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.

New Features
The controllers contain an RJ-45 connector for the Channel 2 communication port.
The controllers provide additional Channel 2 port configuration and status:
• 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.
Publication 1785-IN063B-EN-P - January 2006
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.

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.
Publication 1785-IN063B-EN-P - January 2006
10 Ethernet PLC-5 Programmable Controllers
To create an email:
1. Create a message instruction similar to the one below.
The destination (to), the reply (from), and the body (text) are stored as strings in elements of separate ASCII string files.
If you want to send an email to a specific recipient when a controller application generates an alarm or reaches a certain condition, program the controller to send the message instruction to the destination of the email.
2. Verify the rung.
3. Click on Setup Screen.
A dialog appears like the one below.

If you connect or disconnect any communications 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.
The local programming terminal port (circular mini-DIN style programming terminal connection) is intended for temporary use only and must not be connected or disconnected unless the area is assured to be nonhazardous.

- controller detects a runtime error
- an I/O chassis backplane fault occurs
- you select program or test mode
- you set a status file bit to reset a local rack
(2) If an EEPROM module is not installed and controller memory is valid, the controller's PROC LED indicator blinks,
and the processor sets S:11/9, bit 9 in the major fault status word. To clear this fault, change the controller from
program mode to run mode and back to program mode.
(3) If the controller's keyswitch is set in REMote, the controller enters remote RUN after it powers up and has its
memory updated by the EEPROM module.
(4) A processor fault (solid red PROC LED) occurs if processor memory is not valid.
(5) You cannot clear processor memory when this switch is on.
