hello,
I am trying use raspberry pi3 +b board. I make codesys test program. Program send to raspberry board run system running. I connected Led cathode to PIN 6 (GND) and led anode to PIN12 (PGIO18). Then I set PGIO18 TRUE level, but led doesn't shine. I don't know where are my mistake. Maybe could give me advice, how solve this problem. I think problem is with raspberry, but I write python program

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
GPIO.setup(12,GPIO.OUT)
for x in range(0,10):
    GPIO.output(12,True)
    time.sleep(1)
    GPIO.output(12,False)
    time.sleep(1)
GPIO.cleanup()

Led is blinking.

I attached all my test project.

Hi,
just try to revert your project to non device application... then it might work.
