Signed-off-by: dependabot[bot] Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Add PLC communication guide (#264) * Add post process station and related resources - Created JSON configuration for post_process_station and its child post_process_deck. - Added YAML definitions for post_process_station, bottle carriers, bottles, and deck resources. - Implemented Python classes for bottle carriers, bottles, decks, and warehouses to manage resources in the post process. - Established a factory method for creating warehouses with customizable dimensions and layouts. - Defined the structure and behavior of the post_process_deck and its associated warehouses. * feat(post_process): add post_process_station and related warehouse functionality - Introduced post_process_station.json to define the post-processing station structure. - Implemented post_process_warehouse.py to create warehouse configurations with customizable layouts. - Added warehouses.py for specific warehouse configurations (4x3x1). - Updated post_process_station.yaml to reflect new module paths for OpcUaClient. - Refactored bottle carriers and bottles YAML files to point to the new module paths. - Adjusted deck.yaml to align with the new organizational structure for post_process_deck. * Add PLC communication guide for AI4M Add a comprehensive developer guide (docs/developer_guide/add_PLC.md) describing the PLC integration standard used by Uni-Lab for workstation devices, using the AI4M implementation as reference. Covers rationale for using OPC UA, the opcua_nodes_*.csv node-table format, communication base classes (BaseOpcUaClient / OpcUaClientWithSubscription), data types, and subscription/cache/reconnect behavior. Documents driver patterns for AI4MDevice, three handshake paradigms (pulse, parameter handshake, id-based), registry/graph configuration (YAML/JSON), debugging tips (KEPServerEX sim, standalone run), and a checklist for onboarding new PLC-controlled equipment. --- .conda/base/recipe.yaml | 4 +- .conda/environment/recipe.yaml | 2 +- .conda/full/recipe.yaml | 4 +- .cursor/skills/add-device/SKILL.md | 267 +++++++- .cursor/skills/virtual-workbench/SKILL.md | 20 +- .../skills/virtual-workbench/action-index.md | 21 +- .github/workflows/ci-check.yml | 2 +- .github/workflows/conda-pack-build.yml | 2 +- .github/workflows/deploy-docs.yml | 8 +- .github/workflows/multi-platform-build.yml | 2 +- .github/workflows/unilabos-conda-build.yml | 2 +- docs/developer_guide/add_PLC.md | 611 ++++++++++++++++++ recipes/msgs/recipe.yaml | 2 +- recipes/unilabos/recipe.yaml | 2 +- setup.py | 2 +- unilabos/__init__.py | 2 +- unilabos/app/ws_client.py | 12 +- unilabos/ros/nodes/base_device_node.py | 36 +- unilabos/ros/nodes/presets/host_node.py | 13 +- unilabos_msgs/package.xml | 2 +- 20 files changed, 971 insertions(+), 45 deletions(-) create mode 100644 docs/developer_guide/add_PLC.md diff --git a/.conda/base/recipe.yaml b/.conda/base/recipe.yaml index 2916af79..57318aae 100644 --- a/.conda/base/recipe.yaml +++ b/.conda/base/recipe.yaml @@ -3,7 +3,7 @@ package: name: unilabos - version: 0.11.2 + version: 0.11.3 source: path: ../../unilabos @@ -54,7 +54,7 @@ requirements: - pymodbus - matplotlib - pylibftdi - - uni-lab::unilabos-env ==0.11.2 + - uni-lab::unilabos-env ==0.11.3 about: repository: https://github.com/deepmodeling/Uni-Lab-OS diff --git a/.conda/environment/recipe.yaml b/.conda/environment/recipe.yaml index 4ee6b75c..c41dac2b 100644 --- a/.conda/environment/recipe.yaml +++ b/.conda/environment/recipe.yaml @@ -2,7 +2,7 @@ package: name: unilabos-env - version: 0.11.2 + version: 0.11.3 build: noarch: generic diff --git a/.conda/full/recipe.yaml b/.conda/full/recipe.yaml index 6db0d77a..b3a83990 100644 --- a/.conda/full/recipe.yaml +++ b/.conda/full/recipe.yaml @@ -3,7 +3,7 @@ package: name: unilabos-full - version: 0.11.2 + version: 0.11.3 build: noarch: generic @@ -11,7 +11,7 @@ build: requirements: run: # Base unilabos package (includes unilabos-env) - - uni-lab::unilabos ==0.11.2 + - uni-lab::unilabos ==0.11.3 # Documentation tools - sphinx - sphinx_rtd_theme diff --git a/.cursor/skills/add-device/SKILL.md b/.cursor/skills/add-device/SKILL.md index 522c05bf..dc77c6b7 100644 --- a/.cursor/skills/add-device/SKILL.md +++ b/.cursor/skills/add-device/SKILL.md @@ -5,9 +5,98 @@ description: Guide for adding new devices to Uni-Lab-OS (接入新设备).

表**描述,这是 PC 端和 PLC 端**唯一的接口契约**。 +位置示例:`unilabos/devices/workstation/AI4M/opcua_nodes_AI4M.csv`。 + +### 2.1 列定义 + +| 列名 | 是否必填 | 说明 | +|---|---|---| +| `Name` | ✅ | 节点名(PLC 工程师在 PLC 项目中真实使用的变量名,通常是中文/原始名) | +| `EnglishName` | 推荐 | 英文别名,**PC 端代码全部用这个名字**调用 | +| `NodeType` | ✅ | `VARIABLE`(变量)或 `METHOD`(方法),AI4M 全部用变量 | +| `DataType` | ✅ | `BOOLEAN` / `INT16` / `INT32` / `FLOAT` /

`mag_stirrer_c{0..4}_stir_speed`(搅拌仪 0~4 的搅拌速度) + - `station_{1..3}_process_complete`(检测站 1~3 的完成信号) + - `robot_rack_pick_beaker_{1..5}_complete`(取烧杯 1~5 的完成信号) + + 这样在驱动里可以直接 `f"mag_stirrer_c{idx}_stir_speed"` 拼出节点名。 + +2. **数据类型与 PLC 侧严格一致**: + - `BOOL` → `BOOLEAN`,`INT/WORD` → `INT16/UINT16`,`DINT` → `INT32`,`REAL` → `FLOAT`。 + - 类型不一致会触发 `BadTypeMismatch`,写入失败。 + +3. **NodeId 必须从 PLC 工程或 OPC UA Server 中导出**,不要自己拼。 + 常见格式: + - 西门子 1500:`ns=4;s=上位通讯变量|<变量名>` + - 倍福 TwinCAT:`ns=4;s=PLC1.MAIN.<变量名>` + - KEPServerEX:`ns=2;s=Channel1.Device1.` + +4. **每个工站一个独立 CSV**,不要共用。 + AI4M 中真机用 `opcua_nodes_AI4M.csv`,仿真用 `opcua_nodes_AI4M_sim.csv`。 + +--- + +## 3. 通信基类架构 + +文件:`unilabos/devices/workstation/AI4M/base_opcua_client.py` + +整个通信层分两层: + +``` +BaseOpcUaClient # 最小可用:连接 + 节点注册 + 读写 + 方法调用 + ▲ + │ 继承 + │ +OpcUaClientWithSubscription # 生产可用:+ 订阅推送 + 缓存 + 自动重连 + ▲ + │ 继承 + │ +AI4MDevice # 业务驱动:在它之上写设备动作函数 +``` + +### 3.1 `BaseOpcUaClient` 核心能力 + +```python +class BaseOpcUaClient(UniversalDriver): + client: Optional[Client] = None + _node_registry: Dict[str, OpcUaNodeBase] = {} # name -> Variable/Method + _name_mapping: Dict[str, str] = {} # 英文名 -> 中文名 + _reverse_mapping: Dict[str, str] = {} # 中文名 -> 英文名 + _found_node_objects: Dict[str, Any] = {} # 缓存 ua.Node 用于订阅 + + @classmethod + def load_csv(cls, file_path) -> Tuple[List[OpcUaNode], dict, dict]: ... + def register_node_list(self, node_list) -> "BaseOpcUaClient": ... + def use_node(self, name) -> OpcUaNodeBase: ... + def read_node(self, node_name: str) -> str: ... # 返回 JSON + def write_node(self, json_input: str) -> str: ... + def call_method(self, node_name, *args) -> Tuple[Any, bool]: ... +``` + +它做的事情可以归纳为四步: + +1. **`load_csv`**:读取节点表,建立 `Name ↔ EnglishName` 双向映射。 +2. **`register_node_list`**:把节点登记进 `_variables_to_find` 待查找列表。 +3. **`_connect` → `_find_nodes`**:连上 OPC UA 后,按 `NodeId` 把每个节点解析成 `Variable` / `Method` 对象,放进 `_node_registry`。 +4. **`use_node(name)`**:业务代码取节点的唯一入口,**支持中英文混用**,找不到会自动重试一次。 + +### 3.2 `OpcUaClientWithSubscription` 增强能力 + +在 `BaseOpcUaClient` 基础上提供三个生产环境必备的能力: + +#### a) 订阅缓存(高频读零开销) + +```python +def _setup_subscriptions(self): + self._subscription = self.client.create_subscription( + self._subscription_interval, # 默认 500ms + SubscriptionHandler(self), + ) + for node_name, node in self._node_registry.items(): + if node.type == NodeType.VARIABLE and node.node_id: + handle = self._subscription.subscribe_data_change(ua_node) + self._subscription_handles[node_name] = handle +``` + +当 PLC 侧变量变化时,`datachange_notification` 回调会把新值写进 `self._node_values[name]`, +后续 `get_node_value` 优先读缓存——**业务代码可以放心地写 `while not self.get_node_value(...): time.sleep(1)` 而不用担心 OPC UA 频繁请求**。 + +#### b) 智能缓存的 `get_node_value` + +```python +def get_node_value(self, name, use_cache=True, force_read=False): + # 1. 中英文名归一化 + chinese_name = self._name_mapping.get(name, name) + + # 2. force_read=True 强制透传到 OPC UA Server + if force_read: ... + + # 3. 命中订阅推送 → 直接返回缓存 + # 4. 命中按需读 + 未过期(cache_timeout=5s)→ 返回缓存 + # 5. 否则发起 read 并更新缓存 +``` + +#### c) 连接监控 + 自动重连 + +后台线程每 30s 调一次 `client.get_namespace_array()` 探活,断线则自动 `disconnect → connect → 重新订阅`,最多重试 5 次。 + +### 3.3 数据类型 / 节点类型 + +`unilabos/device_comms/opcua_client/node/uniopcua.py`: + +```python +class DataType(Enum): + BOOLEAN = VariantType.Boolean + INT16 = VariantType.Int16 + INT32 = VariantType.Int32 + FLOAT = VariantType.Float + STRING = VariantType.String + # ... + +class NodeType(Enum): + VARIABLE = NodeClass.Variable + METHOD = NodeClass.Method + OBJECT = NodeClass.Object +``` + +`Variable.write()` 内部会按 `DataType` 做强制类型转换, +所以 CSV 里的 `DataType` 列就是"PC 端转换写入值的类型说明书"。 + +--- + +## 4. 编写设备驱动:以 `AI4MDevice` 为例 + +文件:`unilabos/devices/workstation/AI4M/AI4M.py` + +### 4.1 继承通信基类,最小骨架 + +```python +from typing import Optional +from unilabos.devices.workstation.AI4M.base_opcua_client import OpcUaClientWithSubscription + +class AI4MDevice(OpcUaClientWithSubscription): + def __init__( + self, + url: str, # opc.tcp://192.168.1.10:4840 + deck: Optional[AI4M_deck] = None, # 物料台面(资源树) + csv_path: str = None, # 节点表 CSV + username: str = None, + password: str = None, + use_subscription: bool = True, + cache_timeout: float = 5.0, + subscription_interval: int = 500, + *args, **kwargs, + ): + super().__init__( + url=url, username=username, password=password, + use_subscription=use_subscription, + cache_timeout=cache_timeout, + subscription_interval=subscription_interval, + *args, **kwargs, + ) + + # 物料台面初始化(见教程 4. 物料系统) + self.deck = deck or AI4M_deck(setup=True) + self._robot_lock = threading.Lock() + + # 关键:加载节点表 + if csv_path: + self.load_nodes_from_csv(csv_path) +``` + +`load_nodes_from_csv` 会一次性完成:解析 CSV → 注册节点 → 解析 NodeId → 建立订阅, +**之后整个驱动都通过 `self.get_node_value(name)` / `self.set_node_value(name, value)` 操作 PLC**。 + +### 4.2 PLC 通信的核心模式:握手协议(Handshake) + +PLC 编程的本质是"扫描周期 + 状态机",PC 端**绝对不能用 fire-and-forget 的方式发指令**。 +和 PLC 配合的标准模式是 **"PC 写指令 → PC 等待 PLC 回执 → PC 复位指令"**。 + +AI4M 中所有 `trigger_*` 函数都遵循以下三种握手范式之一: + +#### 范式 A:脉冲触发 + 完成信号(最常用) + +```python +def trigger_init(self) -> dict: + # ① 复位上一轮残留 + self.set_node_value("alarm_reset", True); time.sleep(1.0) + self.set_node_value("alarm_reset", False) + self.set_node_value("manual_auto_switch", False) + + # ② 等待 PLC 退出自动模式 + while self.get_node_value("auto_mode"): + time.sleep(1.0) + + # ③ 发起初始化脉冲(True → False) + self.set_node_value("initialize", True); time.sleep(1.0) + self.set_node_value("initialize", False) + + # ④ 等待 PLC 给出完成信号 + while not self.get_node_value("init finished"): + time.sleep(1.0) + + return {"message": "设备初始化完成"} +``` + +要点: +- **"PC 写一个 BOOL 拉高再拉低"** 模拟脉冲,PLC 用上升沿触发动作。 +- **`get_node_value` 要在 while 循环里轮询**,配合订阅缓存基本无压力。 +- **每个动作必须有"开始"和"完成"两个独立的 BOOL 节点**,不能复用。 + +#### 范式 B:参数下发 + 请求/已执行/完成 三步握手(带数据的工艺) + +```python +def trigger_station_process(self, station_id: int, mag_stir_speed: int, ...): + request_node = f"station_{station_id}_request_params" + params_received_node = f"station_{station_id}_params_received" + start_node = f"station_{station_id}_start" + complete_node = f"station_{station_id}_process_complete" + + # ① PC 复位三个状态位(避免上一轮影响) + self._reset_station_process_flags(station_id) + + # ② 等 PLC 主动请求参数(PLC 准备好了才接收) + while not self.get_node_value(request_node): + time.sleep(1.0) + + # ③ PC 下发参数(注意:PLC 内部数组是 0-based,PC 暴露给用户是 1-based) + station_idx = station_id - 1 + self.set_node_value(f"mag_stirrer_c{station_idx}_stir_speed", mag_stir_speed) + self.set_node_value(f"mag_stirrer_c{station_idx}_heat_temp", mag_stir_heat_temp) + self.set_node_value(f"mag_stirrer_c{station_idx}_time_set", mag_stir_time_set) + self.set_node_value(f"syringe_pump_{station_idx}_abs_position_set", syringe_pump_abs_pos) + + # ④ PC 通知 PLC "参数已就绪",等 PLC 回复"已执行" + self.set_node_value(start_node, True) + while not self.get_node_value(params_received_node): + time.sleep(1.0) + + # ⑤ 等 PLC 完成整个工艺 + while not self.get_node_value(complete_node): + time.sleep(5.0) + + self.set_node_value(start_node, False) # 复位,方便下一轮 + return {"station_id": station_id, "message": "..."} +``` + +四个状态位的语义: + +| 信号 | 方向 | 含义 | +|---|---|---| +| `station_X_request_params` | **PLC → PC** | "我准备好了,把参数给我" | +| `station_X_start` | **PC → PLC** | "参数我已经写好了,开干" | +| `station_X_params_received` | **PLC → PC** | "参数我已经吃下了" | +| `station_X_process_complete` | **PLC → PC** | "工艺已经做完" | + +**这是 PLC 通信教科书级别的标准范式**,所有带数据下发的动作都建议照抄。 + +#### 范式 C:编号下发 + 编号对应的完成信号(多目标互锁) + +```python +def trigger_robot_pick_beaker(self, pick_beaker_id: int, place_station_id: int = None, ...): + # ① 等机器人空闲(互锁) + while not self.get_node_value("robot_ready"): + time.sleep(1.0) + + # ② 阶段一:下发"取哪一杯"编号 + 等"取这一杯完成" + pick_complete_node = f"robot_rack_pick_beaker_{pick_beaker_id}_complete" + self.set_node_value("robot_pick_beaker_id", pick_beaker_id) + while not self.get_node_value(pick_complete_node): + time.sleep(1.0) + + # ③ 阶段二:下发"放到哪个工站"编号 + 等"放完成" + place_complete_node = f"robot_place_station_{place_station_id}_complete" + self._reset_station_process_flags(place_station_id) + self.set_node_value("robot_place_station_id", place_station_id) + while not self.get_node_value(place_complete_node): + time.sleep(1.0) +``` + +要点: +- **同一个动作的多个目标用"编号变量 + 编号对应的完成信号"实现**,不要每个目标都开一个开始位。 +- **配合 Python 端 `threading.Lock()` 做软互锁**,避免多个线程争抢机器人。 +- **每个阶段有独立的完成信号**,串行等待,不能合并。 + +### 4.3 一些容易踩坑的细节 + +1. **节点名映射** + `set_node_value("alarm_reset", True)` 实际写入的是 CSV 中文名 `报警复位`, + `get_node_value` 同理。**业务代码全部用 EnglishName**,不要直接用中文。 + +2. **PLC 数组索引和 PC 不一致** + AI4M 里 PC 暴露 `station_id ∈ {1, 2, 3}`,但 PLC 内部数组是 `C[0..2]`, + 驱动里要做 `station_idx = station_id - 1`,**这种映射只在驱动层做一次**, + 不要让上层(registry / 实验记录本)感知。 + +3. **订阅模式下 BOOL 节点的边沿同步** + 订阅有 ~500ms 延迟。如果你刚 `set_node_value(x, True)` 就立刻 `get_node_value(x)`, + 读到的可能还是 `False`(订阅还没推回来)。 + 解决方案:**写完后用 `force_read=True` 透传一次** 或加一段 `time.sleep`。 + +4. **永远不要忘记复位** + `start` 拉 True 后必须有地方拉回 False,否则下一轮 PLC 上升沿不触发。 + AI4M 在 `_reset_station_process_flags` 中统一做: + + ```python + def _reset_station_process_flags(self, station_id: int) -> None: + self.set_node_value(f"station_{station_id}_process_complete", False) + self.set_node_value(f"station_{station_id}_start", False) + self.set_node_value(f"station_{station_id}_params_received", False) + ``` + +5. **耗时长的等待 sleep 加大** + 工艺等待用 `time.sleep(5.0)`,机器人等待用 `time.sleep(1.0)`,初始化等待 `time.sleep(1.0)`, + 不要全部用 0.1s 轮询,会把日志刷爆。 + +--- + +## 5. 把驱动接到 Uni-Lab:Registry + Graph + +### 5.1 Registry YAML(动作 schema) + +文件:`unilabos/registry/devices/AI4M_station.yaml` + +```yaml +AI4M_station: + category: [AI4M_station] + class: +

指向驱动类(`module:ClassName`)。 +- `action_value_mappings` 中的 key 形如 `auto-<方法名>`,对应驱动里的同名 Python 方法。 +- `schema.goal` 自动转成 ROS2 Action 的 goal 消息,`schema.result` 转 result。 +- `init_param_schema.config` 对应 `__init__` 的入参,**所有需要现场改的参数都要列出来**(最重要的就是 `url` 和 `csv_path`)。 +- `always_free: true` 表示该动作不占用工站独占锁(多检测站可并发执行)。 + +### 5.2 Graph JSON(实例化) + +文件:`unilabos/devices/workstation/AI4M/AI4M.json` + +```json +{ + "nodes": [ + { + "id": "AI4M_station", + "name": "AI4M_station", + "type": "device", + "class": "AI4M_station", + "children": ["AI4M_deck"], + "parent": null, + "config": { + "url":

+ } + ] +} +``` + +要点: +- `class` 必须和 Registry YAML 的顶层 key 完全一致(`AI4M_station`)。 +- `config` 字段**逐字传给驱动 `__init__`**,所以 Graph JSON = "现场参数表"。 +- 多套相同设备时拷贝一份,把 `id` / `url` 改掉即可(参考 `AI4M002_station`)。 + +### 5.3 启动命令(来自 `start.md`) + +```cmd +# 真机 +python unilabos/app/main.py -g unilabos/devices/workstation/AI4M/AI4M.json ` + --ak --sk --upload_registry --addr --disable_browser + +# 仿真(KEPServerEX

+### 6.3 看日志判断卡在哪 + +`base_opcua_client.py` 的日志已经覆盖了所有关键节点: + +``` +✓ 客户端已连接! +✓ 找到变量节点: 'robot_ready', NodeId: ns=4;s=... +✓ 已订阅节点: robot_ready +✓ 节点查找完成:所有 142 个节点均已找到 +``` + +如果看到 `⚠ 以下 N 个节点未找到`,**99% 是 CSV 里的 NodeId 写错了**,回去对一下 PLC 工程导出的 NodeId。 + +### 6.4 检查节点是否能直接读写 + +```python +# 透传读,绕过订阅缓存 +A4.get_node_value("robot_ready", force_read=True) + +# 直接读 JSON 形式(适合从 HTTP/调试面板调) +A4.read_node("robot_ready") + +# 写 +A4.set_node_value("alarm_reset", True) +A4.write_node('{"node_name": "alarm_reset", "value": false}') +``` + +--- + +## 7. 接入新 PLC 设备的 Checklist + +接到一台新工站时,按下面顺序做就能保证不漏: + +- [ ] 1. 让 PLC 工程师把上位通讯变量整理到 OPC UA Server,导出 NodeId 清单。 +- [ ] 2. 在 `unilabos/devices/workstation/<设备名>/` 下新建目录,复制 `AI4M/base_opcua_client.py` 不动。 +- [ ] 3. 整理
