Determine When Data Is
Updated
ControlLogix controllers update date asynchronously with the
execution of logic. Use this flowchart to determine when a producer,
such as a controller, input module, or bridge module, will send data.

Data is sent to the backplane at the
RPI.
Remote or Local?

Data is sent to the backplane at the RPI
and at the end of every task.
Data is sent to the backplane at the RPI
and at the change of a specified point.
Data is sent to the backplane at
the RTS and RPI.
Data is sent to the backplane
at the RTS.

Over a ControlNet network, remote data is sent at the actual packet
interval.
•
Over an EtherNet/IP network, remote data is usually sent close to
the RPI.
