What do letters such as UI in a PID diagram mean? Is there a standard list?

Where’s the picture? Is there visual evidence to prove it? Otherwise, how else can it be explained?

The letter U denotes multivariable, or multifunctional. UI stands for multi-variable indication. That is, it is not indicated by a single variable.
