Micro PLC migration
MicroLogix 1000, 1100, 1200 and 1400 to Micro800 migration
Star Automations migrates MicroLogix controllers to Micro800 (programmed in Connected Components Workbench) or, for the MicroLogix 1500, to CompactLogix. We review the program, I/O and communications, rebuild the logic and test it before cutover, and supply MicroLogix spares while you plan.
Typical migration paths
The right target depends on your I/O count, networks, performance needs and budget. We confirm the target during the audit — the table shows the usual direction, not a fixed rule.
| Legacy | Typical target | What to watch |
|---|---|---|
| MicroLogix 1000 / 1100 / 1200 | Micro800 (Micro820 / 830 / 850) | Different software: Connected Components Workbench |
| MicroLogix 1400 | Micro800 | Check I/O count and Ethernet needs |
| MicroLogix 1500 | CompactLogix | Larger system; Studio 5000 |
What needs care in this migration
Software change
Micro800 uses Connected Components Workbench and IEC 61131-3 languages, not RSLogix 500. Logic is rebuilt and tested, not just copied.
I/O and ports
We compare embedded I/O, expansion modules and serial or Ethernet ports so nothing is lost.
Serial protocols
If you use DF1 or Modbus on serial ports, we confirm the same function on the new controller.
Our migration process
- Migration readiness audit: inventory of hardware, firmware, networks, programs and spares
- Back up and document the running system before anything is touched
- Design the target architecture and I/O mapping; agree scope and the cutover approach
- Convert and rebuild the program and HMI, with every conversion warning reviewed by hand
- Test in stages: simulation, panel factory test where panels are built, then site testing
- Cutover with a rollback plan, then handover documentation
What we need from you: Program backups (or access to the running processor); Electrical drawings and the I/O list, if available; Network layout and device list; Photos of nameplates, panels and wiring; Your shutdown windows and any safety requirements.
