Tables Overview
The Tables module in PLCVisu allows you to display and interact with structured data inside your visualization. It supports multiple table types, each with a different data source and interaction model — from live CODESYS integration to database-connected historic views.
Table Types
PLCVisu offers four main table types:
1. Online Table
- Connected directly to CODESYS (not to a database)
- Displays live, streaming data from running systems
- Does not support history or filtering by time
- Ideal for real-time system monitoring
- CODESYS integration must be configured separately
2. Basic Table
- Connected to a selected database (e.g. SQLite, MySQL, MSSQL, Trends)
- Displays historical data stored in the database
- Read-only — cannot be modified in the frontend
- Best suited for reports, logs, or data overviews
3. Editable Table
- Also connected to a selected database
- Fully editable in the frontend (add, delete, change values)
- Editing depends on assigned user permissions
- Ideal for operator input, manual records, or user-managed data
4. Advanced Table
- Same core as Editable Table, but with advanced visual logic
- Supports dynamic images based on cell values via JSON rules
- Example: Show a battery icon that changes based on charge level
