I have a processor and Logic Manager Module with I/O in a rack. How will the CLX-422-IPC get the I/O data from this rack?

The Logic Manager gathers the data from the I/O and processor via a UCN cell-level network.  The LM does not talk directly on the I/O network.

The standard migration path for the CLX-422-IPC module eventually eliminates the entirecontroller rack, including LM.

If the data from the LM is used in a wider Distributed Controlarchitecture, it requires pushing the control data up control layers to the ControlLogix processor.

The CLX-422-IPC Gateway replaces a Honeywell SLM 621-9939 scanner module and communicates
to the I/O racks through the 621-9940 Serial I/O module.
