Visibility
Connection String
A Connection String specifies the source from which a value is retrieved. This is typically a variable, register, or system state from an external control system such as CODESYS, a PLC, or a database. The connection string is essential for enabling dynamic behavior in the interface.
Where It’s Used
Connection strings are used in:
- Visibility conditions (e.g. show/hide based on live status)
- Input fields (reading or writing values)
- Gauges, indicators, and dynamic UI elements
How to Create One
If no connection exists yet, you must define it first:
- Navigate to Menu > Connections > New (+)
- Enter the connection type, target, and relevant parameters
- Save the connection
How It Works
- Once created, the connection string appears as an option in dropdown menus (e.g. in visibility settings)
- It can then be linked to conditions that evaluate live values from the external system
- The UI reacts in real time based on these external signals
This setup ensures that your interface remains tightly coupled to live operational data.
A Connection String defines where a value is retrieved from—typically a variable, register, or state from an external system such as CODESYS, a PLC, or a database. It forms the basis for evaluating conditions in visibility logic, input fields, gauges, and more. If no connections have been set up yet, you must first define one: Go to Menu > Connections > New + to create a new connection string. Once configured, the string can be selected from a dropdown menu in the visibility panel and bound to conditions.
