Publication 1756-IN572E-EN-P – March 2004

Overview

The 3, 8, or 16 Axis SERCOS interface module serves as a link between the

ControlLogix platform and intelligent drives. The communication link

between the module and the drive(s) is via IEC/EN 61491 SErial Real-time

COmmunication System (SERCOS) using fiber optic medium. Fiber optics

assures reliable high speed data transmission with excellent noise immunity,

improved performance, and elimination of interconnect wiring.

SERCOS is a real-time optical serial interface between the control unit and its

associated drives to transmit periodic and non-periodic data. Its topology is

that of a ring with one master and multiple slaves (axes). The 3, 8 or 16 Axis

SERCOS interface module serves as the interface between one ControlLogix

processor and 1 to 3 axes for the 1756-M03SE, 1 to 8 axes for the

1756-M08SE, and 1 to 16 axes for the 1756-M16SE operating in either

position, velocity, or torque mode. The module has a programmable ring

Cycle Period of 0.5ms, 1ms or 2ms depending on the number of axes and a

ring Data Rate of 4 Mbaud or 8 Mbaud. The module is designed to meet the

Control and Information Protocol (CIP) common specification.

Preventing Electrostatic Discharge

ATTENTION This equipment is sensitive to electrostatic discharge,

which can cause internal damage and affect normal

operation. Follow these guidelines when you handle

this equipment:

•Touch a grounded object to discharge potential

static.

•Wear an approved grounding wriststrap.

•Do not touch connectors or pins on component

boards.

•Do not touch circuit components inside the

equipment.

•If available, use a static-safe workstation.

•When not in use, store the equipment in

appropriate static-safe packaging.

3, 8, or 16 Axis SERCOS interface Module 5

Publication 1756-IN572E-EN-P – March 2004

Removing and Inserting Under Power (RIUP)

This module is designed so you can remove and insert it under backplane

power and field-side power.

Repeated electrical arcing causes wear to contacts on both the module and its

mating connector. Worn contacts may create electrical resistance that can

affect module operation.

This equipment is classified as open equipment and must be installed

(mounted) in an enclosure during operation as a means of providing safety

protection.

Determining the Power Requirements

This module receives power from the 1756 chassis power supply and requires

two sources of power: 760 mA at 5.1V and 2.5 mA at 24V from the

backplane. Add this current to the requirements of all other modules in this

chassis to prevent overloading the backplane power supply.

Identifying Module Components

The following diagrams provide two views of the module. The first diagram is

a front view which shows the position and function of the LEDs and the

icons for the receiver and transmitter. The second diagram is a side view

which shows the position of the transmitter and receiver connectors. (The

1756-M03SE and the 1756-M16SE look identical to the 1756-M08SE.)

WARNING When you insert or remove the module while backplane

power is on, an electrical arc can occur. This could cause

an explosion in hazardous location installations. Be sure

that power is removed or the area is nonhazardous

before proceeding.

cable connector assembly fits over the module connector and is screwed on

finger tight. Make sure that you remove the protector end caps before

The Module’s Product Label

The following figure shows the product label that is affixed to the side of the

1756-M03SE, 1756-M08SE, and 1756-M16SE modules. The three modules

look very much alike and checking the label carefully is the only way to be sure

that you have the correct module. Pay particular attention to the CAT. NO.

SERIES field on the label. This field indicates whether you have a

1756-M03SE, 1756-M08SE, or 1756-M16SE module and also the series of

the module. The label contains additional information about the module and

should be thoroughly checked prior to installation to ensure that the product

matches your expectations.

Fiber Optic Transmission

The fiber optic transmitter for the SERCOS interface 3, 8, or 16 Axis module

uses a 650nm wavelength. This produces a visible light from the port and is a

determinant in factoring maximum cable lengths. The high light output lets

you use both plastic optical fiber (POF) and Hard Clad Silica (HCS®) cables.

The fiber optics used with the 1756-M03SE, 1756-M08SE and 1756-M16SE

modules are rated Class 1 for IEC Laser (LED) Safety Classification. Be aware

that under certain conditions, viewing the optical port may expose the eye to

hazard. Under most viewing conditions, there is no eye hazard.

ATTENTION When viewed under some conditions, the optical port

may expose the eye beyond the maximum permissible

exposure recommended in ANSI Z136.2, 1993.
