Custom Coding Options: Overrides; Widgets, Functions, Services, Hooks & Plug Ins
TRACK: Specialists
Covers ways that script code can be utilized to create extensions and behavior overrides for VTScada
Designed for VTScada script developers, this intensive one-day workshop explores a range of custom coding techniques available within VTScada. Participants will learn how to extend platform functionality, customize system behavior, and build maintainable solutions using script modules like widgets, functions, services, and hooks. Through hands-on exercises and real-world examples, attendees will gain practical experience applying VTScada’s extensibility framework to solve complex application requirements.

Introduction to VTScada Extensibility
- Understanding the VTScada customization framework
- Selecting the right coding approach for different requirements
- Extending versus modifying existing functionality
- Best practices for maintainable custom development
Custom Widgets
- Understanding widget architecture
- Creating reusable interface components
- Adding custom graphics, controls, and interactions
- Passing parameters and managing widget properties
Writing Custom Functions
- Creating reusable scripting modules
- Function design and organization
- Input parameters and return values
- Building libraries of reusable code
- Debugging and maintaining custom functions
Developing Services
- Understanding service-based architectures in VTScada
- Creating shared background functionality
- Managing service lifecycle and state
- Real-world service implementation examples
Hooks and Event-Driven Customization
- Understanding hook-based development
- Injecting custom behavior into existing workflows
- Responding to application events
- Extending system functionality without extensive code modifications
- Common hook implementation patterns
Architecture and Design Best Practices
- Choosing the appropriate customization mechanism
- Maintaining upgrade-friendly custom code
- Reducing technical debt
