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.

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.

The end of the cable is inserted into the appropriate connector of the
1756M03SE, 1756-M08SE, or 1756-M16SE. The threaded portion of the
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.
