I am experimenting with the BSL instruction in LogixPro and have run into a
problem. The goal of my program is as follows: track bad products on a
packaging line and reject them with a solenoid valve output when they reach
a certain position in a bit shift. The output solenoid (O:2/0) is to stay
on for 1 second, regardless of the activity of the product sensor (I:1/0).
My problem is that when the 'bad product' bit reaches the reject position
(N7:1/14), the timer output continously runs and resets because the sensor
input is staying on for some reason, even though the sensor is not
activated! The program is ok once I:1/0 is activated and a 0 is placed in
N7:1/14. Any ideas?
Any help/advice you can give is appreciated, thanks!
