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 :(
Hi. I tested your recommendation (to use GPIO B+/Pi2) but still all the GPIO pins are initially in TRUE value after running the program. See attached picture. Thanks :))

Hi,
if you use PI4 it is mandatory to use:
GPIO B+/PI2 in the configuration.
Please post your questions just once here not in several threads.
