I've not come across a CPU-less option for migrating from a SLC500.
Goals: Move PLC controlled equipment to DCS.
Requirements:
-minimal downtime (no rewire)
-remove SLC CPU
-reuse existing SLC IO modules
Every communication option i've come across for the SLC series involves using the CPU as an IO multiplexer.
Can the SLC I/O become remote I/O over Ethernet/IP? If so, you can use a QuickPanel + configured with PAC Machine Edition.
