1734-ADNX Quick Start
What’s In This Appendix?
In this Quick Start, you will learn how to use the 1734-ADNX with a
ControlLogix system on DeviceNet. You will also use one of the
1734-ADNX’s features (Auto Start Mode) in an exercise to
automatically configure devices on its Subnet
.
When you complete this quick start you will be familiar with:
•
The 1734-ADNX as an adapter on the ControlLogix primary
DeviceNet network and as a scanner on the DeviceNet
expansion Subnet.
•
Configuring the 1734-ADNX with POINT I/O and additional
devices on its Subnet.
•
Using and applying the correct termination of the 1734-ADNX’s
Subnet.
•
Using the 1734-ADNX to expand the length of a DeviceNet
system
•
Using the 1734-ADNX to implement a second baudrate for
Subnet devices.
Assumptions
A ControlLogix DeviceNet system already exists to which you are
going to add new devices without modifying the existing system’s
architecture. You are going to expand the length of the system beyond
its maximum specification and add new devices which can operate at
a different baudrate than the existing system.
The existing system attributes include:
•
ControlLogix processor in a Logix chassis of 8 or more slots.
•
1756-ENBT (EtherNet/IP) in the Logix chassis.
•
Configured to 125 Kbaud with thin trunk (max distance is 100m
(328 ft) (ControlLogix chassis may be connected on any
DeviceNet network).
•
ControlLogix Processor with a 1756-DNB (DeviceNet) in slot 8
(slot 8 was picked for this example. This can be any slot.)
