We are looking at an application where we will be filling a container by weight. The current system uses a large hopper on top that feeds two vibratory feeders. Then a small hopper with a scale to do the weight. This should be simple to do in a plc however they are currently using a scale system. I am thinking their scale system is running some kind of PID to slow down the feed as it gets near the setpoint. How important is the scale controller? Can I do this in the plc? I have never done this type of application but it looks like I should be able to do it in a plc.
Here is the spec's as I know them.
Part weight 3400 grams
Fill time 30 seconds
+/- 2 grams
