情境：主機命令執行

1. 概述

本情境描述主機遠端命令執行的完整流程，從發送命令到完成通知。

2. 前置條件

條件 必要狀態
通訊 COMMUNICATING
控制狀態 ONLINE REMOTE
製程狀態 依命令而異

3. 命令流程概述

4.2 S2F41 訊息結構

S2F41 W
<L[2]
  <RCMD "START">
  <L[2]
    <L[2]
      <CPNAME "RecipeID">
      <CPVAL "RECIPE001">
    >
    <L[2]
      <CPNAME "LotID">
      <CPVAL "LOT001">
    >
  >
>

4.3 S2F42 成功回應

S2F42
<L[2]
  <HCACK 0>           // 命令已接受
  <L[0]>              // 無參數錯誤
>

5. 命令拒絕情境

5.1 錯誤的控制狀態

sequenceDiagram participant Host participant Equipment Note over Equipment: 狀態：ONLINE LOCAL（非 REMOTE） Host->>Equipment: S2F41 W (RCMD="START") Equipment-->>Host: S2F42 (HCACK=2) Note left of Equipment: 目前無法執行<br/>（控制狀態錯誤）

回應： 

S2F42
<L[2]
  <HCACK 2>           // 目前無法執行
  <L[0]>
>

5.2 錯誤的製程狀態

sequenceDiagram participant Host participant Equipment Note over Equipment: 狀態：EXECUTING（無法 START） Host->>Equipment: S2F41 W (RCMD="START") Equipment-->>Host: S2F42 (HCACK=2) Note left of Equipment: 目前無法執行<br/>（製程狀態錯誤）

5.3 無效命令

sequenceDiagram participant Host participant Equipment Host->>Equipment: S2F41 W (RCMD="INVALID_CMD") Equipment-->>Host: S2F42 (HCACK=1) Note left of Equipment: 無效命令

5.4 參數錯誤

sequenceDiagram participant Host participant Equipment Host->>Equipment: S2F41 W Note right of Host: RCMD="START"<br/>RecipeID="NONEXISTENT" Equipment-->>Host: S2F42 Note left of Equipment: HCACK=3（參數錯誤）<br/>CPACK=2（非法值）

回應： 

S2F42
<L[2]
  <HCACK 3>           // 參數錯誤
  <L[1]
    <L[2]
      <CPNAME "RecipeID">
      <CPACK 2>       // 非法值
    >
  >
>

6. PAUSE 和 RESUME 命令

6.1 暫停序列

sequenceDiagram participant Host participant Equipment Note over Equipment: 狀態：EXECUTING Host->>Equipment: S2F41 W (RCMD="PAUSE") Equipment-->>Host: S2F42 (HCACK=0) Note over Equipment: 完成當前步驟 Note over Equipment: 狀態：PAUSING Note over Equipment: 狀態：PAUSED Equipment->>Host: S6F11 W (ProcessPaused) Note right of Equipment: 報告：PauseReason, CurrentStep Host-->>Equipment: S6F12

6.2 繼續序列

sequenceDiagram participant Host participant Equipment Note over Equipment: 狀態：PAUSED Host->>Equipment: S2F41 W (RCMD="RESUME") Equipment-->>Host: S2F42 (HCACK=0) Note over Equipment: 狀態：EXECUTING Equipment->>Host: S6F11 W (ProcessResumed) Host-->>Equipment: S6F12

7. ABORT 命令

7.1 中止序列

sequenceDiagram participant Host participant Equipment Note over Equipment: 狀態：EXECUTING Host->>Equipment: S2F41 W (RCMD="ABORT") Equipment-->>Host: S2F42 (HCACK=0) Note over Equipment: 狀態：ABORTING Note over Equipment: 安全關機序列 Note over Equipment: 狀態：IDLE Equipment->>Host: S6F11 W (ProcessAborted) Note right of Equipment: 報告：AbortReason, AbortTime Host-->>Equipment: S6F12

8. 命令逾時處理

8.1 無回應（T3 逾時）

sequenceDiagram participant Host participant Equipment Host->>Equipment: S2F41 W (RCMD="START") Note over Equipment: 設備忙碌/當機 Note over Host: T3 逾時（45 秒） Note over Host: 發出逾時錯誤

8.2 命令執行逾時

主機應在預期時間內監控完成事件：

命令 預期完成 逾時動作
START ProcessStarted 事件 查詢製程狀態
PAUSE ProcessPaused 事件 重試或升級
ABORT ProcessAborted 事件 檢查設備狀態

9. HCACK 回應碼總結

HCACK 意義 典型原因
0 已接受 命令將執行
1 無效命令 RCMD 無法識別
2 目前無法執行 狀態錯誤
3 參數錯誤 無效的 CPNAME 或 CPVAL
4 非同步完成 命令已排入佇列
5 拒絕，已在該狀態 例如：已暫停時執行 PAUSE
6 無此物件 物件參考無效
