Hello everybody,
New guy here. I have been a long time reader but finally found the end of the internet looking for the anwser to my question.
My current system is a dry product pneumatic conveyance system (4") that uses a rotary airlock to feed the product in closed loop system (product can return to feed tank).
The problem: System is not smart. It just turns the Rotary airlock (vfd) on full speed and when pressure spikes (15psi) it stops feeding. Waits for the pressure to fall (10psi) then hammers at it again. the result is a system that is probably not delivery at maximum eff.
Current hardware: CLX-L62. Pressure sensor. VFD on airlock. Feed tank weight, delivery tank weight.
I would like to figure out a way to use some sort of "smart" method to control this where I can feed the product at some speed (or maybe vary it slighty based on pressure) to maintain a somewhat level pressure below the set amount.
I am new to 5000, plcs and process control. I have a good handle on how to make program changes within the safety aspects of the system. What I dont have is the ablity to use the process features of function blocks. (I understand fucntion blocks). Example, PIDE, POSP, SRTP and so on.
I have probably not given enough information but apprecaite any help yall are able to offer.
