Dear Sir,

Hi

Thanks for sharing your project with us it was 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). 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 feel somehow seamless 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. and we should do everything in 70 seconds (including discharge of mixer).

how did you solve your problem? can you help me ?

thanks for your help
