Hi Everyone i have attached a file below kindly have a look. so the problem i am facing here whenever the binary bit B3 goes on it goes into integer file N20 which in return set msg window on. once the msg is one the output on other logic goes on. but when i turn the binary bit B3 off the integer N:20 stays off but nothing happens in msg window it's done bit stays on and the output on the other logic stays on. how can i deal with this. i want the msg window to send the msg according to the state of binary bit B3
