Date PLC / CPU Canonical profile Transport Verified scope Limitations Record
2026-05-03 MELSEC iQ-F / FX5UC-32MT/D melsec:iq-f TCP 1025, UDP 1027 Device-range sample validation and profile-specific address checks. iQ-F X/Y text notation is octal; DX/DY are not valid for this profile. Retained maintainer note
2026-05-03 MELSEC iQ-R / R08CPU melsec:iq-r TCP 1025, UDP 1027 Device-range sample validation, all-device checker coverage, and bit-block checks. Unsupported S entries are recorded in the validation note. Retained maintainer note
2026-05-03 MELSEC iQ-L / L16HCPU melsec:iq-l TCP 1025, UDP 1027 Device-range sample validation and live stress validation. iQ-L keeps its own profile while using iQ-R-equivalent address grammar. Retained maintainer note
2026-05-03 MELSEC LCPU melsec:lcpu TCP 1025, UDP 1027 Device-range sample validation. Profile-limited legacy 3E behavior is recorded in the validation note. Retained maintainer note
2026-05-15 MELSEC Q12HCPU melsec:qcpu TCP 1025 Runtime range validation for legacy 3E QCPU routing. Z, ZR, and R ranges are target-resolved and documented in the validation note. Retained maintainer note
2026-05-15 MELSEC Q26UDEHCPU melsec:qnu TCP 1025 Runtime range validation for QnU routing. Target-specific runtime limits are documented in the validation note. Retained maintainer note
2026-05-03 / 2026-05-15 MELSEC Q06UDVCPU melsec:qnudv TCP 1025 Device-range sample validation and runtime range validation. Target-specific runtime limits are documented in the validation notes. Retained maintainer note

Update this page when a new live-device validation result becomes the public summary. Keep detailed raw notes as maintainer records and keep this page focused on the public summary.
