Every I/O module in a Logix 5000 control system must be owned by a
controller, also known as the owner-controller. When a Compact 5000 I/O
digital module is used in a Logix 5000 control system, the owner-controller
performs the following:

5069-OF8 • Stores configuration data for every module that it owns.
• Can reside in a location that differs from the Compact 5000 I/O
digital modules.
• Sends the I/O module configuration data to define module behavior
and begin operation in the control system.

Each Compact 5000 I/O digital module must continuously maintain
communication with its owner-controller during normal operation.
Typically, each I/O module in a system has only one owner-controller. Output
modules are limited to one owner-controller.

Typically only one owner-controller is connected to a Compact 5000 I/O
digital input module. However, multiple Logix 5000 controllers can connect to
Compact 5000 I/O digital input modules as owner-controllers.
In this case, the following conditions must exist:
• The controllers maintain the same configuration.
• The configuration in each controller uses a Data connection to the
input module.
• The first controller to make a connection to the input module is the
only controller that can change the connection. Therefore, it is 'owns'
the module configuration.
IMPORTANT If the controller that owns the module configuration changes the

configuration, the other controllers are not notified of the changes.
