<div class="markdown_content"><p>Hi,</p> <p>It's my first time using CODESYS and I tried to create a simple program to learn how it works. I'm using CODESYS Control Win V3 to simulate the PLC. When I created the project for the first time, I was able to download the code to the PLC. However, when I closed and reopened the project and tried to download the code again, I received an error message that said "Fatal error: Overlapping code pieces have been detected". I don't know what the problem is.</p> <p>I've already tried to uninstall and reinstall CODESYS, but the same issue persists. I also attempted to download a blank code, but the same error message appeared. Additionally, I tried to restart the PLC, but it didn't solve the issue. Thank you for your help.</p></div>
