The activation with respect to a machine data specifies in which status of the
NC a change of a machine data becomes active.
Activation categories are:
S
Power ON
S
Reconfiguration
S
Reset
S
Effective immediately.
Setting data are system variables telling the NC the current machine properties.
The identifier of a setting data is subject to the scheme:
$ S k _IdentifierString
The letters/characters have the following meaning:
S
$
System variable
S
S
Setting data
S
k
Component
k identifies the components of the NC parameterizing the appropriate machine
data:
S
N
NC
S
C
Channel
S
A
Axis
In contrast to machine data, changes of setting data always come immediately
into effect.
The machine data are divided into the following areas:
