Using I/O Messaging
Chapter 6 provides information and examples that explain how to
use a ControlLogix controller to send I/O Messaging to control,
configure, and monitor an SP600, GV6000 or LiquiFlo 2.0 drive.
Important: At the time of publication, only ControlLogix
controllers are able to transmit I/O data over an
EtherNet/IP network. PLC-5 and SLC controllers
cannot transmit EtherNet/IP I/O data. However, these
controllers can perform control using explicit
messaging to the Register object and PCCC N41 and
N42 files.
6.1 About I/O Messaging
On EtherNet/IP networks, I/O messaging is used to transfer the data
that controls the Reliance Electric drive and sets its reference. I/O
can also be used to transfer data to and from Datalinks in Reliance
Electric drives.
The module provides the following options for configuring and using
I/O:
• The size of I/O can be configured by enabling or disabling the
Logic Command/Reference and Datalinks.
• A Master-Slave hierarchy or a Peer-to-Peer hierarchy can be set
up.
