I have a drum that I have to display the RPM. It has 8 magnets and a Hall sensor. I can convert the 8 signal to 1 rpm with linearization, but how do I display it as rpm instead of just an increasing number until I reset it? Any help would be greatly appreciated. Thanks!

Figured it out. I had MI16 with power up condition checked with 100. Unchecked it and it works fine. Thanks again!

It worked great, thank you! The only problem I have when I restart the PLC I have to re-teach the scale for the 100lbs.

Thanks! I will try it tomorrow.

I don't have a problem showing the weight. The display is configured 4 digits, 0-1000lbs. What I can't figure out how to set a new Tara. Example if I replace a part on the machine that will make it 5lbs lighter, the scale will read 0000 instead of -0005lbs and I have no way to make that a new 0000 point other than re-calibrating my amplifier.

No. I have 3 load cells connected to an amplifier sending out 0-10V. I am using the V200-18-E3XB. I have the display setup and it shows my weight. I am using the enable charge, full and empty settings and everything works fine. The problem I have is that I want to set 1V (410 counts on X2) as my 0 lb on the display so if the scale goes out of calibration (below 410 counts) I would see it as - *** lbs on the display instead of just showing 0lb. I have this working on a different machine, but that uses an omron plc and I have no access to the program to figure out how they did it. If I could set Y1 to 0 then it would be my 0lb on the display (tara).

I am working on a project that has a scale to load the machine. If the feeder is less than 350 lbs the operator is able to turn on the blower to fill more material into the feeder. When the weight reaches 350lbs the blower stops and the feeder automatically loads the material into the machine. When the scale is empty (0 lbs) it stops the loading and goes to the next step. I am having trouble to set the TARA and the 100 lbs calibrating point. I am trying to "store" linear X to Y1 as a 0 (tara) point and use the math functions to set/teach 100 lbs when I put my 100 lbs weights on the scale. Neither works so far. I would greatly appreciate any help with this. Thanks! scale sample.vlp

Got it, thanks!

So if I leave those steps at 0 second then the drum stops. Now when my scale reaches the desired weight the scale rung needs to send a mb to "next step" on the drum to run again, right?

Yes. I have a ~40 steps procedure that requires a series of timers, but some steps requires an input from a scale ( weight reached) to advance to the next drum step.

Can I mix inputs into the drum sequencer or timers only? Thanks
