Effective Transformations Upon Reset; Persistent Transformations - Siemens SINUMERIK 840DE sl Function Manual

Transformation type "TRACON_K" (Page 281) is used in combination with kinematic chains in
order to chain an "Open Architecture (OA)" transformation with one of the standard
transformations. More detailed information is provided in the "Open Architecture (OA)"
documentation.
Further information
An exhaustive description of the chaining of transformations without kinematic chains can be
found in Chained transformations.

Effective transformations upon reset

Active transformation upon reset
The kinematic transformation that is in effect during a reset is defined via the machine data
$MC_TRAFO_RESET_NAME.
If no name has been defined for $MC_TRAFO_RESET_NAME,
$MC_TRAFO_RESET_VALUE is active or no transformation is active upon reset. The contents
of this machine data specifies the number of the conventional transformation to be activated.
Conventional transformations are not defined via kinematic chains, but via machine data.
Furthermore, the machine data $MC_RESET_MODE_MASK Bit 7 acts as it does for
conventional transformations. If bit 7 is set, the active transformation is retained after the reset
or the end of the part program.
4.1.10

Persistent transformations

Persistent transformation
A persistent transformation is a transformation which is retained even when another (different)
transformation is switched off with TRAFOOF. This transformation is identical to the
transformation that is in effect during the reset (Page 271).
If a different transformation is selected, the persistent transformation is replaced by the newly
selected transformation. The newly selected transformation is NOT concatenated with the
persistent transformation.
