Or

This function block performs a logical OR operation on boolean signals. Use it when you need the output to be TRUE if any of the input signals are TRUE.

📥 Inputs (sockets)

• Boolean Accepts a boolean signal (default: two boolean sockets).

• Boolean Accepts a boolean signal (default: two boolean sockets).

📤 Outputs (sockets)

• Boolean The result of the OR operation (TRUE if any input is TRUE).

🕹️ Controls

This block has no interactive controls.

🎨 Features

• Simple logical OR operation for combining boolean signals.

• Default setup provides two boolean input sockets to keep UI clear and simple.

• Use in control flows, alarm logic, or decision-making branches where multiple conditions may enable the same outcome.

📝 Usage Instructions

1. Connect boolean-producing blocks (for example a manual switch or comparison block) to the input sockets.

2. Read the combined result from the Boolean output. The output will be TRUE if at least one input is TRUE.

3. Use the output to drive actuators, indicators, or further logic blocks.

📊 Evaluation

When evaluated, the block checks the boolean values on its input sockets and returns a single boolean result that represents the logical OR of all provided inputs.

💡 Tips and Tricks

• Combine with comparison blocks such as Greater, Smaller, or Equals to convert numeric checks into boolean signals before merging them with Or.

• Use Logic Input for manual on/off controls and feed multiple manual signals into Or to create a single enable signal.

• Use And and Not together with Or to build more complex boolean expressions (for example: (A AND B) OR (NOT C)).

• To react to signal changes rather than levels, pair Or with edge/temporal helpers like Edge Rising or Delay Step.

• To latch or hold results based on conditions, combine Or with Set - Reset.

• Use Debug Input to log or inspect incoming boolean signals during troubleshooting.

• Drive indicators or outputs using the result from Or with blocks like Led Output or Output to visualize or export the logical result.

🛠️ Troubleshooting

• Unexpected FALSE result: Verify all input sockets are receiving boolean signals. Use Debug Input to inspect each upstream signal.

• Floating or missing inputs: Ensure connected blocks provide valid boolean values; unconnected inputs may be treated as FALSE depending on your setup.

• Timing issues: If inputs change quickly and the result appears unstable, add Delay Step or use edge detection blocks like Edge Rising to stabilize logic transitions.
