Hallo again, Okay this time in english. Transport beld goes 40 meters/minute (average speed, it's adustable to the proces) packetlenght = 18 cm max 140 packets per minute (Between 110...140 packets/minute depending on the proces) So, with the maximum speed of 40 mtr/min = 66 cm/sec the packages are 28 cm seperated from each other. The space between the barcodescanner and the cilinder is aprox. 70 cm. So lets say that between the scanner and the cilinder 3 package fit. I need to know how to program this problem. example: #begin wait scanner = on period = timer + speed (depending on beldspeed) #cilinder if period > timer then goto cilinder cilinder = on pause 2 cilinder = off goto begin In this example one package will be trow out. but if package 1,2,4,6,7 must be trow out, this little program will not work. I'll have constantly poll the barcodescanner, and add a time to this trigger. And there is my problem, when I'm waiting for the timer to activate the proces, I cannot poll my triggerinput. The chance that I miss the trigger or see it to late is to big. So I dare you......
