Hello,
I'm trying to take input from a group of load cells and compute throughput (i.e. tons/hour, kg/hour, etc.). Currently the load cells are wired in to a common load cell transmitter that then outputs the current weight on a 4-20mA scale to the PLC. The transmitter itself is pretty bare-bones and is not capable of rate of change calculation.
I'd like to manipulate this signal to approximate throughput. Before I start trying to reinvent the wheel, I wanted to see if there was an existing solution to this issue. I'm using Studio5000 and I see that there's a built in TOT block, however this seems to do the opposite of what I'm trying to accomplish. If I understand correctly, TOT integrates a rate to come up with a total for a given period of interest. I believe I need to differentiate in my case.
Major beginner here so any help is appreciated. Thanks for your time!
