Loadcell with S7 1200 and HMI


Thread Starter


Dear All,

I am using a loadcell (0-10 kg). and I get analog values at a level of mV and then using transmitter. I get the new analog values at the level of V(mV-->V), and then i enter the new analog value to the analog input of s7 1200. without using any indicator, i want to create zeroing and calibration function and manage the functions on the HMI screen with using buttons.

Zeroing function is not for to get tare weight. it is to zero small mistakes (like 0.1 kg) that seen on the screen.

I am confused to start it. If you have any ideas, sources or works and share with me, i would appreciate. Thank you .
