers and are referred to as “Smart Routers”. One of these features is the ability to store the
strategies and configuration for the controller, and also support full upload and download of data for MSTP
fieldbus controllers.
APPLICATION
The FBXi Series is designed for a wide range of energy management applications for intelligent control of:
• HVAC equipment such as Central Plant, Boilers, Chillers, Cooling Towers, Pump Systems, Air Handling
Units (Constant Volume, Variable Air Volume and Multi-zone), and Rooftop Units,
• Electrical systems such as lighting control, variable frequency drives and metering.
The FBXi Series can be used as an integration platform and natively supports the routing of either BACnet
MS/TP to BACnet/IP or Modbus RTU to Modbus TCP without the need for gateways or additional hardware.
The controller accommodates available pre-engineered strategies or can be tailored to custom applications
