Application
The FX-PCG16 controller is part of the Facility Explorer
Controller FX-PCG family. The FX-PCG16 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 FX-PCG controllers operate on an RS-485 BACnet
®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASC) and integrate
into Johnson Controls
®
and third-party BACnet systems.
With Release 10.1, you can use the FX-PCT software
to switch the FX-PCG to use the N2 protocol.
The FX-PCG16 controller is available with or without an
integral LCD and push button user interface.
Switchable Communications
Protocols
By default, the FX-PC family controllers and network
sensors communicate using the standard
BACnet
protocol, based on the ANSI/ASHRAE 135-2004.
The BACnet protocol is a standard for ANSI, ASHRAE,
and the International Standards Organization (ISO) for
building controls.
FX-PCG, FX-PCX, and FX-PCV controllers are BTL-
tested and listed as BACnet Application Specific
Controllers (B-ASCs). FX-PCA field controllers are
BTL-listed as BACnet Advanced Application Controllers
(B-AACs). The NS Series Sensors are BTL-listed as
BACnet Smart Sensors (B-SSs).
Release 10.1 of FX-PCT and later can be used to switch
the Field Bus communications protocol in FX-PC
Controllers to be either the standard BACnet
Master-Slave/Token-Passing (MS/TP) or the N2 protocol.
BACnet MS/TP is the default communications protocol
for all new controllers. Switchable communications
protocols provide a cost-effective upgrade and
modernization path for customers with existing N2
controllers. The
Modernization Guide for Legacy N2
Controllers (LIT-12012045)
and the controller-specific
documentation provide installation and commissioning
support and include tips for efficient and safe
replacement. Refer to the
N2 Compatibility Options
chapter of the
Controller Tool Help (LIT-12011147)
for
information about mapping N2 Objects in controllers with
switchable communications protocols.
The N2-capable FX-PC controllers can be used as
functional replacements for legacy N2 controllers. The
N2-capable FX-PC controllers:
•
have the I/O quantities and characteristics of the
FX-PC family controllers
•
must be programmed with FX-PCT, which has
programming capabilities that are similar (but not
identical) to HVACPro, GX9100, GPL, and other
legacy tools
•
support SA Bus devices
•
support FX-WRZ wireless sensors from the controller
using the FX-WRZ7860 receiver when configured for
BACnet MS/TP communication
The N2-capable FX-PC controllers:
•
do not support Zone Bus (for example, TMZ sensors
and M100 actuators)
•
do not support pass through in the commissioning
mode
•
do not support remote downloading or commissioning
using BACnet routing
•
do not support wireless connection to the N2 bus
