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.
