ATTENTION: Risk of equipment damage exists. Remove power before

installing or removing the 1769-SM2 module. When you install or remove

the module with power applied, an electrical arc may occur. An electrical

arc can cause personal injury or equipment damage by:

•Sending an erroneous signal to your system’s field devices, causing

unintended machine motion.

•Causing an explosion in a hazardous environment.

Electrical arcing causes excessive wear to contacts on both the module

and its mating connector. Worn contacts may create electrical resistance.

ATTENTION: Risk of equipment damage exists. The 1769-SM2

module contains ESD (Electrostatic Discharge) sensitive parts that can be

damaged if you do not follow ESD control procedures. Static control

precautions are required when handling the module. If you are unfamiliar

with static control procedures, refer to Guarding Against Electrostatic

Damage, publication 8000-4.5.2.

Step 1 Remove power from the controller.

Step 2 Set the 1769-SM2 module Configuration Mode switch and Operating

Mode (Single/Multi-Drive) switch to appropriate positions. For complete

switch setting details, see the 1769-SM2 module User Manual.

Step 3 Assemble the 1769-SM2 module to the controller. It can be attached to

adjacent controller modules before or after mounting. For mounting

instructions, see Step 4A (Panel Mounting) or Step 4B (DIN Rail

Mounting). To work with a system that is already mounted, see Step 5.

A. Disconnect power.

B. Install the 1769-SM2 module within 4 slots of the power supply.

C. Check that the bus lever (item 1) of the 1769-SM2 module is in the

unlocked (fully right) position.

D. Use the upper and lower tongue-and-groove slots (item 2) to secure the

modules together.

E. Move the 1769-SM2 module back along the tongue-and-groove slots

until the bus connectors (item 3) line up with each other.

F. Use your fingers or a small screwdriver to push the bus lever back

slightly to clear the positioning tab (item 4).

G. Move the 1769-SM2 module’s bus lever fully to the left (item 5) until it

clicks. Ensure it is locked firmly in place.

H. Attach an end cap terminator (item 6) to the last module in the system

by using the tongue-and-groove slots as before.

I. Lock the end cap bus terminator (item 7).

Important: A 1769-ECR or 1769-ECL right or left end cap must be used

to terminate the end cap of the serial communication bus.

ATTENTION: Risk of equipment damage exists. When

attaching the 1769-SM2 module to a Compact I/O system, it is

very important that the bus connectors are securely locked

together to ensure proper electrical connection. Failure to do

this may cause an electrical arc, which can cause personal

injury or equipment damage.

Step 4 Mount the 1769-SM2 module.

Maintain spacing from enclosure walls, wireways, adjacent equipment, etc.

Using Module as a Template

The following procedure enables you to use the assembled modules as a

template for drilling holes in the panel. Due to module mounting hole

tolerance, it is important to follow these steps:

a. On a clean work surface, assemble no more than three modules.

b. Using the assembled modules as a template, carefully mark the

center of all module-mounting holes on the panel.

c. Return the assembled modules to the clean work surface, including

any previously mounted modules.

d. Drill and tap the mounting holes for the recommended M4 or #8

screw.

e. Place the modules back on the panel, and check for proper hole

alignment.

f. Attach the modules to the panel using the mounting screws.

B. DIN Rail Mounting — The 1769-SM2 module can be mounted using

the following DIN rails:

•35 x 7.5 mm (EN 50 022 - 35 x 7.5)

•35 x 15 mm (EN 50 022 - 35 x 15)

Before mounting the module on a DIN rail, close the DIN rail latches.

Press the DIN rail mounting area of the module against the DIN rail.

The latches will momentarily open and lock into place.

Step 5 Replacing the module within a system. The 1769-SM2 module can be

replaced while the system is mounted to a panel (or DIN rail).

A. Remove power.

B. Unplug the communications cable from each port (CH1, CH2, CH3) on

the 1769-SM2 module. Note each drive and the port to which it is

connected.

C. Remove the upper and lower mounting screws from the module (or

open the DIN latches using a flat-blade screwdriver).

D. On the right-side adjacent module, move its bus lever to the right

(unlock) to disconnect it from the module being removed.

E. Gently slide the disconnected 1769-SM2 module forward. If you feel

excessive resistance, make sure that you disconnected the module from

the bus and that you removed both mounting screws (or opened the DIN

latches).

ATTENTION: Risk of equipment damage exists. Remove

power before installing or removing the 1769-SM2 module.

When you install or remove the module with power applied, an

electrical arc may occur. An electrical arc can cause personal

injury or equipment damage by:

•Sending an erroneous signal to your system’s filed devices,

causing unintended machine motion.

•Causing an explosion in a hazardous environment.

Electrical arcing causes excessive wear to contacts on both the

module and its mating connector. Worn contacts may create

electrical resistance.

TIP: It may be necessary to slightly move the module from

front to back to remove it, or in a panel-mounted system, to

loosen the screws of adjacent modules.

F. Before installing the replacement 1769-SM2 module, be sure that the

bus lever on the right-side adjacent module is in the unlocked (fully

right) position.

G. Slide the replacement 1769-SM2 module into the open slot.

H. Connect the 1769-SM2 module and adjacent modules together by

locking (fully left) the bus levers on the 1769-SM2 module and the

right-side adjacent module.

I. Replace the mounting screws (or snap the module onto the DIN rail).

J. Plug the appropriate communications cable into its respective port on

the 1769-SM2 module.

K. Restore 1769-SM2 module configuration using an appropriate

configuration tool.

Step 6 Connect the module to the drive(s).

For information and network wiring examples, see the 1769-SM2 User

Manual.

NOTE: For Single or Multi-Drive mode, there is a maximum cable

distance limit per channel. See the 1769-SM2 User Manual for details.

Step 7 Ground the module.

The 1769-SM2 module is intended to be mounted to a well-grounded

mounting surface such as a metal panel. Additional grounding connections

from the module’s mounting tabs or DIN rail (if used) are not required

unless the mounting surface cannot be grounded. For additional

information, refer to Industrial Automation Wiring and Grounding

Guidelines, publication No. 1770-4.1.

For details on shielded connector and unshielded connector grounding

requirements, see the 1769-SM2 Compact I/O DSI/Modbus Network

Communication User Manual, publication 1769-UM013.

Step 8 Apply power.

A. Apply power to the controller. The status indicators can be viewed on

the front of the 1769-SM2 module after power has been applied.

B. Apply power to the drive(s). When you apply power to the 1769-SM2

module, controller, and network for the first time, the status indicators

should be green after an initialization. If the status indicators go red,

there is a problem. Refer to the “Troubleshooting” chapter in the

1769-SM2 Compact I/O DSI/Modbus Network Communication User

Manual.

Step 9 Read the 1769-SM2 Compact I/O DSI/Modbus Network Communication

User Manual for information to configure and determine how to apply the

network to the host product(s).

ATTENTION: Risk of equipment damage, injury, or death

exists. Unpredictable operation may occur if you fail to verify

that parameter settings are compatible with your application.

Verify that settings are compatible with your application before

applying power to the drive.
