Settings are organized by module and scope, with descriptions of each parameter, valid ranges, and impacts on system behavior.

Core Modules

Data Management:

  • Tags (UNS) - Unified Namespace for real-time data management
  • Devices - Communication with field devices and PLCs
  • Historian - Time-series data storage and retrieval
  • Datasets - SQL database synchronization and queries

Process Control:

  • Alarms - Condition monitoring and notification management
  • Scripts - Data processing and workflow automation
  • Reports - Document generation (PDF/CSV) and data exchange (JSON/XML)

User Interface:

  • Displays - Operator visualization and control interfaces
  • Security - Access control and user authorization

Module Lifecycle

The module lifecycle follows these states:

  1. Initialized - Module loaded, configuration read
  2. Starting - Resources allocated, connections established
  3. Running - Active operation, processing data
  4. Stopping - Graceful shutdown initiated
  5. Stopped - Resources released, module inactive

Module Communication

All modules communicate through the central TServer process:

  • Tag Database acts as the central data hub
  • Event System manages inter-module notifications
  • Message Queue handles asynchronous operations
  • Shared Memory enables high-speed data exchange

Data Flow Patterns

Common Configuration Patterns

Pattern 1: PLC to Display

  • PLC → Device Driver → Tag Database → Display Client

Pattern 2: Direct Device Binding

  • PLC Address → Dynamic TagProvider → Display (bypasses Tag Database)

Pattern 3: Calculated Values

  • Source Tags → Script Engine → Result Tag → Dataset → SQL Database

Pattern 4: Operator Commands

  • Display Button → Tag Write → Device Driver → PLC
  • Parallel Path: Tag Write → Audit Log (when enabled)

Pattern 5: Alarm Notification

  • Tag Value Change → Alarm Condition → Notification System → Email/SMS
