Chapter 2 High-speed Analog I/O Operation in the ControlLogix System
Ownership and Connections Every high-speed analog I/O module in the ControlLogix system must be owned
by a ControlLogix controller. This owner-controller stores configuration data for
the module and can be local or remote in reference to the module’s position. The
owner-controller sends the high-speed analog I/O module configuration data to
define the module’s behavior and begin operation.
The ControlLogix high-speed analog I/O module is limited to a single owner
and must continuously maintain communication with the owner to operate
normally.
ControlLogix input modules allow multiple owner-controllers that each store the
module’s configuration data. The high-speed analog I/O module, however, also
has outputs and cannot support multiple owner-controllers. Other controllers
can make listen-only connections to the module, though. For more information
on listen-only connections, see
page 22 .
Configure the Module The I/O configuration portion of the Studio 5000 Logix Designer application
generates the configuration data for each high-speed analog I/O module in the
control system.
With the configuration dialog boxes in the Logix Designer application, you can
configure the inputs and outputs of a high-speed analog module at the same time.
Configuration data is transferred to the owner-controller during the program
download and subsequently transferred to the appropriate modules.
Follow these guidelines when configuring high-speed analog I/O modules.
1. Configure all modules for the controller by using the software.
2. Download configuration information to the controller.
3. Go online with your Logix Designer project to begin operation.
For more information on how to use the software to configure the module, see
Chapter 5 .
