axis.address is only available after printing an axis
OPTICS [1]: llrz2.address
!!! === AttributeError: 'Axis' object has no attribute 'address' === !!! ( for more details type cmd 'last_error' )
OPTICS [3]: llrz2
Out [3]: AXIS:
...[snip]...
OPTICS [4]: llrz2.address
Out [4]: 7
Is it a feature or should I be using llrz2.config.get('address') instead ?
