Rockwell's migration path
- Rockwell's path off the SLC 500 is CompactLogix 5380 controllers with Compact 5000 I/O. (source)
- Rockwell's SLC 500 Hardware Migration reference manual (publication 1746-RM003) lists a recommended CompactLogix controller for each SLC processor and replacement modules for the 1746 I/O, so it is the place to look up the replacement for one catalog number. (source)
- For the program, Rockwell's SLC to CompactLogix Programming Migration guide (publication 5069-AP001) covers converting an RSLogix 500 project. (source)
- Rockwell's 1492 I/O wiring systems connect the new I/O to the existing field wiring, so the wires can stay where they are. (source)
