In the exaquantum China Construction tag template, under the tag type category, what types of points are required for opc, man, calc, and shortcut respectively?

I haven’t worked with this for a long time, so I can’t remember clearly: OPC is for communication points, man is for manually entered points, calc is for calculation points; shortcut refers to other points within the system. I’ve kind of forgotten how this works
OPC: Signals received via OPC communication (including DCS/PLC...); MAN: Manually entered values (can also be used to store the results of calculations); calc: Used to perform calculations by invoking other points in Exaquantum; shortcut: Refers to other points in Exaquantum; I often use it in function block templates, allowing all calculation operations within those templates to start with a certain prefix, which facilitates the writing of function blocks.
