  • Preserve Ethernet, RS-232, and RS-485 network settings.

  • Confirm input commons and relay output commons before reconnecting field wiring.

  • Verify high-speed input assignments where counters or pulse-catch functions are used.

  • Restore the RSLogix 500 project and verify firmware compatibility.

  • Check all 20 inputs and 12 relay outputs before returning the machine to service.

Replacement Notes

  • Match Series C where the installed machine requires the same hardware revision.

  • Confirm firmware revision 21 against the existing RSLogix project before replacement.

  • The 1766-L32BWA does not include embedded analog I/O.

  • Do not confuse it with the 1766-L32BWAA, which includes embedded analog channels.
