Issued August 2017

Refer to the QuickLIT website for the most up-to-date version of this document.

Application

Important: NIEx9s are compatible with Metasys® system Release 7.0 and later. You may apply the dual trunk

integration feature to NIEx9s purchased prior to the current release by using the NIEx9 Driver Manager
tool. For information on how to apply the latest package and license files that support dual trunks, refer
to the NIEx9 Driver Manager Application Note (LIT-12011919).

The Metasys Network Integration Engine (NIE) controller is a web-enabled, Ethernet-based, supervisory device that
serves two roles. Its first role is to integrate the Metasys Building Management System to other standard building

management communication technologies. Integrations include the following network protocols: BACnet®, LONWORKS®,
N2 Bus, Modbus®, Meter-Bus (M-Bus, European Standard EN 1434-3), KNX, and other third-party proprietary

protocols. In this capacity, the NIE29 monitors and supervises a wide variety of HVAC, lighting, security, fire, electrical
and thermal measuring and access control equipment.

Its second role is to provide the I/O point connectivity and digital control capabilities of a Metasys Field Equipment
Controller (FEC). In this capacity, the NIE29 Series controller provides a cost-effective solution designed for central
plant applications and large built-up air handlers.

For the Modbus and M-Bus protocols, one NIE29 can support two integrations: two Modbus, two M-Bus, or one of
each, significantly expanding the engine's flexibility. See Table 11 for a list of all supported dual trunk applications.

Important: The NIE29 is shipped with a license and driver for the communication protocol that was ordered. If you

re-image the engine, the license and driver are deleted and the engine is not able to communicate with
the required protocol. If you need to re-image the engine, use the NIEx9 Driver Manager first to preserve
the protocol driver and license file before you re-image. For details, refer to the NIEx9 Driver Manager

Application Note (LIT-12011919).

Wiring

Power Supply, Network, and Communication Connections

See Figure 1 for the location of the NIE’s power supply terminal, bus terminals and ports, USB port, and Ethernet
port.

Note: Do not remove the red terminal block keys from the board mounted terminal blocks. Removing the keys can

result in a removable terminal plug being plugged into the wrong terminal block, which can cause the NIE to
malfunction.

24~ Supply Power Terminal Block

The 24~ supply power terminal block is a gray, keyed, removable 3-terminal block located on the top side of all NIE
models (Figure 1 and Figure 13).

In North America, the NIE requires a Class 2, 24 VAC, 25 VA minimum power supply. Outside North America, use
a 24 VAC safety extra-low voltage (SELV) transformer at the appropriate rating. A minimum input voltage of 20 VAC
is required for the NIE to operate properly.

Note: The maximum power consumption of an NIE29 is 25 VA, but that does not include power for internally sourced

binary output (BO) points. Applications that provide power to BO points and configurable output (CO) points
configured as BO points can require up to 125 VA of additional power over the 25 VA minimum required for
the NIE29.

SA Bus Terminal Block

The brown, keyed, removable, 4-terminal SA BUS terminal block (Figure 1) is provided on all NIE models. Connect
the 4-wire SA Bus cable to the SA BUS terminal block. See the SA Bus Rules section for more information.

SA Bus Modular Port

The 6-Pin modular Sensor/Actuator (SA) Bus port is available on all NIE models (Figure 1 and Figure 4). The SA
BUS port connects to:

• a Wireless Commissioning Converter (MS-BTCVT-1) to commission the NIE with the Controller Commissioning
Tool

• a DIS1710 Local Controller Display to provide a display screen on NIE29 models without an integral display
screen

• an NS Series Network Sensor to provide room temperature data to the NIE

field buses and is available on NIE models that support N2 Bus, Master-Slave/Token-Passing (MS/TP) FC Bus
applications. Depending on the NIE29 model:

• connect the 3-wire N2 Bus to the FC BUS terminal block on NIE models that support N2 Bus applications. See

Figure 5 and the N2 Bus Rules section for more information.

• connect the 3-wire MS/TP FC Bus to the FC BUS terminal block on NIE models that support MS/TP FC Bus
applications. See Figure 5 and the MS/TP Bus Rules section for more information.

The SHLD terminal on the FC BUS terminal block can be used as a convenient terminal to connect cable shield
drains in daisy-chain bus applications that use shielded cable.

FC Bus Modular Port

The 6-pin modular Field Controller (FC) BUS port is available only on NIE models that support MS/TP or N2 Bus
applications (Figure 1 and Figure 4). Connect a Wireless Commissioning Converter (MS-BTCVT-1) to the modular

FC BUS port to commission the NIE with the Controller Configuration Tool (CCT).

LONWORKS® Network Terminal Block

The blue, keyed, removable, 3-position LON terminal block connects a LONWORKS network trunk to NIE29 models
that support a LONWORKS network trunk. The shield (SHD) on the LON terminal block is soft grounded to the NIE
chassis terminal, and you can use it as a convenient terminal to connect cable shield drains in daisy-chain bus
applications that use shielded cable.

RS232C Serial Port

The RS232C serial port provides direct connection to a Modbus RTU or M-Bus network using a standard 9-pin
female data terminal equipment (DTE) to 9-pin female DTE null modem cable. Integration of only one device is
permitted. If the RS232C serial port is not used to integrate a vendor protocol, you can connect to a computer serial
port to browse to the NIE or to connect to a VT100 or a computer with a VT100 emulator and perform diagnostic

procedures. Refer to the Metasys® System Extended Architecture Direct Connection and Dial-Up Connection

Application Note (LIT-1201639) for more information about direct connections to an NIE.

Standard USB Port

The USB port connects to an external flash drive that can store diagnostic information when the NIE is placed in
diagnostic mode. You can otherwise configure the USB serial port to use an optional, user-supplied external modem.

5NIE29 Installation Instructions

Ethernet Port

The Ethernet port, labeled ETHERNET, is an 8-pin RJ-45 network port for connecting the NIE to Ethernet networks.

6NIE29 Installation Instructions

Wiring the NIE

Important: Do not connect 24 VAC supply power to the NIE before finishing wiring and checking all wiring

connections. Short circuits or improperly connected wires may result in permanent damage to the
equipment.

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

The NIE is a low-voltage device (<30 VAC) in North America and an extra low-voltage device in Europe.
Do not exceed the NIE electrical ratings.

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 NIE. Static electric discharge can damage the NIE and void

any warranties.

Important: Ensure the network and field bus wiring meets the specifications, rules, and guidelines in the Power

Supply, Network, and Communication Connections section in this document.

Mount the NIE securely before wiring the NIE.

Follow these guidelines when wiring an NIE:

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

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

Wiring the NIE for N2, MS/TP, LONWORKS, or Modbus RTU Protocol

1. Connect the Ethernet cable to the RJ-45, 8-pin Ethernet port on the NIE shown in Figure 1.

2. If using an external modem, connect the modem to USB A using the proper cable.

3. Connect the Building Automation System (BAS) network cables to the appropriate ports.

For an N2 or MS/TP network, connect the 3-wire bus cable to one of the removable 4-terminal blue plugs

•

labeled FC Bus (Figure 5).
Note: If an N2 or MS/TP bus is connected to the NIE, you must set the NIE EOL switches to the proper

positions. See the Setting the End-of-Line Switch section. The Modbus RTU network does not require
termination.

• For LONWORKS compatible networks, connect the 2-wire cable from the LONWORKS network trunk to the

removable 3-terminal blue plug labeled LON (Figure 6).
Note: The LONWORKS network trunk is available on the NIE292x-0 model only.

4. For Modbus RTU (RS-485) protocol, use a cable to connect the RS-232/RS-485 converter to the RS232C serial
port on the NIE.
Note: The maximum cable length between devices connected though an RS-232 line depends on the baud

rate. In general, the length should not exceed 15 meters at 9600 baud.

5. Terminate the wires from the RS-485 terminal on the converter to the RS-485 port on the vendor device (Figure

7). 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.

8NIE29 Installation Instructions

Figure 7: Connection Between Converter and Device

6. Set the NIE EOL switches to the proper position. See Setting the End-of-Line Switch.

7. To add additional vendor devices, terminate the wires from one device to the next as shown in Figure 8. No more
than two wires may be connected to each terminal to ensure the daisy chain configuration. See Wiring Rules for

Networks and Field Buses for the Modbus protocol.

Figure 8: Daisy Chained Devices

The completed wiring should look similar to Figure 9.

Figure 9: Modbus RTU Wiring Detail Overview

8. Terminate the 24 VAC supply power wires from the transformer to the removable power terminal block plug on
the NIE (Figure 10).

9NIE29 Installation Instructions

Figure 10: 24 VAC Supply Power Wiring

Note: Power supply wire colors may be different on transformers not manufactured by Johnson Controls. Follow

the transformer manufacturer’s instructions and the project installation drawings.

9. Terminate the 24 VAC supply power wires from the transformer to the converter. No additional external power
adapter is required. Terminate the hot and common wires as desired. The NIE does not require an earth ground
connection.
Note: The 24 VAC power should be terminated to all network devices so transformer phasing is uniform across

the devices. Powering network devices with uniform 24 VAC supply power phasing reduces noise,
interference, and ground loop problems.

Wiring the NIE for M-Bus Protocol

1. Connect the Ethernet cable to the RJ-45, 8-pin Ethernet port shown in Figure 1.

2. Connect from the RS232C serial port on the NIE to the RS-232 connecter of the level converter. Wire to terminals
GND, RxD, and TxD as shown in Figure 11.

3. Terminate the M- and M+ wires on the level converter (Figure 11) to the meters using a free (star, tree, or line)
topology. Specific cabling can vary depending on the topology and site. See Wiring Rules for Networks and Field

Buses.

Note: If the number of M-Bus unit loads or distances exceeds the specifications of a level converter, you can

connect an M-Bus repeater to the converter to increase the number of unit loads and distances. The
converter shown in Figure 11 is capable of handling up to 6 units loads, while other models can handle
up to 100. See NIE29 Model Ordering Information Table for a list of M-Bus devices.

4. Terminate the 24 VAC supply power wires from the transformer to the removable power terminal block plug on
the NIE (Figure 10).
Note: Power supply wire colors may be different on transformers not manufactured by Johnson Controls. Follow

the transformer manufacturer’s instructions and the project installation drawings.

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

11.

10NIE29 Installation Instructions

Figure 11: M-Bus Level Converter

Wiring the NIE for KNX Protocol

1. Connect an Ethernet cable to the RJ-45, 8-pin Ethernet port shown in Figure 1.

2. Connect another Ethernet cable to the port on the front of the KNX gateway (Figure 12).
Note: Depending on the size of your network, you can use either a KNX interface or router as a gateway. The

Interface connects the NIE to a single KNX line, while the router acts as both an interface and a line
coupler over Ethernet to connect the NIE to the network, not to a single device.

11NIE29 Installation Instructions

Figure 12: KNX/IP Interface Router

3. For a single KNX line, terminate the wires from the red and black terminals on the gateway to the devices. For
multiple KNX lines, terminate the wires 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 Rules for Networks and Field

Buses.

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

Wiring Input and Output Terminals

NIE29 Series models support up to 33 hard-wired I/O points including:

• 7 BO points

• 4 CO points

• 4 analog output (AO) points

• 8 binary input (BI) points

• 10 Universal Input (UI) points

See Figure 13, Figure 14, and Terminal Wiring and Cable Length Guidelines Tables for more information.

The I/O points are designed for multiple types of input or output, and most of the points are configured in the CCT
software.

Terminal Functions, Ratings, Requirements, and Wiring Guidelines

Input and Output Wiring Guidelines

Table 12 provides information and guidelines about the functions, ratings, and requirements for the NIE input and

output terminals and references to guidelines for determining proper wire sizes and cable lengths.

12NIE29 Installation Instructions

In addition to the wiring guidelines in Table 12, observe these guidelines when wiring NIE inputs and outputs:

• Run all low-voltage wiring and cables separate from high-voltage wiring.

• All input and output cables, regardless of wire size or number of wires, should consist of stranded, insulated,
and twisted copper wires.

• Shielded cable is not required for input or output cables.

• Shielded cable is recommended for input and output cables that are exposed to high electromagnetic or radio
frequency noise.

Inputs/outputs with cable runs under 30 m (100 ft) typically do not require an offset in the software setup. Cable runs
over 30 m (100 ft) may require an offset in the input/output software setup.

Table 13 defines cable length guidelines for the various wire sizes that may be used for input and output wiring.

Maximum Cable Length versus Load Current

Use Figure 15 to estimate the maximum cable length relative to the wire size and the load current (in mA) when
wiring inputs and outputs.

FC and SA Bus and Supply Power Wiring Guidelines

Table 14 provides information about the functions, ratings, and requirements for the NIE communication bus and

supply power terminals, and guidelines for wire sizes, cable types, and cable lengths when wiring the NCE
communication buses and supply power.

In addition to the guidelines in Table 14, observe these guidelines when wiring the SA/FC Buses and supply power:

• Run all low-voltage wiring and cables separate from high-voltage wiring.

• All FC and SA Bus cables, regardless of wire size, should be twisted, insulated, stranded copper wire.

• Shielded cable is strongly recommended for all FC and SA Bus cables.

•

Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for detailed information regarding
wire size and cable length requirements for the FC and SA buses.

Setup and Adjustments

Data Protection Battery

The NIE is shipped with the data protection battery installed and connected. Do not disconnect the battery for any
reason other than to replace a defective battery.

The 24 VAC supply power to the NIE charges the data protection battery. At initial startup, the battery may require
a charging period of at least 4 hours before it supports data protection if power fails. Maximum protection (up to 3
consecutive power failures without recharging time) requires a 15-hour charging period.

The data protection battery slowly loses charge when 24 VAC power is removed from the NIE. If the battery completely
loses charge, the NIE real-time clock stops.

24NIE29 Installation Instructions

Whenever an NIE is disconnected from 24 VAC power for over 30 days, ensure that the real-time clock is set properly
and that the NIE is powered long enough to recharge the data protection battery.

Powering On the NCE

After applying 24 VAC power, the NIE requires approximately 5 minutes to start up and become operational. See
the LED Test Sequence at Startup.

Startup is complete and the NIE is operational when the green RUN LED is On steady and the red FAULT LED is
Off (LED Status Indicators).

Important: Wait for the NIE to complete the start-up sequence and the RUN LED to go On steady before initiating

any other action on the NIE.

Disconnecting Power from the NCE

When 24 VAC supply power to an NIE is disconnected or lost, the NIE is nonoperational, but the POWER LED
(Figure 18) remains On and the data protection battery continues to power the NIE for several (approximately 1 to

8) minutes while volatile data is backed up in nonvolatile memory. The RUN LED goes Off when data backup and

shutdown is complete.

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

power.

Setting the End-of-Line Switch

RS485 serial protocol bus segments require proper EOL termination to reduce interference from signal bounce back
on the bus segment.

FC Bus MS/TP and Mobus RTU applications require a terminated device at each end of each FC Bus segment. See
the MS/TP Bus Rules section for more information on EOL requirements on an FC Bus.

N2 Bus applications are self terminating and have no EOL setting. See the N2 Bus Rules section for more information
on EOL requirements on an N2 Bus.

The NIE29 models that support MS/TP FC Bus applications or N2 Bus applications have an EOL switch, which must
be set according to the position of the NIE on the FC Bus or N2 Bus segment. The NIE29 is shipped with the EOL
switch in the factory default, ON (up) position (Figure 16).

Figure 16: FC Bus EOL Switch in the Factory Default ON (Up) Position

See to determine the appropriate EOL switch setting for the NIE in your field bus application.

25NIE29 Installation Instructions

Figure 17: EOL Switch Setting Relative to NIE Position on the N2 Bus or FC Bus Segment

Setting the Network and Device Addresses

You must assign a new IP network address to the NIE29, so it can communicate on the IP Ethernet network. The
NIE29 MAC address is fixed and is printed on a label on the housing.

The NIE29 is always the SA Bus supervisor and, therefore, always has a fixed device address of 0 on the SA Bus.

The supervisory controller on NIE29 models that support an (MS/TP) FC Bus is always an FC Bus supervisor and
has a fixed device address of 0 on the FC Bus. The field controllers in all the NIE29 models have fixed device
addresses of 4 on the NIE FC Bus.

Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for more information on device addresses
on (MS/TP) FC Buses and SA Buses.

NIE29 models that support an N2 Bus are always bus supervisors on the N2 Bus, and they do not require a user
assigned device address to communicate on the N2 Bus.

NIE29 models that support a LONWORKS network trunk are assigned a unique, factory-assigned Neuron® ID. A

network management tool, such as LN Builder, uses this Neuron ID to set the domain, subnet, and node address
of the NIE29 for communication with LONWORKS devices.

The NIE29 Modbus integration always serves as a Modbus master and does not require a user-assigned device
address.

Binary Output Source Power Selection Jumpers

The BO source power selection jumpers determine whether a BO provides internal power (sourced from the NIE)
to the output load (INT position) or requires an external power source (EXT position) for the output load. Figure 13
shows an example of the NIE controller BOs and the associated power selection jumpers next to the BO terminal
blocks.

Position the jumpers next to the BO terminals to provide either internal 24 VAC power to the BO load or act as a
switch for an externally powered BO. Each NIE29 BO wired in an application must have the jumpers positioned
properly for the application. See Figure 13.

Important: Do not connect an external power source to a BO when the BO power source jumper is in the internal

power (INT) position. Connecting external power to a BO that sources internal power can damage the
controller and void any warranties.

26NIE29 Installation Instructions

Display Screen and Display Navigation Keypad

Specified NIE29 models feature an integral display screen and display navigation keypad that allow you to view and
edit the I/O points settings on the NIE29 (Figure 1). Refer to the DIS1710 Local Controller Display Technical Bulletin
(LIT-12011270) for more information on using the display screen and keypad.

Troubleshooting

LED Status Indicators

The NIE29 models have up to 10 LEDs (depending on model) to indicate power and network communication status.

Figure 18 shows the LEDs and Table 15 describes the LED indications.

Figure 18: NIE29 LED Designations

LED Test Sequence at Startup

During startup, the NIE automatically initiates an LED test to verify the operational status of the LEDs. Immediately
after power is supplied to the NIE, the following LED lighting sequence occurs:

1. The POWER, BATT FAULT, 10 LINK, FAULT, RUN, and PEER COM LEDs turn On, indicating that the operating
system (OS), is starting. (After 2 seconds, the LEDs may change states depending on the site-specific network
activity.)

2. The BATT FAULT, PEER COM, and FAULT LEDs shut Off. The RUN LED flashes to indicate that the NIE
software is loading.

3. The LEDs display the operational status of the NIE. When the RUN LED goes On Steady, startup is complete
and the NIE is operational.

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