Axis Attributes

The axis attributes contain up-to-date information about the axis as follows:
the dimensional unit selected for position encoding,
whether the required position is reached or not,
(this signal is also output via a digital output of the IP247),
whether the reference point location is synchronized or not,
whether the teach-in mode is on or off,
the existence of the reference point,
the existence of the machine data on the axis,
the axis status ("finished" or "running").
The axis attributes are passed onto the control system via FBI 64 in the checkback signals. (DL

Apart from the axis attribute which indicates whether the required position has been reached or
not, all axis attributes are indicated directly in the test axis selection and modes display in
COM247 (=> Section 5.8 "Test").
