Ownership I/O modules in a ControlLogix system can be owned by a Logix5000™ controller. An owner-controller fulfills these functions:
• Stores configuration data for every module that it owns
• Sends I/O modules configuration data to define module behavior and begin module operation with the control system
• Resides in a local or remote chassis in regard to the I/O module position
Each ControlLogix I/O module must continuously maintain communication with its owner-controller to operate normally.
Typically, each module in the system has only one owner-controller. Input modules can have more than one owner-controller. Output modules, however, are limited to a single owner-controller.

Internal Module Operation ControlLogix I/O modules experience signal propagation delays that must be accounted for during operation. Some of these delays are user-configurable, and some are inherent to the module hardware.
For example, there is a small delay, typically less than 1 ms, between when a signal is applied at the RTB of a ControlLogix input module and when a signal is sent to the system over the backplane. This time reflects a filter time of 0 ms for a DC input.
This section offers an explanation of the time limitations with ControlLogix I/O modules.

Input Modules
As shown in the illustration, ControlLogix input modules receive a signal at the RTB and process it internally through hardware, filters, and an ASIC scan before sending a signal to the backplane via the requested packet interval (RPI) or at a Change of State (COS) occurrence. The RPI is a configured interval of time that determines when module data is sent to the controller.
