Standard Deviation Block
We are using PLC_AC500_V2 (PM583-ETH),need calculate average value for density of alcohol from process start to process end,so which block can used to find the mean density of the process.

Hi
I don't think there is a specific block for what you asked for, I think it is more correct to identify the physical relationship between the expected result and the process variables in place.
When you have the math / physics / chemistry relationship of your process, you have to translate it into logic, using the most correct form - perhaps the ST language -.
Each process has multiple cases and variables and having a library with all the blocks already packaged seems to me very difficult to find, perhaps in taylor-made controllers but certainly not in an AC500 CPU.

The OSCAT Library for Codesys has the building blocks for doing this. https://www.tecomat.com/uploads/files...
Once you've decided how to store the required sample data for your batch without running out of memory space, calculating the Average should be trivial.
