Good morning guys,
I have a machine that fills bags of prepared food at a variable speed, and a machine that checks the weight of the bag. What I am trying to do is to use the weight checker to speed up or slow down the bag filling machine so that it will automatically adjust the speed for the set weight.
The idea is that both machines have Allen Bradley controllers with ethernet comms and I use either on board PLC for the control or i use an external one i will be adding.
I'm trying to think how i would do this in ladder logic and a PID loop comes to mind but I wouldn't even know where to start to set it up...
Help/Ideas?
