Why migrate
MicroLogix is end-of-life. RSLogix 500 is no longer actively developed.
Where to go
- MicroLogix 1100/1400 → Micro870 or CompactLogix 5380.

Conversion
Use Logix Designer import or the Migration Toolkit. Refactor:
- Data-table addresses → tag-based
- STI/PII interrupts → periodic tasks
- F8 floats → REAL tags
