Debug Input

This function block writes the content of its input into the log window so you can inspect runtime values. It is useful for quick checks during scenario design and troubleshooting.

📥 Inputs

Input Generic data to inspect. If the input is an image, the log will show summary info (min, max, std, size). For other data types the log shows a readable representation.

📤 Outputs

This function block does not produce any outputs.

🕹️ Controls

Controls None — this block has no interactive widgets.

🎯 Features

• Simple runtime inspection of any connected data.

• Automatic image summarization when receiving image arrays (shows min, max, standard deviation and dimensions).

• Lightweight: intended for quick checks and debugging during workflow building.

📝 Usage Instructions

1. Connect the data you want to inspect to the Input socket.

2. Run your scenario. The content of the input will be printed into the log window each time the block is evaluated.

3. Use the log output to verify expected values, data shapes, or to spot unexpected None/empty values.

📊 Evaluation

When evaluated, this function block reads the current input and posts a descriptive message to the log. Images are summarized; other data types are converted to a readable string before logging.

💡 Tips and Tricks

• Use Is None before this block to avoid logging repeated None values and to filter only meaningful data.

• Pair with Rising Edge or Logic Input to log only on specific events (for example, when a condition becomes true) so the log remains readable.

• When inspecting image streams, combine with Show Image to visually confirm what the image summary refers to.

• To store inspected values for later analysis, route data to Data Write Local or Data Write Global and view them with Data Read Local / Data Read Global.

• If you want to log numeric arrays or tabular data, consider also connecting outputs to CSV Export for persistent logging.

• Helpful combinations for common checks:

  • Visual object checks: connect outputs from Object Detection, Find Object, or Mask Detection into this block to inspect detection lists and counts.

  • OCR and text checks: feed outputs from OCR or OCR (EasyOCR) here to verify recognized text before exporting.

  • Image preprocessing debug: place this block after Blur, Image Threshold, or HSV Filter to inspect intermediate results.

🛠️ Troubleshooting

• No log output: ensure the block is connected and the scenario is running. If the input is not evaluated, try adding an upstream trigger (for example Logic Input or Rising Edge).

• Log shows large unreadable structures: for large images or long lists, use Show Image or save data with Image Logger / CSV Export instead of relying solely on the log.

• Repeated identical messages flooding the log: use event gating blocks such as Rising Edge, All True, or gating logic (And / Or) to reduce how often this block is evaluated.
