Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc., is prohibited.

ATTENTION
			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 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.

ATTENTION				POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated
				yellow-chromate steel DIN rail to assure proper grounding. The use of other
				DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize,
				or are poor conductors, can result in improper or intermittent grounding.
				Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and
				use end-anchors appropriately.
				To comply with the CE Low Voltage Directive (LVD), this equipment must be
ATTENTION
				powered from a Safety Extra Low Voltage (SELV) or Protected Extra Low
				Voltage (PELV) compliant source
				Do not remove or replace an Adapter Module while power is applied.
ATTENTION
				Interruption of the backplane can result in unintentional operation or machine
				motion.
				When you insert or remove the module while backplane power is on, an
WARNING
				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.

About the Adapter

Read this publication for information about the POINT I/O Ethernet adapter, a communications adapter for POINT I/O modules.

This adapter is for the POINT I/O backplane that provides connectivity to an Ethernet network with two RJ-45 connectors for 2 port pass-through to support daisy chain or ring, and the existing star and tree network topologies.

POINT I/O 2 Port Ethernet Adapter 9

Before You Begin

To effectively use your adapter, note the following considerations.

Determine Compatibility

RSLogix 5000 version 17 or greater must be used for the 1734-AENTR Add-on Profile. The 1734-AENTR adapters will accept I/O connections with the electronic keying for the 1734-AENT. This allows the 1734-AENTR adapter to be used in a daisy-chain topology with the 1734-AENT profile used for the 1734-AENTR.

If using the adapter with a 1756-ENBT module, 1768-ENBT module or an L3xE processor, use the following required firmware versions for these bridge modules:

•1756-ENBT firmware version 4.5 or greater

•1768-ENBT firmware version 2.1 or greater

•L3xE processor firmware version 17 or greater

If you use the BootP utility to assign IP addresses to the adapter, use version 2.3.2 or greater.

Understand Messaging

Class 3 (Explicit Message) requests through the 1734-AENTR adapter to a specific POINT I/O module do not always receive a response from the I/O modules. In the case where the I/O module does not reply to the request, the adapter responds with an error code indicating a time-out.

Establish I/O Connections

When you start a POINT I/O system and establish I/O connections, the outputs transition to the Idle state, applying Idle state data before going to Run mode. This occurs even when the controller making the connection is already in Run mode.
