Chapter 1 About the Adapters
When you first apply power, we expect that all but one module on the backplane
exhibits a solid red Module Status LED.
One by one the adapter resets these modules and addresses them appropriately.
The amount of time that this operation takes is proportional to the size of your I/
O system.
Adapter Features
Features of the adapters include:
•
Use of 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 for 1734-AENTR adapter/Wall or panel mounting for
1738-AENTR adapter
•
Communication to and from other I/O modules on the same DIN rail for
1734-AENTR adapter/Communication to and from other I/O modules
in the chassis for 1738-AENTR adapter
•
Communication supported by RSLinx software
•
IP address assigned via standard BootP or DHCP tools
•
I/O configuration via RSLogix 5000 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
.
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)
