**It is given int register from 0-47**

X: [0…23] - The lower range of the integer input registers is reserved for FieldBus/PLC interface usage.

This is correct.  
And you can use the URscript function read\_input\_integer\_register() to access all of them.  
This is probably an error in the documentation you are using. This is the documentation I’m using and it says “Address of the register (0:47)”
