cnc_rddynamic2_ActS - This tag reads various dynamic data from the CNC machine, such as actual feed rate, spindle speed, and axis positions. It is an improved version of the cnc_rddynamic function and can read more comprehensive data
For the rest of the other tags, follow the help file
Essentially, the main difference between the last two tags lies in the type of data being read (1 for position and 2 for speed).
