DCS employs quality inspection; how should it be configured to remove the impact of quality variations and to measure actual quality changes?

I would like to ask: For a central control DCS that utilizes quality monitoring, how is it configured to perform quality subtraction and measurement of quality changes? Which functional blocks are used for this purpose? Thank you!
Hello, if this is a weighing scale, the requirements you mentioned are not functions of DCS; you should focus on the scale itself, as it is DCS that receives the analog signals sent by the scale
By the peeling function you mentioned, can I understand it as setting a tare weight to display the gross weight and net weight? To implement this function, all that’s needed is one subtraction operation. The variables required include external variables such as the weight reading Weight_real, an input variable for estimating the tare weight Computed_weight_real, and an output variable for the net weight net_weight_real. The calculation is net_weight = Weight – Computed_weight; These relevant variables should be displayed on the screen.
It’s much more convenient to do it directly on the scale and then send the data to the DCS, or set the variables in the DCS and use the arithmetic function modules for the calculations
