Preinstallation Check

Carefully inspect all shipping containers for damage. If any equipment is damaged, notify the delivery service

immediately. Save the damaged shipping container for inspection by the delivery service. After unpacking the

equipment, record all serial numbers. Save the shipping containers and packing material in case it is necessary to

transport or ship any part of the system.

Installation in Hazardous Locations

•This equipment is suitable for use in CLASS I, DIVISION 2, GROUPS A, B, C, D or non-hazardous locations only.

WARNING

•EXPLOSION HAZARD - substitution of components may impair suitability for CLASS I, DIVISION 2;

•EXPLOSION HAZARD - when in hazardous locations, turn off power before replacing or wiring modules; and

•EXPLOSION HAZARD - Do not connect or disconnect equipment unless power has been switched off or the area is

known to be non-hazardous.

Quick Start Guide

1. Install the Communications Carrier on the DIN Rail by simply clicking it into place.

Note: Connecting carriers must be installed on the same section of 35mm x 7.5mm DIN rail.

The DIN rail must have a conductive (unpainted) finish for proper grounding.

(Refer to the heading Module Installation for information about space requirements or module

orientation, or if you are installing the NSM in an area of excessive vibration).

2. Install the Module on the Communications Carrier.

The latch on the module must be in the unlocked position.

Align the connectors and the latch post and press the NSM down until the two tabs on the bottom of

the NSM click into place.

Turn the latch to the locked position to secure the NSM to the top of the carrier.

3. Connect the communications bus to the connector on the front of the Network Slave Module. (Refer to the

heading Bus Installation Guidelines for detailed bus installation instructions.)

4. Remove the connector cover on the right-hand side of the Communications Carrier. Do not discard this cover;

you will need to install it on the last carrier. It protects the connector pins from damage and ESD during handling

and use. Do not remove the connector cover on the left-hand side.

Connector Cover

5. Install additional modules by mounting modules on their carriers and sliding them along the DIN rail to fully

engage the connectors in the sides of the carriers.

6. Power up the System, and Observe the Module LEDs. The LEDs indicate the presence of power and show the

operating mode and status of the NSM.

COM

OK Green indicates the NSM has completed powerup diagnostics and is successfully communicating over the

PLC backplane.

Blinking green indicates that the NSM is in boot mode or its firmware is being updated.

Amber when the NSM has detected a fault, is not communicating over the PLC backplane, or has received

an invalid configuration.

Blinking amber means the NSM has either detected a fault, is not communicating over the PLC backplane,

or has received an invalid configuration.

OFF when the NSM is not receiving power.

COM Green indicates the NSM is online and in network data transfer state.

Blinking green indicates that the NSM is in network data transfer state but not exchanging

communications with the CPU (CPU is stopped).

Amber when the NSM is communicating on the Profibus network but its configuration does not match the

Profibus master.

Blinking amber means the NSM has rejected the configuration from the CPU, or the configuration contains

no network I/O specifications (eg. the default configuration).

OFF when the NSM is offline and has not yet received its configuration from the CPU.

Bus Installation Guidelines

The proper cable for a Profibus network is a shielded twisted pair cable. Profibus cable is sold as "Profibus Network

Cable". The twisted pair cable consists of a Green and a Red wire. Below are some of the cable characteristics of Profibus

cable.

Network Topology

Linear bus, terminated at both ends. Stubs possible.

Medium

Shielded twisted pair cable. Shielding may be omitted, depending on the environment.

Number of Stations

32 stations in every segment without repeaters. With repeaters, extendible up to 127.

Transmission Speed

9.6, 19.2, 93.75, 187.5, 500, 1500 Kbits, 3 Mbits, 6 Mbits, 12 Mbits.

Connector

9-pin D-sub connector

Cable Type

Profibus DP

Impedance

135 to 165 Ohms (3 to 20 MHz)

Capacity

< 30 pF per meter

Resistance

< 110 Ohms per Kilometer

Wire Gauge

> 0.64 mm

Conductor Area

> 0.34 mm2

Bus Length

The maximum bus length using shielded, twisted-pair cable for a single network segment is 1200 meters. Total network

length may be increased with the use of repeaters, up to a maximum of 3 repeaters per network. Other cable types may

be restricted to shorter bus lengths. The maximum bus length also depends on the data rate, as shown in the following

table.

Maximum Bus Length in Meters

Kbits per Second

1,200

9.6

1,200

19.2

1,200

93.75

187.5

400

500

200

1,500

100

3,000; 6,000; 12,000

Often, it is the required bus length that determines the data rate.

For data rates up to 500 kbits/second, follow the stub recommendations of Profibus Part 1. At 1500 kbits/second the

overall drop capacity should be less than 0.2nF. The maximum length of the stub at 1500 kbits/second is 6.6 meters.

Cable shielding is recommended at higher baud rates, to maintain communications integrity in the industrial

environment.

Bus Connectors and Termination

The Network Slave Module provides the Profibus standard female 9-pin D subminiature connectors. Cable connectors

are available from most fieldbus parts distributors as "Profibus 9-pin D connectors". These connectors provide

termination resistors and a switch on the connector to enable/disable termination. Connectors with and without

termination are also available. The connectors label the connections for the twisted pair as cable A and cable B. The

following table illustrates the proper assignment of wire to connector to pin to signal.

Termination resistors are needed, as defined in Profibus Specification DIN 19245 Part 1 section 3.1.2.5.

Termination Required

(Segment 1)

One terminator must be applied at each end of a network segment.

(Segment 1)

Termination Required

(Segment 2)

Important:For proper network termination, the terminating devices must provide and maintain power. Power is

provided by the device on Pin 6 and Ground is provided on Pin 5. If power is lost to either terminating device, the network

may not operate correctly. Generally, the network master device is one of the terminating devices. The other

terminating device may be a critical slave device or a separately powered, stand-alone terminator.

Ru = 390 Ohms

Rt = 220 Ohms

Rd = 390 Ohms

In addition to the termination shown above, the following compensation should be added for 12 Mbit bus technology:

Bus Grounding

Generally, it is only necessary to ensure that the cable shields are attached to ground. In most cable connectors, the

shield is attached to the metal housing of the conductor on the cable side and this is brought to ground by the metal

connector on the NIU.

In some installations with large networks or higher data rates, large ground potentials (greater than ±7V) may arise. In

these cases, it may be necessary to ensure all Profibus devices are attached to the same Protective Earth ground.
