 Feeding/looping through via separate cables
The supply voltage for the electronic components/sensors and PROFIBUS-DP are
fed to the first ET 200X and looped through to the downstream ET 200Xs via two
separate cables.

 Feeding/looping through of PROFIBUS-DP via 1 cable
The supply voltage for the electronic components/sensors is fed to each ET 200X
separately. PROFIBUS-DP is fed and looped through to the downstream ET 200Xs
via a common cable.
