Problem of Machine Connectors

► Individual and hard-coded transformations

► Transformation knowledge is hidden in the machine connectors

► Current solutions cannot be adapted easily

Novel Integration Solution

Various machine protocols

Graphical transformation

editor

Storage of transformations
