cement batching plant

Dear Sir

Hi,

Thanks for your information. I have some questions in regard of cement batching plant if you can help us.

For weighting system we use 4 load cell transducers with Modbus RTU output to connect them to s7-1200. Is it possible? I mean is it accurate and fast enough for reading weight?

For aggregate gates we use pneumatic air cylinder to open or close them? i wanted to know is that all that we have to do to control the weight? to have an approximate weight with max 10 kg error?

or should we design a PID loop in PLC to close the gate?

Thanks in advance for your time
