Release v0.6.2

Date: 2026-03-13
Previous release: v0.6.1

Summary

Parameter-level error codes: wire.ParamErrorFromParam and wire.ParamErrorCodeString for 16-bit S7 parameter error codes; wire.NewS7ErrorWithParam uses the param section when present so responses report clearer messages (e.g. "block not found", "invalid request length"). Client and handshake use it when header error and param are available.
Response transport sizes: Extended to DATE, TOD, TIME, S5TIME, DT (9–12, 15), COUNTER/TIMER (28, 29), and IEC counter/timer (30, 31), HS counter (32). NormalizeResponseDataLength handles all; ResponseTransportSize constants and String() for diagnostics.
Memory areas: AreaDataRecord (0x01), AreaS7200AO (0x07), AreaIECCounter200 (30), AreaIECTimer200 (31); ValidateArea accepts them.
Diagnostic string helpers: wire.FunctionCodeString(code) (e.g. "Read Var", "Upload"), wire.AreaString(area) (e.g. "I", "DB", "M"), wire.SyntaxIDString(syntax) (e.g. "S7ANY", "DBREAD"), wire.ErrClassString(class) (e.g. "Access error"); ResponseTransportSize.String() for item-level logging.
SZL ID catalog: wire.SZLIDString(id) and expanded szlIDNames for diagnostics and logging.
Param error and SZL maps: More 16-bit parameter error codes (D003–D00B, D016–D017, D043–D04A, D061–D063, D081–D082, D0A1–D0AE, D0C1–D0C2, D250–D252, D2A1–D2A4, D401–D402, D601–D602) and additional SZL IDs in the name maps.
