Scripts Module Overview
The Scripts module enables server-client programming and parallel execution using .NET (C#, VB.NET) and Python 3, providing the foundation for high-performance custom logic and data processing.
Scripts Module links: How-to Guide, Reference
The Scripts Module enables the easy creation of server-client programming and parallel execution. Allowing interoperability of .NET (C#, VB) and Python 3, it it the foundation module to hight performance and flexible application.
The Script MåΩodule implements:
Tasks: code execute in reaction to events, or time-based.
Classes: Library of methods for server and client execution
Expressions: optimized event execution or tags changes, and other trigger conditions.
Key Concepts
- *ScriptTask*: Code that executes in response to events or time-based triggers
- *ScriptClass*: Library of reusable methods for server and client execution
- *ScriptExpression*: Single-line code for simple event responses
- *References*: External DLLs included for script compilation
What It Does
- Executes custom business logic and data processing
- Provides server-side and client-side code execution
- Handles event-driven and time-based automation
- Enables data normalization and enrichment
- Integrates with third-party .NET and Python libraries
- Supports multi-threaded parallel execution
Configuration Workflow
Scripts Module Configuration Workflow | ||
|---|---|---|
Step | Action | Description |
Create ScriptClasses | Build function libraries | Define reusable methods for your solution |
Create ScriptTasks | Implement business logic | Add data processing and automation code |
Create ScriptExpressions | Add simple actions | Single-line responses to events |
Add References | Include external libraries | Import DLLs for extended functionality |
Runtime Behavior
Execution Environment
The server creates dedicated processes with multi-threading to execute tasks and expressions based on configured triggers. Each process runs in isolated application domains for security and performance.
Client-Server Architecture
A service enables client displays and distributed modules to request server-side class execution, providing centralized logic accessible from any client.
Performance Monitoring
Built-in diagnostics track execution time for each task, enabling performance optimization and troubleshooting.
Features Highlights
- *Multi-Language Support* - C#, VB.NET, Python 3, and JavaScript in a single solution
- *Integrated Code Editor* - IntelliSense, debugging, breakpoints, and step-through execution
- *Server and Client Domains* - Scripts execute globally (server) or locally (client)
- *Flexible Triggers* - Date, time, condition, calendar, tag change, or interval-based execution
- *Native Object Access* - Direct IntelliSense access to tags, datasets, alarms as .NET objects
- *Python Configuration* - Configure any Python interpreter version per project
- *Isolated Execution* - Scripts run separate from real-time database for stability
- *Code Translation* - Convert between C# and VB.NET anytime
- *Third-Party Integration* - Import and use external .NET assemblies and Python packages
- *Multi-Threaded Processing* - Parallel task execution for maximum performance
