I programed the mov and tried to get the HHV value fornula to work but no luck as my knowledge of the syntax is not good enough and it just kept on giving me an error message. But at least I have a 21d MOV exit see attached. Thanks for your thoughts it will work in some situations but the existance of a short signal would be better. I'll keep experimenting as I dont want discrete values (like the 80proposed)if possible Thanks again Mike ![]() |
