In IEC, you not only assign a Terminal number to each Terminal (including each level in a 2/3 level terminal block) but you also can assign a nunber to each side of the terminal. Thiat information is be stored in the X#PIN## attribute.
For example, say we assign the top screw of a terminal (we will call this TB10) to 1 (X2PIN01=1) and the bottom to 2 (X8PIN01=2).
Then, when running a To/From report, it would report a wire connected to the top of the terminal block to TB10.1 and to the bottom TB10.2.
This allows the designer to be very specific as to where a wire is landed on the terminal. (Since you can draw the schematic so that it depicts exactly how the system is wired.)
Also, the X# value represents its position on the block
X1 is Right.
X2 is Top
X4 is Left
X8 is Bottom.
