Iaiops fab

Skill industrial-aiops/industrial-aiops/skills/iaiops-fab

Fab edition of iaiops — semiconductor / display (panel TFT-LCD/OLED) fab equipment over SECS/GEM (SEMI E5 SECS-II, E30 GEM, E37 HSMS) plus OPC-UA for the equipment's internal control layer, with the cross-protocol brain (downtime root-cause copilot, OEE, asset inventory, data quality). Use when the task mentions SECS/GEM, SECS-II, HSMS, GEM host, wafer, panel, fab equipment, MES equipment interface, SVID, ECID, ALID, PPID / process program, recipe list, or a semiconductor / display fab tool. Read-first, MOC-gated writes.From its SKILL.md

iaiops-fab — 半导体/显示 fab edition(SECS/GEM + OPC-UA + 脑)

启动:IAIOPS_MCP=fab / iaiops-mcp-fab(暴露 secsgem + opcua + s7 + modbus + 脑)。 安装:pip install iaiops[fab]。我们是 HOST(HSMS ACTIVE),设备是 equipment。

Fab 分层认知:一台 fab 设备是两层 —— MES-facing 的 SECS/GEM(HSMS) 接口,与 设备内部控制(PLC,走 OPC-UA/S7/Modbus)。职责不同,别混。S7/Modbus 工具清单见 iaiops-factory skill(fab profile 已同时暴露)。

工具

SECS/GEM(只读;设备 ↔ MES 标准,fab 入场券)

  • secsgem_equipment_status — 建立 GEM 链路 + Are-You-There(S1F1/F2)
  • secsgem_list_status_variables — SVID namelist(S1F11/F12)
  • secsgem_read_status_variables — SVID 值(S1F3/F4)
  • secsgem_list_equipment_constants — ECID namelist(S2F29/F30)
  • secsgem_read_equipment_constants — ECID 值(S2F13/F14)
  • secsgem_list_alarms — 告警表(S5F5/F6):ALID、ALCD、text
  • secsgem_list_process_programs — PPID 目录(S7F19/F20)

OPC-UA(只读;设备内控层 / opc.tcp 端点)

  • opcua_server_info / opcua_browse / opcua_read_node / opcua_read_many
  • opcua_subscribe_sample — 有界采样后返回(绝不死循环)
  • opcua_read_alarms — best-effort 活动告警/condition(untimed);opcua_alarm_events — A&C 事件订阅(带服务器时间戳)
  • opcua_read_history — HDA 历史读取([start,end] 窗口)
  • opcua_diagnose_connection — 连不上时归因(证书/安全策略/认证/防火墙/DNS/端口/配置)
  • opcua_discover_tags — 自动发现 tag 并建语义资产模型
  • opcua_health_summary — tag vs 阈值分类;opcua_anomaly_scan — 有界统计异常扫描

Fab / 质量专属(edition 工具;仅随 fab edition 加载,不进全局脑)

  • spc_check — 统计过程控制:对一段量测序列套用 Western Electric / Nelson 控制图规则 (越 3σ、2/3 越 2σ、4/5 越 1σ、连续 8 点单侧、6 点趋势),逐条按点索引报违规;给 USL/LSL 则附 Cp/Cpk。判 in_control / out_of_control。纯分析,每违规引用触发点索引。
  • defect_pareto缺陷帕累托:按缺陷类别计数排序,算各类占比与累计占比,标出到 80% 线的 关键少数(遏制/改善最有杠杆的类别)。纯分析,喂检验/缺陷记录,每占比引用计数。

跨协议脑(永远随 server 暴露)

  • 诊断:diagnose_dataflow downtime_root_cause downtime_root_cause_live downtime_triage learn_cause_weights rca_corpus_from_maintenance historian_health alarm_bad_actors tag_health subscription_health heartbeat_health alarm_flood_analysis alarm_cascade alarm_rationalization_worksheet
  • 数据质量:data_quality_scorecard data_quality_fleet_rollup
  • 分析:oee_compute downtime_events oee_multidim monitor_changes health_summary (deprecated) anomaly_scan (deprecated)
  • 资产:asset_inventory cross_protocol_asset_model adopt_alias_map diff_alias_map
  • 基线:baseline_learn baseline_check baseline_record_change baseline_status (change-log 基线:拒学薄历史、只报持续越带、每次告警必引基线样本 —— 非黑盒异常检测)
  • 合规/信创:compliance_mapping compliance_frameworks compliance_dengbao_levels compliance_report compliance_evidence_bundle historian_push export_data historian_query historian_coverage stream_publish stream_publish_event rca_narrate fleet_status fleet_incidents pdm_forecast historian_push export_data
  • 程序解读:plc_program_outline plc_program_xref plc_program_section plc_program_visibility(解读导出的 ST/AWL/L5X 程序,只读文件,强制引用行号)
  • 元:protocols_supported

Workflows

  1. Doctor-firstprotocols_supported 看配置 → iaiops doctor 探活 → secsgem_equipment_status 确认 GEM 链路(S1F1/F2 通了再谈其他)。
  2. Read-first:SVID/ECID namelist → 值 → secsgem_list_alarms;PLC 层用 OPC-UA 工具;停机问题直接 downtime_root_cause_live(advisory,引用真实信号)。
  3. MOC 写:本 edition 的 SECS/GEM 与 OPC-UA 工具均只读;fab profile 暴露的写工具 (如 s7_write_db)走统一 MOC:risk=HIGH + 默认 dry_run=True + 改前值 undo + 具名审批人 iaiops approve 双确认。未经授权绝不写生产设备。
