EtherNet/IP Embedded Switch TechnologyLinear and Device-level Ring TopologiesCatalog Numbers 1756-EN2TR, 1756-EN3TR, 1783-ETAP, 1783-ETAP1F, 1783-ETAP2F, 1734-AENTR, 1738-AENTR, 1732EApplication GuideImportant User InformationSolid 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://www.rockwellautomation.com/literature/) 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.Throughout this manual, when necessary, we use notes to make you aware of safety considerations.Allen-Bradley, ArmorBlock, ArmorPoint, CompactLogix, ControlLogix, POINT I/O, Rockwell Automation, RSLinx, RSLogix, Stratix 2000, Stratix 6000, Stratix 8000, Stratix 8300, and TechConnect are trademarks of Rockwell Automation, Inc.Trademarks not belonging to Rockwell Automation are property of their respective companies.WARNINGIdentifies information about practices or circumstances that can cause an explosion in a hazardous environment, which may lead to personal injury or death, property damage, or economic loss.IMPORTANTIdentifies information that is critical for successful application and understanding of the product.ATTENTIONIdentifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss. Attentions help you identify a hazard, avoid a hazard, and recognize the consequenceSHOCK HAZARDLabels may be on or inside the equipment, for example, a drive or motor, to alert people that dangerous voltage may be present.BURN HAZARDLabels may be on or inside the equipment, for example, a drive or motor, to alert people that surfaces may reach dangerous temperatures.3Publication ENET-AP005D-EN-P - August 20113Summary of ChangesIntroductionThis release of this document contains new and updated information. To find new and updated information, look for change bars, as shown next to this paragraph.Updated InformationThe document has been changed to provide the most accurate and common topologies currently available with a DLR application.
