Connect 4 (up to 6) Load cells to a S7-1200 PLC through a Modbus transducer

Dear Sir,

Hi

Thanks for sharing your project with us it was very helpful.

I have a similar project in which i have to connect 4 (up to 6) Load cells to a S7-1200 PLC through a Modbus transducer (made for load cell). In this project i have to read some values from the transducers (like weight...) and write some values (for calibration of the weighing system). Can i use your procedure? It's for a cement batching plant. It has cement weight, water weight, additive weight (maybe 2), and aggregate weight.

I need to weight these and open or close gates or valves or run a conveyor belt. how fast can i weight this 4? can it be somehow seamless and feels like they are at the same time? I know how Modbus-485 works. let's say it's about 2000kg aggregate, 400kg water, 500kg cement and 50kg additive.

thanks for your help
