2.8 Activating transformation machine data via part program/softkey
2.8.1

Function

Transformation MD can now be activated by means of a program command softkey, i.e. these
can, for example, be written from the parts program, thus altering the transformation
configuration completely.
Up to ten different transformations can be set in the control system. The transformation type is
set in the following machine data:
MD24100 $MC_TRAFO_TYPE_1
up to
MD24460 $MC_TRAFO_TYPE_10.
Characteristics
The transformation MDs are activated using the "Setting machine data effective".
The protection level is now 7/7 (KEYSWITCH_0), which means that data can be modified from
the NC program without any particular authorization.
If the machine data are activated (regardless whether via the NEWCONF NC program
command, the HMI or implicitly following reset or end of program) - and no transformation has
been selected (activated) - then the machine data listed above can be altered without restriction
and then activated.
Of particular relevance is that new transformations can be configured or existing
transformations replaced by one of a different type or deleted, since the modification options
are not restricted to re-parameterization of existing transformations.

Constraints

Changing machine data
The machine data which involve an active transformation may not be altered; any attempt to do
so will generate an alarm.
Generally, these are all machine data, which are assigned a transformation via the associated
transformation data group. Machine data, which although contained in the group of an active
transformation, but are not used, can be changed (however, this could hardly be considered an
operation that makes sense). For example, it would be possible to change machine data
