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.

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

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.  It 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. 

  • 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

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
