Ring structure of the optical transmission in the PPC link
Several PPC motion controls can be combined to create one PPC link
with which the following axes can be assigned to different master axes.
This combination of PPC motion controls is accomplished with the help of
PPC plug-in card DAQ. All DAQ boards are connected with a fibre-optics
cable (LWL) ring thereby creating the PPC link.
Each PPC needs a different link address.
The PPC link can be built on a simple or double fibre-optics cable ring.
