Troubleshooting and Optimization

Common Issues and Solutions

  1. Slow performance: Optimize project settings and clean up unused data.

  2. Inconsistent connections: Use the "Check Project" function to identify and fix issues.

  3. Missing components: Ensure all required libraries are loaded and up to date.

Optimizing Workflow

  1. Create custom keyboard shortcuts for frequently used functions.

  2. Develop and use standardized macros for common circuit elements.

  3. Utilize the Navigator windows for quick navigation through large projects.

Placement Attributes

1. DT (Device Tag)

  • Definition: A unique identifier for a component within the project.

  • Purpose: Used to identify and reference a device consistently throughout the schematic.

  • Format: Typically follows a hierarchical structure, often derived from the project's functional and installation structure (e.g., "+C1-M1").

  • How to Use:

    • Assign to all components to ensure proper referencing.

    • Use the Device Navigator to manage and edit DTs efficiently.

2. Display DT

  • Definition: The portion of the DT visible on the schematic.

  • Purpose: Allows the user to choose which part of the DT is displayed on the diagram to avoid clutter.

  • How to Use:

    • Configure through the device’s properties.

    • Useful in complex projects where the full DT might be too verbose.

3. Full DT

  • Definition: The complete and detailed device tag, including all hierarchy and identification levels.

  • Purpose: Ensures there is no ambiguity about the component's location or function within the project.

  • How to Use:

    • Typically used in reports and documentation.

    • Critical for ensuring traceability and for large projects with strict organization.

4. Main Function

  • Definition: The primary function of a multi-function device.

  • Purpose: Identifies the core purpose of a component (e.g., a relay coil vs. its auxiliary contacts).

  • How to Use:

    • Assign a Main Function to represent the device in the schematic.

    • Sub-functions (e.g., contact points) are then linked to the main function for clarity and documentation.

5. Function Text

  • Definition: A textual description of the component’s function or role.

  • Purpose: Provides contextual information to clarify the purpose of a device or connection.

  • How to Use:

    • Enter via the device’s properties or during placement.

    • Appears alongside the component in schematics for readability.

Examples of Use in Solar Car Projects

  1. DT and Full DT: Assign unique DTs to components like relays, inverters, or sensors to track them in the wiring diagram. For example:

    • Solar Panel: +SP1

    • Battery Protection System: +BPS1

  2. Display DT: Simplify the schematic by showing only essential parts of the tag, e.g., +SP1 instead of +Car1+System1+SP1.

  3. Main Function and Sub-Functions: Use for components like relays:

    • Main Function: K1 (Relay Coil)

    • Sub-Functions: K1.1, K1.2 (Auxiliary Contacts)

  4. Function Text: Add labels like "Solar Panel Input" or "BMS Controller Output" for better documentation.

Additional Tools to Manage These Properties

  • Navigators (e.g., Device, PLC, or Cable):

    • Use these to assign, modify, and manage DTs and properties in bulk.

  • Layer Management:

    • Organize display layers to show or hide elements like Display DT or Function Text as needed.
