+# CSV-BlackBox-Writer
+
+This example contains two programs:
+
+- CSV_Writer_Periodically : Writes data periodically into .csv files for later retrieve in case of errors.
+  - This is useful for example if a user does not want to log into the cloud large data or several signals, but it would like to store locally ( in the device) as some kind of log book.
+  - The .csv files are stored under /var/opt/codesys/PlcLogic/CSV_BALCKBOX
+- Snapshot_Recorder: It uses a circular buffer, storing the last values of a signal "fast" in volatile memory and only write it to a file in an event
+  - It would be useful to simulate a snapshot-like recorder, with very fast data being saved in case of an accident for example.
+  - The .csv files are stored under /var/opt/codesys/PlcLogic/CSV_Snapshot
+
+Since the PlcLogic folder can be accessed from CODESYS IDE, the easier way to retrieve the files is to connect ( over remote machine tunnel) using the CODESYS gateway and IDE. Then navigate to Device --> Files and use the arrows to move files between your PC and the device.

+# CODESYS Examples
+
+A collection of **CODESYS project examples** and utilities to help you quickly prototype and learn. Each example is packaged as a `.projectarchive` and includes a README Markdown file explaining its purpose and usage.
+
+[What is a projectarchive file?](https://forge.codesys.com/forge/talk/Engineering/thread/f283955619/)
+

+
+```text
+example-folder/
+├── example.projectarchive   # The actual CODESYS project
+└── README.md                # Description and instructions
+```
+
+- **`.projectarchive`** – The CODESYS project file, ready to open.
+- **`README.md`** – Explains the example, its purpose, and any setup instructions.
+
+
+## How to Use
+
+1. Clone this repository
+2. Open the `.projectarchive` file in **CODESYS**.
+3. Read the `README.md` inside the example folder to understand the example and any setup steps.
+4. Modify or combine examples for your own projects.
+

+
+- The main branch is protected to ensure stability. Direct pushes are not allowed.
+- Contributions must be made via Pull Requests (PRs).
+- Add new examples in separate folders.
+- Each folder **must** contain:
+  - A `.projectarchive` file
+  - A `README.md` file describing the example
+- Use **clear and descriptive folder names** to make examples easy to find.
+- PRs will be reviewed before merging to ensure quality and consistency.
+
+
+## Notes
