Introduction
The NAE55 is a specific series of network engine
that performs a key role in the Metasys system
architecture. Network engines provide network
management and system-wide control and
coordination over one or more Metasys equipment
controller networks, that include the following
series:
• CG series General Purpose Application Equipment
Controllers
• CV series VAV Box Controllers
• FAC and FEC series Field Equipment Controllers
• VMA series VAV Box Controllers
• TEC series Terminal Equipment Controllers
• LN series Equipment Controllers
• Legacy Metasys controllers, such as Unitary
(UNT) controllers, Variable Air Volume Assembly
(VMA14xx) controllers, and DX-9100 controllers
• Third-party equipment controllers
Note: The following IP controllers at
firmware 10.0 support BACnet™/IP and
BACnet/SC at Release 12.0.
- M4-CGE09090-0/-0H
- M4-CGE04060-0
- M4-CVE03050-0P
- MS-FAC4911-0
- MS-VMA1930-0
You can connect these network engines together
to scale up on large projects. For additional
functionality and site unification, you can network
the engines with an Application and Data Server
(ADS), an Extended Application and Data Server
(ADX), or an Open Application Server (OAS).
Use network engines for building control
scheduling, alarm and event management, energy
management, data exchange, historical data
storage and management, and custom control logic.
The NAE55 includes an embedded user interface
called the Site Management Portal (SMP). Users
access the SMP for system navigation and operation
with a web browser. To prevent unauthorized
access, network engines use password protection,
permission access, and IT security best practices.
Network engines provide network supervisor
capabilities, IP network connectivity, and third-party
device integration capabilities. NAE55s at Release
11.0 or later are FIPS 140-2 Level 1 compliant. The
Federal Information Processing Standard (FIPS)
140-2 is a United States government cybersecurity
standard that approves cryptographic modules/
algorithms used for encryption.
For information about the latest family of network
engines that are available at Release 10.1 or
later, refer to the SNE/SNC Product Bulletin
(LIT-12013296). For information about other
network engine models, refer to the NAE55 Catalog
Page (LIT-1900195). For information about network
engines that have approval for use at facilities that
require regulatory compliance, refer to the Metasys
for Validated Environments, Extended Architecture
Product Bulletin (LIT-12011326).
Application documentation
Refer to the Network Engines Product Bulletin
(LIT-12012138) for important product application
information.
Features and benefits
The following features and benefits are applicable to
all network engines, with specific features that vary
by model and software release.
Supervision of controller networks including
Johnson Controls and third-party protocol
devices
Support for connectivity to open network standards
for field device flexibility. Supported protocols are
model and software release dependent and include
BACnet/IP, BACnet Secure Connect (BACnet/SC),
BACnet MS/TP, LonWorks, N2 Bus, Modbus RTU,
Modbus TCP, M-Bus (EN 13757-3) serial and IP, KNX
IP, SIMPLEX® Fire, Zettler Fire Panel, Tyco C•CURE,
OPC Unified Architecture (UA), and other third-party
protocols.
Communication using commonly accepted IT
standards at the automation and enterprise level
The Metasys System installs on the IT infrastructure
in your building or enterprise and uses standard IT
communication services over the company Intranet,
WAN, public Internet with VPN tunnel, or firewall
protection. Network engines also support the ability
to optionally authenticate non-local users through
Syslog Destination Delivery Agent (DDA) for network
logging of Metasys audits and events.
FIPS compliance
Common to all network engines that run Release
11.0 or later firmware, the FIPS 140-2 feature
provides FIPS compliance to a customer's Building
Automation System (BAS). For a site to be fully FIPS
compliant, you need to upgrade all network engines
to Release 11.0 or later, then install and license the
FIPS 140-2 feature on the Metasys Server.
BACnet/SC
BACnet/SC is a recent update to the BACnet
interoperability standard to improve cybersecurity
and network infrastructure integrity. BACnet/
SC identifies a secure, encrypted datalink layer
designed to meet the requirements, policies, and
constraints of IP networking infrastructures.
Secure web-based user interface
Access system data in the network engines from
any device that is connected to the network with
a supported web browser. All upgraded network
engines have self-signed certificates for encrypted
communication. Optionally, you can deploy
trusted certificates to the network engines that the
customer's IT department or a Certificate Authority
(CA) provide and manage.
Site Director function
If you set up one network engine as a Site Director,
you can access all site data from that single device.
The device that is designated as the Site Director
coordinates the display of data from a maximum of
three engines for easy navigation through the entire
site. This capability is available to all network engine
models.
Embedded user interface and online system
configuration software
Use the password-protected software to enable,
configure, commission, archive data, monitor,
command, and perform system diagnosis from any
device through a web browser, without the need for
separate workstation software.
Linux® operating system
The NAE55 network engines at Release 10.0 and
later run on Linux, which is a robust, widelyaccepted, and readily-supported operating system.
Background file transfer
With this new feature, you can transfer firmware
upgrades, archive databases, HTTPS security
certificates, and security databases from the
System Configuration Tool (SCT) to the NAE55
while the engine remains operational, minimizing
system disruptions. Background file transfer is
only available for NAE55s at Release 10.1 or later,
and for the new family of SNE and SNC network
engines that were introduced at Release 10.1. For
information about the newest engines, refer to the
SNE/SNC Product Bulletin (LIT-12013296)
Ordering information
Contact the nearest Johnson Controls representative to order a network engine. The following tables list the
product code numbers and accessories for all available network engines based on model. If you receive an
NAE55 engine from the factory that is imaged with an older release, you can field-upgrade the engine to
Release 12.0 if the upgrade is supported. To order repair parts, add -702 or -703 in place of the last number
(for example, MS-NAE5521-703).
