Tables

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
