Planning to Use Your ControlNet Adapter
Module
Chapter Objectives This chapter explains how the adapter operates on ControlNet and
provides information to assist in configuring your system. This includes:
•
compatible 1746 and 1747 I/O modules
•
overview of adapter operation
•
software requirements
•
rack and module connections
•
optimizing SLC ControlNet Adapter connections
•
module keying
•
output operation during Fault and Idle modes
•
understanding ControlNet I/O
•
scheduled Data-Transfer connections on a ControlNet network
Compatible 1746 and
1747 I/O Modules The majority of 1746 and 1747 discrete, analog and specialty modules
are compatible with the 1747-ACN15 and 1747-ACNR15 adapters.
Exceptions include any modules that require G file configuration. These
include:
•
1747-SN Remote I/O Scanner module
•
1747-BSN Back-Up Remote I/O Scanner module
•
1746-QV Open Loop Velocity Control module
•
1203-SM1 Scanport module (Class 4 operation) (This module is
compatible when configured for class 1 operation.)
•
1747-SCNR ControlNet Scanner module (G files not required,
however, this module is not supported by the 1747-ACN15/
ACNR15)
A small number of 1746 modules are currently not supported by the
adapter due to lack of an EDS (electronic data sheet) file. These
modules will be supported once EDS development is completed. A
complete list of compatible 1746 and 1747 modules can be found on the
Allen-Bradley Technical Support Knowledge Base at:
