Environment and Enclosure

ATTENTION: This equipment is intended for use in a

Pollution Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC 60664-1), at
altitudes up to 2000 m (6562 ft) without derating.

This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR 11. Without appropriate
precautions, there may be difficulties with electromagnetic
compatibility in residential and other environments due to
conducted and radiated disturbances.

This equipment is supplied as open-type equipment. It must be
mounted within an enclosure that is suitably designed for those
specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from
accessibility to live parts. The enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of
flame, complying with a flame spread rating of 5VA, V2, V1, V0
(or equivalent) if non-metallic. The interior of the enclosure must
be accessible only by the use of a tool. Subsequent sections of
this publication may contain additional information regarding
specific enclosure type ratings that are required to comply with
certain product safety certifications.

In addition to this publication, see the following:

Prevent 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.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging

when not in use.

ATTENTION: If this equipment is used in a manner not specified
by the manufacturer, the protection provided by the equipment may
be impaired.

ControlLogix Remote I/O (RIO) Module 5

Removal and Insertion Under Power

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. Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating connector. Worn
contacts may create electrical resistance that can affect module
operation.

Multi-point Network Communication Connections

WARNING: If you connect or disconnect the communication cable

with power applied to this module or any device on the network, 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.

North American Hazardous Location Approval

The following information applies
when operating this equipment in
hazardous locations:

Products marked ‘CL I, DIV 2, GP A, B, C, D’ are
suitable for use in Class I Division 2 Groups A, B,
C, D, Hazardous Locations and nonhazardous
locations only. Each product is supplied with
markings on the rating nameplate indicating the
hazardous location temperature code. When
combining products within a system, the most
adverse temperature code (lowest ‘T’ number) may
be used to help determine the overall temperature
code of the system. Combinations of equipment in
your system are subject to investigation by the
local Authority Having Jurisdiction at the time of
installation.

WARNING:
EXPLOSION HAZARD –

•Do not disconnect equipment
unless power has been
removed or the area is known
to be nonhazardous.

• Do not disconnect connections
to this equipment unless
power has been removed or
the area is known to be
nonhazardous.Secure any
external connections that mate
to this equipment by using
screws, sliding latches,
threaded connectors, or other
means provided with this
product.

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

•If this product contains
batteries, they must only be
changed in an area known to
be nonhazardous.

Informations sur l’utilisation de cet
équipement en environnements
dangereux:

Les produits marqués ‘CL I, DIV 2, GP A, B, C, D’ ne
conviennent qu'à une utilisation en environnements
de Classe I Division 2 Groupes A, B, C, D dangereux
et non dangereux. Chaque produit est livré avec des
marquages sur sa plaque d'identification qui
indiquent le code de température pour les
environnements dangereux. Lorsque plusieurs
produits sont combinés dans un système, le code de
température le plus défavorable (code de
température le plus faible) peut être utilisé pour
déterminer le code de température global du
système. Les combinaisons d'équipements dans le
système sont sujettes à inspection par les autorités
locales qualifiées au moment de l'installation.

ControlLogix Remote I/O (RIO) Module 7

IMPORTANT

About the Module

The ControlLogix 1756-RIO module connects a ControlLogix processor to a
remote I/O network.

The module can act as a scanner or as an adapter on the network. For additional
information, see publication 1756-UM534

This module is shipped in scanner mode, with a blank
configuration.

.

1756-RIO Module as a Scanner

As a scanner, with one remote I/O channel, the 1756-RIO module scans I/O on
a remote I/O network.

The module supports the following:

• All remote I/O baud rates: 57.6, 115.2, 230.4 Kbaud

• Rack numbers from 0…76 octal

• All combinations of partial racks

• Up to 32 physical adapters

To support 32 physical adapters, you must use an 82  resistor; 150 
resistors allow only 16 adapters.

The module can update block transfers (BTs) automatically via the 1756-RIO
module or can be controlled by the ControlLogix controller. It transfers all I/O
via produced/consumed connections over the backplane to the controller.

• Block transfers at all possible locations

monitor an existing scanner. The module supports the following features:

• Has one remote I/O channel

• Emulates one or more racks

• All remote I/O baud rates: 57.6, 115.2, 230.4 Kbaud

• Rack numbers from 0…76 octal

• All combinations of partial racks

• Block transfers at all possible locations

• Can monitor I/O on a network with an existing remote I/O scanner

(Monitor Mode)

• Transfers all I/O to the controller via produced/consumed connections

over the backplane to the controller.

The module firmware can be updated using the Windows utilities
software supplied with the module.
