# 🤖 OPC UA Robot Control Dashboard
# opcuaCOM_PY
**Version 2.0** - Modernes Streamlit-Dashboard für OPC UA Robotersteuerung
Simuliertes Drücken von definierten Tasten (START, STOP...) über OPCUA
## 📋 Übersicht
Dieses Projekt ermöglicht die Steuerung eines Roboters über OPC UA (OPC Unified Architecture) durch ein benutzerfreundliches Web-Dashboard. Das Dashboard ersetzt die ursprünglichen Batch-Dateien durch eine moderne, interaktive Oberfläche.
## ✨ Features
### 🎮 **Control Buttons**
- **🔧 INIT** - Adaptiert Zugriffsrechte für OPC UA
- **▶️ START** - Startet den Roboterprozess
- **⏹️ STOP** - Stoppt den Roboterprozess
- **🔄 RESET** - Setzt das System zurück
### 🖥️ **Dashboard Features**
- **Moderne Web-Oberfläche** mit Streamlit
- **Echtzeit-Status** der OPC UA Verbindung
- **Activity Log** mit Zeitstempel
- **Responsive Design** für verschiedene Bildschirmgrößen
- **Schöne Icons** und Hover-Effekte
## 🚀 Installation & Start
### Voraussetzungen
- **Anaconda** oder **Miniconda** installiert
- **Python 3.10+**
### Automatische Installation
1. **Repository klonen:**
```bash
git clone <repository-url>
cd opcuaCOM_PY
```
2. **Dashboard starten:**
- **Windows:** Doppelklick auf `EXEC_DASHBOARD.bat`
- **Manuell:**
```bash
conda env create -f environment.yml
conda activate opcua_com
streamlit run app.py --server.port 8505
```
### Manuelle Installation
```bash
# Conda-Umgebung erstellen
conda env create -f environment.yml
# Umgebung aktivieren
conda activate opcua_com
# Dashboard starten
streamlit run app.py --server.port 8505
```
## ⚙️ Konfiguration
### OPC UA Server
Bearbeiten Sie `cfg.yaml` für Ihre OPC UA Server-Einstellungen:
```yaml
cred:
robot:
url: "opc.tcp://192.168.214.1:4840"
username: "OpcUaClient"
password: "OPCUACLIENT"
```
### Button-Mapping
Die Button-Zuordnungen sind in `cfg_varlist.csv` definiert:
```csv
BTN_START ns=2;s=LBP_Chan1.A_NCStart
BTN_STOP ns=2;s=LBP_Chan1.A_NCStop
BTN_RESET ns=2;s=LBP_Chan1.A_Reset
```
## 🎯 Verwendung
1. **Dashboard öffnen:** `http://localhost:8505`
2. **Verbindung initialisieren:** "🔌 Initialize Connection" klicken
3. **Status prüfen:** Sollte "Connected" anzeigen
4. **Buttons verwenden:** INIT, START, STOP, RESET

- **Backend:** OPC UA Client mit Threading
- **Datenbank:** InfluxDB für Logging
- **Konfiguration:** YAML-basiert
## 🆚 Version History
### v2.0 (Aktuell)
- ✅ Streamlit Dashboard hinzugefügt
- ✅ Moderne Web-Oberfläche
- ✅ Automatische Conda-Umgebungsverwaltung
- ✅ Verbesserte Fehlerbehandlung
### v1.0 (Legacy)
- Batch-Dateien für Button-Steuerung
- Kommandozeilen-basierte Ausführung
## 📞 Support
Bei Problemen oder Fragen:
1. Prüfen Sie die Activity Logs im Dashboard
2. Überprüfen Sie die OPC UA Server-Verbindung
3. Stellen Sie sicher, dass alle Abhängigkeiten installiert sind
