LED Output

What is LED Output?

LED Output is a visual indicator that shows a small colored circle (like an LED) whose color changes based on a boolean value from your connected system — for example, from a PLC, runtime, or script.

It is commonly used to represent simple states like on/off, active/inactive, or true/false.

Key Features

• Displays a color indicator based on a boolean variable (true / false)
• Fully configurable colors for ON and OFF states
• Connects via Connection String
• Can be used anywhere in the UI — headers, status bars, tiles, etc.

When should you use it?

Use LED Output when:

• You want to visualize binary status (e.g. system active, valve open)
• You need a compact and clear state display
• You want to show alarm status, connectivity, or sensor triggers

Practical Example

You connect the LED to a variable valveOpen:

valveOpen = true → LED = green (ON)
valveOpen = false → LED = red (OFF)
