Introduction

This document describes how to connect the NI 9144 chassis to a network,

how to use the NI 9144 chassis features, and contains the NI 9144 chassis

specifications. The NI 9144 is a slave device and requires a compliant

EtherCAT Master and network to function.

Safety Guidelines

Operate the NI 9144 chassis only as described in this user guide.

Safety Guidelines for Hazardous Locations

The NI 9144 chassis is suitable for use in Class I, Division 2, Groups A, B,

C, D, T4 hazardous locations; Class 1, Zone 2, AEx nA IIC T4 and Ex nA

IIC T4 hazardous locations; and nonhazardous locations only. Follow these

guidelines if you are installing the NI 9144 chassis in a potentially

explosive environment. Not following these guidelines may result in

serious injury or death.

Caution Do not disconnect the power supply wires and connectors from the chassis unless

power has been switched off.

Caution Substitution of components may impair suitability for Class I, Division 2.

Caution For Zone 2 applications, install the system in an enclosure rated to at least IP 54

as defined by IEC 60529 and EN 60529.

Special Conditions for Hazardous Locations Use

in Europe

This equipment has been evaluated as Ex nA IIC T4 equipment under

DEMKO Certificate No. 07 ATEX 0626664X. Each chassis is marked

II 3G and is suitable for use in Zone 2 hazardous locations, in ambient

temperatures of –40 ≤Ta ≤ 70 °C.

Special Conditions for Marine Applications

Some chassis are Lloyd’s Register (LR) Type Approved for marine

applications. To verify Lloyd’s Register certification, visit ni.com/

certification and search for the LR certificate, or look for the Lloyd’s

Mounting the NI 9144 Chassis

You can mount the chassis in any orientation on a 35 mm DIN rail or on a

panel. Use the DIN rail mounting method if you already have a DIN rail

configuration or if you need to be able to quickly remove the chassis. Use

the panel mount method for high shock and vibration applications.

Caution Your installation must meet the following requirements for space and cabling

clearance:

• Allow 25.4 mm (1 in.) on the top and the bottom of the chassis for air circulation.

• Allow 50.8 mm (2 in.) in front of C Series I/O modules for cabling clearance for

common connectors, such as the 10-terminal, detachable screw terminal connector, as

shown in Figure 2.

The following sections contain mounting method instructions. Before

using any of these mounting methods, record the serial number from the

back of the chassis. After the chassis is mounted, you will not be able to

read the serial number.

Caution Remove any C Series I/O modules from the chassis before mounting it.

Mounting the NI 9144 Chassis on a Panel

Use the NI 9905 panel mount kit to mount the NI 9144 chassis on a flat

surface. To use the NI 9905 panel mount kit, complete the following steps:

1. Fasten the chassis to the panel mount kit using a number 2 Phillips

screwdriver and two M4 ×16 screws. National Instruments provides

these screws with the panel mount kit. You must use these screws

because they are the correct depth and thread for the panel.

Mounting the Chassis on a DIN Rail

Use the NI 9915 DIN rail mount kit if you want to mount the chassis on a

DIN rail. You need one clip for mounting the chassis on a standard 35 mm

DIN rail. Complete the following steps to mount the chassis on a DIN rail:

1. Fasten the DIN rail clip to the chassis using a number 2 Phillips

screwdriver and two M4 ×16 screws. National Instruments provides

these screws with the DIN rail mount kit.

Figure 7. Installing the DIN Rail Clip on the NI 9144 Chassis

2. Insert one edge of the DIN rail into the deeper opening of the DIN rail

clip, as shown in Figure 8.

Figure 8. One Edge of the DIN Rail Inserted in a Clip

©National Instruments Corporation 9 NI 9144 User Guide and Specifications

3. Press down firmly on the chassis to compress the spring until the clip

locks in place on the DIN rail.

Caution Remove any C Series I/O modules from the chassis before removing the chassis

from the DIN rail.

Connecting the NI 9144 Chassis to a Network

NI recommends that you install a private network segment for your

deterministic Ethernet expansion devices. Slave devices cause network

flooding on a standard network. Non-EtherCAT frames jeopardize the

system performance and determinism on an EtherCAT network. Refer to

the EtherCAT Technology Group Web site at www.ethercat.org, for

more information.

The following devices are required to connect the NI 9144 chassis to a

network successfully: a host computer, a supported LabVIEW Real-Time

target1with the NI-Industrial Communications for EtherCAT software

driver installed on it, and an NI 9144 slave device.

To have your LabVIEW target establish a connection with the NI 9144

chassis, connect the secondary port of the LabVIEW Real-Time target to

the NI 9144 IN port. Use a standard Category 5 (CAT-5) or better Ethernet

cable. Use the NI 9144 OUT port to connect to other NI 9144 chassis and

slave devices on the same segment.

Once the connection is established, install the NI-Industrial

Communications for EtherCAT software on the host computer and then use

Measurement and Automation Explorer (MAX) to install the NI-Industrial

Communications for EtherCAT driver on the target.

Caution To update your firmware on the NI 9144 chassis, refer to the Updating your

Firmware section of this user guide.

Caution To prevent data loss and to maintain the integrity of your EtherCAT installation,

do not use a CAT-5 Ethernet cable longer than 100 m. National Instruments recommends

using a CAT-5 or better shielded twisted-pair Ethernet cable. If you need to build your own

cable, refer to the Cabling section for more information about Ethernet cable wiring

connections.

Note If you are not using a LabVIEW Real-Time target as the master controller, consult

your product documentation about networking connections.

1 Supported LabVIEW targets include the NI cRIO-9074 and PXI RT with the NI PXI-8231 Ethernet interface.
