Visibility

Connection Condition

The Connection visibility condition controls whether a UI element is shown or hidden based on a live value received from an external system via a connection string. This is typically linked to a PLC or runtime environment like CODESYS.

Use Cases

  • Show an element only when a machine is running
  • Hide a button if a specific BOOL variable is false
  • Display a warning panel if a numeric threshold is exceeded

How It Works

  • A variable from the control system is monitored through a Connection String

  • Logic conditions can be applied, such as:

    • is equal to / not equal to
    • greater than / less than
    • Boolean true / false

  • When the condition is satisfied, the UI element becomes visible; otherwise, it remains hidden

Benefits

  • Enables real-time interface reactions based on live data
  • Supports fully dynamic UI behavior linked to system state
  • Reduces the need for manual interface updates or refreshes

Use the Connection condition to make your interface process-aware and fully responsive to the underlying control system.
