Johnson Controls MS-NAE5520-0 Network Engine

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 networks of Metasys

equipment controllers, including the following:

• General Purpose Application MS/TP Controllers (CGMs)

• VAV Box Equipment MS/TP Controllers (CVMs)

• Field Equipment Controllers (FECs) and Advanced

Application Field Equipment Controllers (FACs)

• Terminal Equipment Controllers (TECs)

• LN (LonWorks® Network) 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

Network engines can be networked together

for scaling up on large projects, and they can be

networked with an Application and Data Server

(ADS), an Extended Application and Data Server

(ADX), or an Open Application Server (OAS) for

additional functionality and site unification.

Network engines provide building control

scheduling, alarm and event management, energy

management, data exchange, historical data

storage and management, and custom control logic.

These network engines include an embedded user

interface called the Site Management Portal (SMP).

Users access the SMP for system navigation and

operation using web browser connections. Network

engines are secured from unauthorized access

using password protection and permission access

control as well as IT security best practices.

Network engines provide network supervisor

capabilities, IP network connectivity, and third-party

device integration capabilities. NAE55s at Release

11.0 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 newest 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 NCE25. NAE35. and NAE45

Catalog Page (LIT-1901147), Secure Network Engine

Catalog Page (LIT-1900996), and NAE85 Catalog

Page (LIT-1901148). Lastly, refer to the Metasys for

Validated Environments, Extended Architecture Product

Bulletin (LIT-12011326) for information about which

network engines are approved for use at facilities

that require regulatory compliance.
