2 Rockwell Automation Publication 1734-UM018D-EN-E - September 2017
Chapter 1 Overview of the 1734 POINT I/O EtherNet/IP Adapter
Some of the module’s features are as follows:
• EtherNet/IP messages encapsulated within standard TCP/UDP/IP
protocol
• Common application layer with ControlNet and DeviceNet networks
• Interfacing via Category 5 rated twisted pair cable
• Half/full duplex 10 Mbit or 100 Mbit operation
• DIN rail mounting
• Communication to and from other POINT I/O modules on the same
DIN rail
• Communication supported by RSLinx software
• IP address assigned via standard DHCP tools
• I/O configuration via RSLogix 5000 or Logix Designer software
• No network scheduling required
• No routing tables required
• Support of connections from multiple controllers simultaneously
You must use RSLogix 5000 to configure these features. For more details on
configuration, see Configuration Requirements
in Chapter 3.
What the Adapter Does
The I/O adapters perform the following primary tasks:
• Control of real-time I/O data (also known as implicit messaging) - the
adapter serves as a bridge between I/O modules and the network
• Support of messaging data for configuration and programming
information (also known as explicit messaging)
• Support of Output hold in all output modules during Program mode and
Fault mode. Note that the option is not available for Program Download
mode.
