Latest communication verification

This page keeps the current public summary only. Older detailed notes are not kept in the public documentation set.

Current Retained Summary

  • current Flow Library baseline checked for release notes: 0.2.3
  • current release-prep target: 0.2.12
  • verified PLC models: FX5UC-32MT/D, Q06UDVCPU, R08CPU
  • verified transports: TCP, UDP
  • verified public nodes: slmp-connection, slmp-read, slmp-write
  • retained first-run smoke path: slmp-basic-read-write.json
  • 2026-05-01 iQ-R live check: R08CPU at 192.168.250.100:1025 over TCP returned LCS10=false and LCC10=false through readNamed
  • 2026-05-02 release-prep docs align the Node-RED matrix flow with one-click run-all read/write, status-lamp feedback, JSONL logging, plcProfile result records, and PLC-type-unsupported SKIPPED records

Confirmed Public Register Scope

  • bit devices: SM, X, Y, M, L, F, V, B, TS, TC, LTS, LTC, STS, STC, LSTS, LSTC, CS, CC, LCS, LCC, SB, DX, DY
  • word devices: SD, D, W, TN, LTN, STN, LSTN, CN, LCN, SW, Z, LZ, R, ZR, RD
  • typed forms: :S, :D, :L, :F
  • high-level special forms: .bit, ,count, :STR, DSTR

Practical Cautions

  • set one explicit PLC profile for every connection
  • older Flow Library 0.2.3 flows must be updated from PLC series / frame type to the current PLC profile selector
  • start with D reads before using typed, counted, or string forms
  • keep slmp-device-matrix.json for later verification, not for the first smoke test
  • do not rely on Node-RED for PLC model-specific range or upper-bound checks; format errors are local, range errors come from the PLC/runtime response
  • .bit,count is not part of the current public high-level surface
