PI p

Hello everyone,

I have recently joined in a product based company as a PI developer, the project has already gone live and iam going to be monitoring it in future, so iam trying to go through the interfaces and get familiar to it, i under stood most of it but i have got a small doubt when i have seen interface determination and cliced on the Operational Mapping it showing some thing like parameters and values. i just want to know what are they and how are they useful.

Thanks in advance
