<div class="markdown_content"><p>Hi, i have a problem. All my GPIO pins of my raspberry pi 4 model B are always TRUE when the ladder program i created is running. See picture attached. I created a simple normally open contact in series with a coil but it turns out that my normaly open contact is having TRUE value all the time when i run the program.. Please i need help :(</p></div>
