Input Module Features Chapter 3
Data Transfer at RPI or
Change of State
Compact 5000 I/O digital input modules always send data at the RPI, but they
send data at a change of state only if the COS feature is enabled.
The table describes the two ways a module sends data to the owner-controller.
You set the RPI on the Connection page of the Module Properties dialog box
in the Logix Designer application.

Method Description
RPI A user-defined rate at which the module updates the information that is sent to its
owner-controller.
COS Configurable feature that, when enabled, instructs the module to update its owner-controller
with new data whenever a specified input point transitions from On to Off and Off to On. The
data is sent at the RPI rate when there is no change of state. By default, this setting is always
enabled for input modules.
