In one or two previous posts I have been trying to sort out a meterage counter for a polythene production machine that can make reels of film anywhere from a few hundered metres to 31000. The line speed can be anywhere from 30 to100 metres per minute. I also need to interface to an ancient Texas PLC. This part has been easy so far, what I really, desperately need is an *** proof way for a machine operator to enter the preset metres into the counter. (Hence the reason for the wish list post.) If anyone has any suggestions or can point me at an exsisting post I would be eternally grateful.
