OFF Delay

This function block holds a boolean signal high for a configurable time when the input changes from True to False. Use it to prevent brief false pulses from immediately turning an output off.

📥 Inputs

Input Signal A boolean signal that controls the block. Provide True/False values (or connect a boolean-producing function block).

📤 Outputs

Output Signal The resulting boolean after the off-delay logic. When the input falls from True to False, this output remains True until the configured delay elapses.

🕹️ Controls

Delay Time (seconds) Set how long the output stays True after the input goes False. Enter the delay duration in seconds (supports decimal values).

⚙️ Running mechanism

• The block monitors the incoming boolean signal and remembers its recent state.

• When the input transitions from True to False, an internal timer starts and the block keeps the Output Signal as True.

• If the configured delay time passes without the input returning to True, the block then sets the Output Signal to False.

• If the input returns to True before the delay finishes, the delay is canceled and the output follows the input immediately.

• On initial start the block waits for the first input change to begin normal operation.

🎯 Features

• Prevents short-lived false pulses from toggling downstream logic.

• Simple numeric control for delay length in seconds.

• Works with any boolean-producing blocks or signals in your scenario.

• Stateless on removal — releases internal timers when removed from the flow.

📝 Usage instructions

1. Connect a boolean source (for example a manual switch or a logic-producing block) to the Input Signal.

2. Set Delay Time (seconds) to the duration you want the output to remain True after a falling edge.

3. Use the Output Signal to drive downstream logic or indicators.

💡 Tips and Tricks

• For manual testing, use the Logic Input block as a controllable boolean source.

• To add a delay on the rising edge as well, pair this block with the ON Delay block for symmetric behaviour.

• Detect single transitions then delay the fall by combining with the Rising Edge block upstream.

• Use logical combinations like And, Or, or Set - Reset with this block to create more advanced control flows (for example, require multiple conditions to be True before the delay behavior is allowed).

• Connect the output to Led Output or Scope to visualize or indicate the delayed state in the UI.

🛠️ Troubleshooting

• If the output never goes False: check the value entered in Delay Time (seconds) and confirm the input actually transitions to False.

• If the output drops immediately: verify the input truly went from True to False and that no upstream blocks (like a pulse generator) are briefly forcing the input low.

• If you need to ignore spurious signals, consider adding a short ON Delay before this block or pre-filtering with logical conditions.
