In short
MicroLogix 1000/1100/1200/1400/1500 to Micro800 or CompactLogix.
Why migrate
MicroLogix is end-of-life. RSLogix 500 is no longer actively developed.
Where to go
- MicroLogix 1100/1400 → Micro870 or CompactLogix 5380.
- MicroLogix 1000/1200/1500 → Micro820/850/870 per I/O count.
Conversion
Use Logix Designer import or the Migration Toolkit. Refactor:
- Data-table addresses → tag-based
- STI/PII interrupts → periodic tasks
- F8 floats → REAL tags
