Motion Object Attributes

The Motion Object Attributes are included in this manual to provide you with
a greater understanding of how the system works. Your familiarity with these
attributes allows you to take greater advantage of the flexibility inherent in the
RSLogix software. The Axis Object Interface Attributes comprise all the axis
object attributes that are used by RSLogix 5000 to support the interface to the
axis object including configuration attributes used in customizing many of the
configuration screens and motion instructions that operate on the axis object.

Object Support Attributes

The following attributes are used by software to establish the interfaces and
structure of the motion axis object instance.

Axis Instance

The Axis Instance attribute returns the instance number of an axis. Major fault
records generated for an axis contain only the instance of the offending axis.
This attribute is used to determine if this was the offending axis; i.e. if the
instance number matches.
