There are many tag numbers in the flowchart, and these tag numbers contain many letters

The “first character” in the tag includes the “initial variable” and “correction”; what is the purpose of the “correction”? In the tag name, the meaning of \"the first character\" is replaced by the meaning of \"initial variable\". Are all the subsequent letters to be read using the meanings represented in the “readout or passive function list”? ”What do the readout or passive function list items “additional output function” and “correction” mean?
Measured/Initiating Variable, the variable being measured/the variable that triggers something； Readout/Passive Function, readout/no functional role ； Output/Active Function, output/functionality ； Modifier, modify ； Note to the poster: Initiating Variable refers to a variable that triggers something, not an initial variable ； Modifier is an adjective, not a correction. If the initial letter is accompanied by a modifier, they together form a term; for example, TD denotes temperature difference. If there is no modifier, it represents the variable being measured or the variable that causes a change, for example, T denotes temperature ； When the readout function is accompanied by modifiers, it provides a detailed description of that function; for example, PIAH where H indicates an alarm for high pressure limits. If no modifiers are used, such as PIA, it only denotes a pressure alarm without specifying what type of alarm it is.
