Application
The FEC16 Field Equipment Controller (FEC) is part of the
Metasys
®
system Field Equipment Controller family.
The FEC16 controller runs pre-engineered and user-programmed applications and provides the inputs and outputs
required to monitor and control a wide variety of HVAC equipment.
The FEC controllers can communicate using either BACnet Master-Slave/Token-Passing (MS/TP) or N2
communications protocols. These controllers used as MS/TP devices operate on an RS-485 BACnet
®
MS/TP Bus
as BACnet Application Specific Controllers (B-ASC) and integrate into Johnson Controls
®
and third-party BACnet
systems.
The FEC16 controller is available with or without an integral LCD and push-button user interface.
Communications Protocol
The
Metasys
®
system FEC Family Controllers and network sensors communicate using either the standard BACnet
protocol, based on the ANSI/ASHRAE 135-2008, or the BACnet/IP protocol. The BACnet protocol is a standard for
ANSI, ASHRAE, and the International Standards Organization (ISO) for building controls.
FEC, VMA16, VMA18, and most IOM field controllers are BTL-listed as BACnet Application Specific Controllers
(B-ASCs). FAC field controllers and the VMA1930 Field Controller are BTL-listed as BACnet Advanced Application
Controllers (B-AACs).
Release 10.1 and later of the Controller Configuration Tool (CCT) can be used to switch the Field Bus communications
protocol in supported FEC, FAC and VMA controllers to be either the standard BACnet MS/TP or the N2 protocol.
All new controllers use either BACnet MS/TP as the default communications protocol, or BACnet/IP. Switchable
communications protocols in the MS/TP models provide a cost-effective upgrade and modernization path for customers
with existing N2 controllers.
