<div class="markdown_content"><p>Hi,<br/> You're welcome ingo, it seems to me that's the purpose of this forum, some helped me when I was stuck, so if I can save others from spending hours looking for solutions.<br/> it would be nice if codesys looked at the problem too....<br/> otherwise, I use a raspberry pi4, and the device is updated on "GPIOs B + / Pi2" as in the picture.</p></div>

<div class="markdown_content"><p>which Raspberry Pi Model do you use? For anything newer than the Pi B, meaning Pi2, pi3, pi4 or PiB+, you should be using the other device description. (Right click the gpio, update device, select the device description "GPIOs B+/Pi2")</p></div>

<div class="markdown_content"><p>Hello everyone,<br/> if it helps:<br/> not using GPIOs_A_B, I disabled it in the program and that solved my problem.<br/> although GPIOs appear as "not used", it seems that this is not taken into account well in codesys.</p></div>

<div class="markdown_content"><p>Hello everyone ,<br/> I updated to version 4100 and since I see a fault in the GPIOs of the raspberry:<br/> I am using a raspberry GPIO to pulse to an external hardware watchdog.<br/> the pulse is managed directly by raspbian:</p> <p>import RPi.GPIO as GPIO<br/> import time<br/> PULWD = 16 # BCM / GPIO<br/> GPIO.setwarnings (False)</p> <p>GPIO.setmode (GPIO.BCM)<br/> GPIO.setup (PULWD, GPIO.OUT)</p> <p>while True:<br/> GPIO.output (PULWD, 0)<br/> time.sleep (0.5)<br/> GPIO.output (PULWD, 1)<br/> time.sleep (0.5)</p> <p>so far this has always worked with all other versions of codesys.<br/> since the update, as soon as my codesys program is in RUN on the raspberry, the GPIO signal is completely random.<br/> when the program is in STOP, the GPIO signal flashes again normally ....<br/> I am not using any raspberry GPIO in the codesys program.</p> <p>Thanks for your help.</p></div>
