Please help me to split information according set bits in Number XTR3056. More bits can be set together.
The best way for solution I would prefer is do it directly in variable Number 3056 acquisition python script.
Thanks for help.

You could use Transformations or Profiles, e.g. 8 JavaScript Transformations (see Bitwise AND (&) - JavaScript | MDN). Of course, there might be a more elegant way to dissect your Number …

Thanks. I solved it directly in python script with logical AND for separate bits. Example python code:

s0 = openhab.get_item('XTR3056_0')
if (XTR3056&1 != 0):
   s0.state="CLOSED"
else:
   s0.state="OPEN"

s0 = openhab.get_item('XTR3056_1')   
if (XTR3056&2 != 0):
   s0.state="CLOSED"
else:
   s0.state="OPEN"

s0 = openhab.get_item('XTR3056_2')      
if (XTR3056&4 != 0):
   s0.state="CLOSED"
else:
   s0.state="OPEN"
