ControlLogix DeviceNet Scanner Module 5
Publication 1756-IN566D-EN-P - June 2008
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
publication 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 Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.
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.
Besides this publication, see:
•Industrial Automation Wiring and Grounding Guidelines, for additional
installation requirements, Allen-Bradley publication 1770-4.1.
•NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure.

About this Publication
Use this publication as a guide to install the module. This publication
describes hardware installation only. For configuration information, refer to
the DeviceNet Modules in Logix5000 Systems User Manual, publication
DNET-UM004.
The following information applies when
operating this equipment in hazardous
locations.
Informations sur l’utilisation de cet
équipement en environnements dangereux.
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.
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 combinésdansun 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.
WARNING EXPLOSION HAZARD -
• Do not disconnect equipment unless
power has been removed or the

Set the Communication Rate
The 1756-DNB scanner module supports the following DeviceNet network
communication rates:
•125 Kbps
•250 Kbps
•500 Kbps
The factory default setting is 125 Kbps.
Change the communication rate by setting the rotary switch or
commissioning the 1756-DNB scanner module in RSNetWorx for DeviceNet
software.
Use the switch to select a specific communication rate. When the switch is set
to 3...9 (except for 888), you can configure the communication rate with
RSNetWorx for DeviceNet software. When all three switches are set to 8, the
1756-DNB scanner module will reset to factory default settings at powerup.
See Restore the Factory Default Settings on page 15 for more information.
See the following table for switch settings.
ATTENTION Do not change the communication rate on an active network. Unpredictable
operation may result. In addition, the new communication rate does not take
effect until you cycle power to the 1756-DNB scanner module.
