Environment and Enclosure

Ethernet PLC-5 Programmable Controllers 3

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 meters 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 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,

Allen-Bradley publication 1770-4.1, for additional
installation requirements.

– NEMA Standards publication 250 and IEC publication

60529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure.

Prevent Electrostatic Discharge

ATTENTION

This equipment is sensitive to electrostatic discharge that 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 wrist strap.

• 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.

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.

EXPLOSION HAZARD

WARNING

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

• BOOTP, DHCP, or Static entry of IP address

• Auto Negotiate speed selection

• Full/Half Duplex port setting

• 10/100 speed selection

• Email client functionality

• Enable/Disable HTTP Web Server

• Enable/Disable SNMP functionality

To see or activate the new configuration and status features:

1. Open or create a project in RSLogix 5 software, version 7.1 or later.

2. Click on the Channel Configuration menu.

You see the Edit Channel Properties menu.

3. Click on the Channel 2 tab.

BOOTP, DHCP, or Static Entry of IP Address

As shown in the following screen capture, you can select between a static or
dynamic network configuration.

• The default is Dynamic Network Configuration Type and
Use BOOTP to obtain network configuration.

• If you choose a dynamic network configuration, you can change the
default BOOTP to DHCP.

• If you choose a static network configuration type, you must enter the IP
address.

Publication 1785-IN063B-EN-P - January 2006

8 Ethernet PLC-5 Programmable Controllers

Similarly, if you have a dynamic network configuration, DHCP or BOOTP
assigns the controller’s hostname. With a static configuration, you assign the
hostname.

When you create a hostname, consider these naming conventions.

• The hostname can be a text string up to 24 characters.

• The hostname can contain alpha (A to Z) numeric (0 to 9) and may

contain a period and minus sign.

• The first character must be an alpha character.

• The last character must not be a minus sign.

• You cannot use blank spaces or space characters.

• The hostname is not case-sensitive.

Auto Negotiate Speed Selection

In the Edit Channel 2 properties box, you can either leave the Auto Negotiate
box unchecked, which forces the port setting to a particular speed and duplex
port setting, or you may check the Auto Negotiate box, which lets the
controller negotiate a speed and duplex port setting.

If you check Auto Negotiate, the port setting lets you select the range of speed
and duplex settings that the controller negotiates. The default port setting with
Auto Negotiate checked is 10/100 Mbps Full Duplex/Half Duplex, which lets
the controller negotiate any of it’s four available settings. The following table
lists the order of negotiation for each setting.

The unchecked Auto Negotiate box and corresponding port settings are
shown below.

The checked Auto Negotiate box and corresponding port settings are shown

Email Client Functionality

The controller is an email client that sends an email triggered by a message
instruction via a mail relay server. The controller uses standard SMTP protocol
to forward the email to the relay server. The controller does not receive email.

You must enter the SMTP Server’s IP address into the text box as shown in the
following dialog.

The controller supports login authentication. If you want the controller to
authenticate to the SMTP server, check the SMTP authentication box. If you
select authentication, you must also use a username and password for each
email.
