Axis container
An axis container is a circular buffer data structure, in which local axes and/or link axes are
assigned to channels. The entries in the circular buffer can be shifted cyclically.
In addition to the direct reference to local axes or link axes, the link axis configuration in the
logical machine axis image also allows references to axis containers.
This type of reference consists of:
• Axis container number
• A slot (circular buffer location within the corresponding container)
The entry in a circular buffer location contains:
• A local axis
• A link axis
The axis container function is described in

1.2 Coordinate systems
MCS
The machine coordinate system (MCS) has the following properties:
• It is defined by the machine axes.
• The machine axes can be perpendicular to each other to form Cartesian system or
• The names of the machine axes can be defined.
• The machine axes can be linear or rotary axes.
BCS
The basic coordinates system (BKS) has the following properties:
• The geometry axes form a perpendicular Cartesian coordinate system.
• The BCS is derived from a kinematic transformation of the MCS.
BZS
The basic zero system (BZS) is the basic coordinate system with a basic offset.
