## Narrative

**Business context:** 设备 / PLC 信号采集 — latest-snapshot variant of the `Sp_plc_implementation*` family (proc COMMENT: "机器运行情况(全部机器最新一条)"). Returns the most recent decoded PLC reading per machine (one row each) rather than paging through history — used for a live monitoring grid where every device shows its current state.

**What it does:** Builds `Sp_plc_implementation` and `p_elemachine` temp tables the same way as the history variants; for every `elemachine WHERE iPlcNo > 0` (or the single `sMachineId` if supplied), cursors machines and pulls `LIMIT 1` from `sysdoplclog ORDER BY iIncrement DESC`, decodes the pipe slot via `Fn_split_string(sValues,'|',MOD(iPlcNo,14))`, splits by `,` into 23 metric columns including 警报灯 colour decode, 调机/生产 phase, 电表读数 (with `if(...=0,'断电',...)`), and per-stage 计数 fields.

**Invocation:** Status: appears orphaned. No `gdsmodule.sProcName` binding, no form-master sSqlStr reference, no `gdsconfigcharmaster.sProcedureName` chart binding, no other-routine caller, no xly-src reference. Signature matches the paged-report calling convention but no caller wires it — candidate for maintainer audit. See `Sp_plc_implementation2_new` for the 2024-12-07 rewrite.
