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:

•Industrial Automation Wiring and Grounding Guidelines, for additional installation requirements, Allen-Bradley publication 1770-4.1.

•NEMA Standards publication 250 and IEC 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, 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.

About the Module

The module provides EtherNet/IP connectivity. Use the tap to support linear, star, and device-level ring (DLR) topologies. The module is configured by default to support linear and star topologies. When setting up a DLR, follow the steps in the Use the Module in a Device-level Ring (DLR) Network section on page 15 to avoid adversely impacting your network.

Refer to the EtherNet/IP Ring Topology Application Guide, publication ENET-AP005, for information on setting up EtherNet/IP network topologies.

1756-EN2TR	RSLinx Classic	2.55 or later
	RSLogix 5000	17.0x (supports revision 2 of module firmware only)
		If you are using version 17.01 of RSLogix 5000 software, you need to download the
		add-on-profile. Download it from
		http://www.rockwellautomation.com/support/controlflash/LogixProfiler.asp
		or

Set the Network Address

The module is shipped with the rotary switches set to 999 and BOOTP enabled. You can set the network Internet Protocol (IP) address three ways.

•Use the rotary switches on the top of the module.

•Use a BOOTP server or Dynamic Host Configuration Protocol (DHCP) server.

•Use Rockwell Automation RSLinx Classic or RSLogix 5000 software.

Use the Rotary Switches

		3

The module reads the rotary switches first to determine if they are set to a valid number for the last portion of the IP address. Valid numbers range from 001…254.

When the switches are set to a valid number, the module’s IP address is 192.168.1.xxx (where xxx represents the number set on the switches). The module’s subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0.

The module does not have a host name assigned, nor does it use any Domain Name System when using the rotary switch settings.

1.To reset the module to its initial out-of-the-box settings, reset the switches to 888 and cycle power.

IMPORTANT	Do not use the 888 switch setting during normal module operation.

2.After cycling power with the switches set to 888, remove the module and set the switches to their final value.

The software configuration determines the IP address when you set the rotary switches to:

•a value other than 888.

•the valid IP address values 001…254.
