I am trying to track some boards using FIFO instructions in my laser routine along with my main routine. I have tried everything... I am using Studio 5000 Logix Designer and I am hoping someone can look at this and tell me what it is not working. We are trying to drop out wet boards at one location along the chains and then drop out other boards depending on thickness at another location... I am not sure how to attach my file since it is rather large....
