Johnson Controls NIE55 Series, NAE55 Series Installation Manual

NAE55/NIE55 Installation Guide

Application

The Network Automation Engine (NAE) and Network Integration Engine (NIE) are web-enabled,
Ethernet-based, supervisory devices. NAEs and NIEs monitor and control networks of field­level building automation devices, including HVAC equipment, lighting, security, and fire safety
equipment. Figure 1 shows a typical network engine.

In this installation guide, the term network engine applies to any NAE55 or NIE55 model, unless
otherwise stated. For installation instructions on the secure NAE55, refer to the NAE-S Installation
Instructions (Part No. 24-10051-108). For installation instructions on the NAE55s that are approved
for Metasys® system smoke control applications, refer to the NAE55 Installation Instructions (Part No.
24-10051-00132).

The NAE55 models provide integration to the following network protocols: BACnet/IP, BACnet MS/
TP, and N2 Bus, and integrations to other building management communication technologies,
including Modbus®, M-Bus, and KNX. At Release 9.0, the Modbus, M-Bus, and KNX integrations are
added and licensed during network engine commissioning. At Release 10.0, the Modbus, M-Bus,
and KNX integrations are included with the image of the network engine, already pre-licensed and
ready for selection during commissioning. .

Important: For any other custom integrations, contact your local Systems Integration Services
(SIS) team before an upgrade. Updated drivers are available on request.

Note: The NIE55 is available at Release 9.0, but beginning at Release 10.0, the NIE55 is no
longer offered. Also, for installation instructions on the secure NAE55, refer to the NAE-S
Installation Instructions (Part No. 24-10051-108).

Note: Beginning with Metasys Release 10.0, modems (internal and external) and pagers are
no longer supported on NAE55 engines that run the Linux operating system, but are still
supported on prior releases for engines that use a Windows Embedded operating system. If
you receive from the factory a network engine with Release 9.0 that has an internal modem,
you can field-upgrade the engine to Release 10.0 to acquire new release enhancements, but
its modem and pager functionality is lost. If you need modem and pager functionality, do not
upgrade the NAE55 engine to Release 10.0.

Note: If you receive an NAE55 engine from the factory that is imaged with Release 9.0, you
can field-upgrade the engine to Release 10.0 if the upgrade is supported.

Installation

Follow these guidelines when installing the network engine:

• Transport the network engine in the original container to minimize vibration and shock damage
to the network engine.

• Verify that all the parts shipped with the network engine. The data protection battery and
network engine ship together but are packaged separately.

• Do not drop the network engine or subject it to physical shock.

• Do not open the network engine housing (except the data protection battery compartment). The
network engine has no user-serviceable parts inside.

Mounting

Location considerations

Follow these guidelines when mounting the network engine:

• Ensure that the mounting surface can support the network engine and any user-supplied
enclosure.

• Mount the network engine in the proper orientation (Figure 5).

• Mount the network engine on an even surface in wall mount applications whenever possible.
If you must mount the network engine on an uneven surface, be careful not to crack the wall
mount feet or housing when tightening the screws. Use shims or washers to mount the unit
securely on the mounting surface.

3NAE55/NIE55 Installation Guide

• Mount the network engine in areas free of corrosive vapors and observe the environmental
limitations listed in the Technical specifications section.

• Do not mount the network engine on surfaces that are prone to vibration or in areas where
electromagnetic emissions from other devices or wiring can interfere with network engine
communication.

• Allow sufficient space for running cable and wire, making terminal connections, and accessing
battery compartment (Figure 3).

• Mount the power supply above the network engine to ensure adequate heat dissipation and to
position close to the power wiring conduit.

On panel or enclosure mount applications, observe these additional guidelines:

• Do not install the network engine in an airtight enclosure.

• Mount the network engine so that the enclosure wall or the transformer does not obstruct
ventilation of the network engine housing.

Figure 3: Network Engine DIN rail mount dimensions

and mounting space requirements, mm (in.)

Each network engine application is different, and no general guidelines can be given about the
heat dissipating devices that may be mounted in an enclosure with the network engine. Monitor
the network engine processor temperature for each application to determine the acceptable
combinations of devices and proper mounting location for your specific application.

Important: Do not add any devices to an enclosure with a network engine that could cause
the temperature of the network engine processor to exceed 70˚C (158˚F). View the network
engine's CPU Temperature value on the network engine's Diagnostic tab on the Metasys Site
Management Portal. See Technical specifications for ambient condition requirements, and
refer to the Troubleshooting section of the NAE Commissioning Guide (LIT-1201519) for additional
information.

NAE55/NIE55 Installation Guide4

Wall mount applications

To mount the network engine on a vertical surface:

1. Mark the location of the four wall mount feet on the wall using the dimensions in Figure 4 and
an orientation shown in Figure 5, or hold the network engine up to the wall and mark the hole
locations.

Figure 4: Mounting screw hole dimensions, mm (in.)

2. Drill holes in the wall at the marked locations.

3. Insert appropriate wall anchors in all four holes (if necessary) and insert the screws into the
top two holes. Leave enough space between the wall surface and the screw head for the wall
mount feet.

4. Hang the network engine on the screws with the top wall mount feet for horizontal wall mount
applications. Hold the network engine in place for vertical application.

Note: The wall mount feet are designed to make mounting easier. When the network
engine is wall mounted in the horizontal orientation, you can hang the network engine on
the screws with the upper two mount feet (Figure 5).

5. Insert the screws into the lower two wall mount feet and holes and carefully tighten all of the
screws.

Important: Do not overtighten the mounting screws. Overtightening the screws can crack
the network engine wall mount feet or housing.

DIN rail mount applications

To mount the network engine on DIN rails:

1. Mount two DIN rails horizontally, so they are 125 mm (4.9 in.) apart on centers (Figure 3).

2. Snap the DIN clips on the bottom of the network engine to the outward position.

5NAE55/NIE55 Installation Guide

3. Hang the network engine on the DIN rail hooks on the back of the network engine.

Press the DIN clips back into position to secure the unit on the DIN rails.

Figure 5: Required orientations for Network Engine wall mount applications

To remove the network engine from the DIN rails:

1. Snap the DIN clips on the bottom of the network engine to the outward position.

2. Lift the network engine off the DIN rails.

Enclosure mount

To mount the network engine in an enclosure:

1. Mount the enclosure in accordance with the manufacturer’s instructions.

2. Mount the network engine in the enclosure following the guidelines in the Location

considerations and Mounting sections of this document.

NAE55/NIE55 Installation Guide6

Wiring Overview

Power supply, network, and communication connections

See Figure 1 for the location of the power supply terminal, network communication terminals,
Ethernet jack, and modem jack.

Depending on the model, the network engine can connect to an MS/TP field bus trunk, an N2 Bus
trunk, or a LonWorks network trunk. Also, all network engines support two vendor integrations,
such as two Modbus, two M-Bus, or one of each. Or, if a KNX integration is required, three KNX IP
Gateways are supported for one network engine. See Table 13 for a list of all supported dual trunk
applications. The rules, guidelines, and wiring considerations for each type of network or field bus
application are provided in tables of this document.

Power supply

Important: Install the data protection battery before applying 24 VAC power to the network
engine. See the Installing the data protection battery section.

In North America, use a Class 2, 24 VAC power supply with a 50 VA minimum output. Outside North
America, use a 24 VAC SELV transformer at the appropriate rating. The minimum input voltage for
the network engine to operate properly is 20 VAC. See the Technical specifications section.

Use a dedicated power supply to the network engine only. Do not connect any other loads to the
power supply. Additional loads may cause noise interference.

Ethernet port

The Ethernet port, labeled ETHERNET, is an 8-pin RJ-45 network port for connecting the network
engine to Ethernet IP networks. Network engine can connect to Ethernet networks at 10 Mbps, 100
Mbps, or 1 Gbps. This Ethernet port provides IP communications over the building network and to
any third-party integration that uses Ethernet communication, including Modbus TCP, M-Bus TCP,
or KNX.

FC Bus terminal block

The two Field Controller (FC) Bus connections on a network engine are 4-pin removable, keyed
terminal blocks labeled FC-A and FC-B.

The FC bus connections are optically isolated RS-485 ports with keyed 4-position terminal blocks
that communicate at 9.6k, 19.2k, 38.4k, or 76.8k baud. Use an FC Bus port to integrate an N2
network, BACnet MS/TP FC Bus trunk, or third-party network into the Metasys system.

Note: N2, BACnet MS/TP, Modbus RTU, and M-Bus have different protocols and network
requirements. Do not intermix N2, MS/TP, Modbus, or M-Bus devices on the same FC Bus port.

The SHD connections on the FC terminal blocks are not connected to any earth ground connection.
The FC A and FC B terminal blocks are not interchangeable.

LonWorks network terminal block

The LonWorks TP/FT-10 network connection, available only on the network engine LonWorks
model, is a 3-wire removable, keyed terminal block. The Shield connection on the LonWorks
network terminal block is an isolated terminal and is not connected in the network engine. Use the
LonWorks terminal block to connect LonWorks networks to the network engine.

Computer serial ports

The network engine has two RS-232-C serial ports labeled RS232C A and RS232C B (Figure 1). These
serial ports are for direct connection using a standard 9-pin female data terminal equipment (DTE)
to 9-pin female DTE null modem cable. The NAE55 serial ports do not support external modems.

7NAE55/NIE55 Installation Guide

For an NAE55 at Release 9.0, you can use the RS232C A port to connect directly to a computer
serial port to browse to the NAE55. Use this port only for establishing a Point-to-Point Protocol
(PPP) network connection. Refer to the Metasys System Extended Architecture Direct Connection and
Dial-Up Connection Application Note (LIT-1201639). Use the RS232C B port to connect with a VT100
terminal or computer using a VT100 terminal emulator because the RS232C B port outputs the
device IP address. Use this port only to obtain the NAE55 IP address at startup. Refer to the NAE
Commissioning Guide (LIT-1201519).

For an NAE55 at Release 10.0 or later, the RS232C A port is inactive. However, you can use the
RS232C B port to connect a Modbus RTU third-party integration. For more information on how to
use the serial port for third-party vendor integration, refer to the application note for the particular
vendor integration you are installing.

Universal Serial Bus (USB) ports

The two USB ports labeled USB A and USB B are both configured as masters and are independent
of each other. At Release 9.0, you can use USB A port to connect an optional external modem. Refer
to the NAE Commissioning Guide (LIT-1201519) for more information on external modems. At Release

10.0 or later, the use of a USB port to connect an optional external modem is no longer supported.

However, you can use either the USB A or USB B port for debugging purposes when integrating to
a third-party protocol (for example, Modbus, M-Bus, or KNX).

Optional Internal Modem

MS-NAE55x1-x and MS-NIE55x1-x models with Release 9.0 have an internal modem and a 6-pin
RJ-12 modular jack labeled MODEM. Connect a standard phone line plug and cable to the to use the
internal modem.

For information on commissioning an internal modem, refer to the NAE Commissioning Guide
(LIT-1201519).

Wiring the Network Engine

Mount the network engine securely before wiring it. For details, see Mounting.

components carrying hazardous voltage can cause electric shock and may result in severe personal
injury or death.

Warning

Risque de décharge électrique.

Débrancher ou isoler toute alimentation avant de réaliser un branchement électrique. Plusieurs
isolations et débranchements sont peut-être nécessaires pour -couper entièrement l'alimentation
de l'équipement. Tout contact avec des composants conducteurs de tensions dangereuses risque
d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles.

Important: Do not apply 24 VAC power to the network engine before completing and checking
connections. Short circuits or improperly connected wires may result in permanent damage to
the equipment.

Important: Do not apply 24 VAC power to the network engine before installing the data
protection battery. See the Installing the data protection battery section in this document.

Important: Use copper conductors only. Make all wiring in accordance with local, national,
and regional regulations.

Important: Use this MS-NxE55xx-x only as an operating control. Where failure or malfunction
of the NxE55 could lead to personal injury or property damage to the controlled equipment or
other property, additional precautions must be designed into the control system. Incorporate
and maintain other devices, such as supervisory or alarm systems or safety or limit controls,
intended to warn of or protect against failure or malfunction of the NxE55.

Important: Utiliser ce MS-NxE55xx-x uniquement en tant que dispositif de contrôle de
fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du NxE55 risque de
provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la
conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires.
Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes
de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction
d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du NxE55.

Important: The network engine is a low-voltage (<30 VAC) device. Do not exceed the network
engine electrical ratings. Applying high voltage to the network engine may result in permanent
damage to the network engine and void any warranties.

Important: Do not remove the terminal block keys. The terminal block plugs and the terminal
sockets are keyed to fit together in the correct configuration only.

Important: Prevent any static electric discharge to the network engine. Static electric
discharge can damage the network engine and void any warranties.

Be sure to follow these wiring guidelines:

9NAE55/NIE55 Installation Guide

• Route the supply power wires and communication cables at least 50 mm (2 in.) away from the
vent slots in the sides of the network engine housing.

• Provide slack in the wires and cables. Keep cables routed neatly around the network engine to
promote good ventilation, LED visibility, and ease of service.

• Ensure that the building automation network wiring meets the specifications, rules, and
guidelines as outlined in the Wiring considerations and guidelines for network integrations
section. The network engine does not require an earth ground connection.

• Follow the transformer manufacturer’s instructions and the project installation drawings. Power
supply wire colors may be different on transformers not manufactured by Johnson Controls.

• While connecting network devices to 24 VAC power, make sure that transformer phasing is
uniform across all devices. Powering network devices with uniform 24 VAC supply power phasing
reduces noise, interference, and ground loop problems.

Connecting the FC Bus

To connect devices to the MS/TP Field Controller (FC) Bus, complete the following steps:

1. Connect the 3-wire bus cable to the removable blue 4-pin terminal block labeled FC-A as shown
in Figure 6.

Note: The FC-A and FC-B terminals can accept either the MS/TP FC Bus or the N2 Bus, but
not a mixture of both on the same trunk. If you want to integrate both the MS/TP Bus and
the N2 Bus, select one FC terminal for MS/TP FC Bus use and the other for N2 Bus use.

Figure 6: FC Bus terminal block and wiring connections

2. To add additional field devices, wire from one device to the next as shown in Figure 7. Do not
connect more than two wires to each terminal to ensure that a daisy chain configuration is
used.

NAE55/NIE55 Installation Guide10

Figure 7: Daisy chained devices

3. Set each FC EOL switch to their proper positions. See the note in Setting the end-of-line

switches.

Connecting the LonWorks Network

plug labeled LON (Figure 1). The LonWorks network trunk is available on the MS-NAE5520-3
model only.

Figure 8: LonWorks network terminal block and wiring connections

2. To add additional vendor devices, wire from one device to the next in a daisy-chained fashion.
Do not connect more than two wires to each terminal.

11NAE55/NIE55 Installation Guide

Connecting Modbus RTU devices

To connect a Modbus RTU device to the network engine, complete the following steps:

1. For a Modbus RTU device that requires an RS-485 connection, terminate the 3-wire bus cable
from the Modbus device to one of the removable 4-terminal blue plugs on the network engine,
labeled FC-A and FC-B (Figure 9).

Figure 9: FC Bus terminal block and wiring connections

2. For a Modbus RTU device that requires an RS232C serial connection, use a cable to connect
the converter to the RS232C B serial port on the network engine. The maximum cable length
between devices connected though an RS-232 line depends on the baud rate used. In general,
the cable should not exceed 15 meters for 9600 baud.

3. Wire from the RS-485 terminal on the converter to the RS-485 port on the vendor device (Figure

10). The RS-485 bus is a two-wire network.

a. Connect the converter's + A terminal to the device's + (or A) terminal.

b. Connect the converter's - B terminal to the device's - (or B) terminal.

c. If the device has a Signal Ground or Reference terminal, connect this to the converter's

CG2 terminal.

Figure 10: Connection between converter and device

NAE55/NIE55 Installation Guide12

4. To add additional vendor devices, wire from one device to the next in a daisy chain
configuration. The completed wiring should look similar to Figure 11.

Figure 11: Modbus RTU wiring detail overview

Connecting M-Bus devices

To connect a M-Bus device to the network engine, complete the following steps:

1. Connect from the RS232C B serial port on the network engine to the RS-232 connector of the
level converter. Wire to terminals GND, RxD, and TxD as shown in Figure 12.

2. Wire from the M- and M+ terminals on the level converter (Figure 12) to the meters using a
free (star, tree, or line) topology. Specific cabling can vary depending on the topology and site.
See Wiring considerations and guidelines for network integrations.

Note: If the number of M-Bus unit loads or distances exceeds the specifications of a level
converter, an M-Bus repeater can be wired to the converter to increase the number of unit
loads and distances. The converter shown in Figure 12 is capable of handling up to 6 units
loads, while other models can handle up to 100. See Ordering information for a list of M­Bus devices.

3. Connect the 24 VAC supply power wires from the transformer to the -/~ and +/~ terminals as
shown in Figure 12.

13NAE55/NIE55 Installation Guide

Connecting KNX devices

Figure 12: M-Bus Level Converter

1. Connect an Ethernet cable from the building's network jack to the port on the front of the KNX
gateway (Figure 13).

Note: Depending on the size of your network, you can use either a KNX Interface or
Router as a gateway. The Interface connects the network engine to a single KNX line,
while the Router acts as both an Interface and a Line Coupler over Ethernet to connect the
network engine to the network, not to a single device.

2. Connect an Ethernet cable from the building's network jack to the RJ-45, 8-pin Ethernet port on
the network engine.

NAE55/NIE55 Installation Guide14

Figure 13: KNX/IP interface router

3. For a single KNX line, wire from the red and black terminals on the gateway to the devices. For
multiple KNX lines, wire from the red and black terminals on each gateway to the devices on
the same KNX line.

Note: Specific cabling can vary depending on the topology and site. See Wiring

considerations and guidelines for network integrations.

4. Wire each KNX gateway to its own dedicated power supply on the KNX line.

Connecting other third-party devices

The network engine supports several other third-party devices. Refer to the following documents
for information about how to connect the network engine to these devices:

• C•CURE-victor: NAE Commissioning for C•CURE-victor Integration Application Note (LIT-12013151)

NAE55/NIE55 Installation Guide16

Setup and adjustments

Installing the data protection battery

Important: Do not apply 24 VAC power to the network engine before installing the data
protection battery.

To install the data protection battery:

1. Remove the battery from its packaging. Remove the battery cover on the network engine to
expose the battery compartment (Figure 1).

2. Carefully plug the network engine battery connector from the battery compartment into the
connector on the battery cable (Figure 15).

3. Place the battery into the compartment (Figure 15).

4. Slide one end of the battery strap into the hole on the opposite side of the strap (Figure 15),
and loop the strap tightly around the battery to minimize battery movement.

5. Replace the cover of the battery compartment.

Important: The data protection battery must maintain a small residual charge. The battery
ships from the factory with a small residual charge. You should connect 24 VAC power to the
network engine immediately after connecting the battery to ensure that the battery does not
completely loose its charge, which may damage the battery.

Note: The 24 VAC power to the network engine charges the data protection battery. At initial
startup, the battery requires a charging period of at least two hours before it supports data
protection if power fails. Maximum protection (up to three consecutive power failures without
recharging time) requires a 24-hour charging period.

Figure 15: Network Engine data protection battery

17NAE55/NIE55 Installation Guide

Setting the end-of-line switches

The network devices at each end of an FC Bus segment must be set as network terminated devices.
The network engine has two EOL switches (one for each FC Bus) that enable you to set the network
engine as a network terminated device on the bus.

To set a network engine as an FC Bus terminated device, position the switch on the EOL switch
block to the ON position (Figure 16).

Figure 16: FC Bus EOL switch in the factory default ON (up) position

Note: The EOL switches on the network engine are factory set to ON (Figure 16). If the network

engine is not a terminated device on the FC Bus, reposition the switch on the EOL switch block
to the Off (down) position.

Set the EOL switches appropriately for the FC A and FC B buses. The network engine follows the
same rules as other switch-terminating devices listed in the Setting Terminations sections of the

N2 Communications Bus Technical Bulletin (LIT-636018) and the MS/TP Communications Bus Technical
Bulletin (LIT-12011034).

Powering on the Network Engine

Apply power to the network engine by plugging in the gray 2-pin terminal connector to the power
terminal port on the network engine (Figure 1). The network engine requires approximately 3
minutes to start up and become operational. See the LED test sequence at startup section.

Startup is complete and the network engine is operational when the (green) RUN LED is On steady
and the (red) GEN FAULT LED is Off. See Figure 17 for LED locations.

Disconnecting power from the Network Engine

Important: The data protection battery must be installed and charged before disconnecting
the 24 VAC supply power.

Disconnect power from the network engine by removing the gray 2-pin terminal block from the
power terminal port on the network engine (Figure 1).

When you remove 24 VAC power from the network engine, or supply power is lost, the network
engine is nonoperational. The POWER LED (Figure 17) remains On, and the data protection battery
continues to power the network engine for approximately 1 to 3 minutes so that volatile data can
be backed up in nonvolatile memory. The POWER LED goes Off when the data backup is completed.

NAE55/NIE55 Installation Guide18

Troubleshooting

LED status indicators

The LEDs on the front cover of the network engine indicate power and communication status. See
Figure 17 and Table 2.

LED test sequence at startup

During startup, the network engine automatically initiates an LED test to verify the operational
status of the LEDs. Immediately after connecting supply power, the following LED lighting sequence
occurs:

1. The network engine emits one short beep, indicating that the BIOS startup was successful.

2. The PEER COM, RUN, and GENL FAULT LEDs turn on, indicating that the OS is booting up. For
network engine models, the FC A and FC B LEDs also turn on.

3. The PEER COM, RUN, GENL FAULT LEDs, and the FC A and FC B LEDs shut off. The RUN LED
flashes to indicate that the network engine software is loading.

4. The LEDs display the operational status of the network engine. When the RUN LED goes On
Steady, the operating system and Metasys application are running and the network engine is
ready.

The total time to start up the network engine depends on the size of the database and can take
several minutes.

Figure 17: Network Engine with LED designations

19NAE55/NIE55 Installation Guide

System re-boot switch

The System Re-Boot switch (Figure 1) forces a manual restart of the network engine processor. All
data changes made to the system since the last time the network engine saved data are lost on
restart, including alarm, trend, and audit trail data.

Note: Press the System Re-Boot switch only if the network engine fails to respond and cannot
be accessed by any user device. Do not press the System Re-Boot switch unless you have tried
other reasonable means to fix the problem.

Varies (see
next column)

Flicker = Data traffic between network engines. For a network
engine that is not a Site Director, this LED indicates regular
heartbeat communications with the Site Director. For a Site
Director network engine, flashes are more frequent and
indicate heartbeat communications from all other network
engines on the site. For a single network engine on a network
without an ADS, there is no flicker.

Run (Green) On Steady On Steady = network engine software is running.

On 1 second, Off 1 second = network engine software is in
startup mode.

On 0.5 seconds, Off 0.5 seconds = network engine software is
shutting down.

Off Steady = Operating system is shutting down or software is
not running.

24 VAC (Green) On Steady On Steady = 24 VAC power is present.

Off Steady = Loss of 24 VAC power. In the Off Steady condition,
the network engine can be running on battery power. Also see
the POWER LED.

BATT FAULT (Red) Off Steady On Steady = Battery fault. Replace the battery. Battery is not

connected or cannot be charged. The BATT FAULT LED may
remain On for up to 24 hours after initially powering on the
network engine. If the BATT FAULT LED remains on longer than
48 hours after initially powering on the network engine, check
the battery connection or replace the battery.

GENL FAULT (Red) Off Steady On Steady = General Fault. Fault conditions are user

configurable in software. Preconfigured fault conditions
include excessive memory use, excessive flash use, excessive
CPU or PWB temperature, and Battery Fault. In normal
operation, the GENL FAULT LED stays on steady for the first
half of the startup sequence.
