3.3.1
Master Connection to a Redundant PROFIBUS Power Hub System
•
Normally, diagnostic information from the diagnostic module HD2-DM* is
transmitted via the gateway. You do not need to connect neighboring Po-
wer Hubs.
Alternatively, you may bypass the gateway and transmit the diagnostic in-
formation via a separate bus. Only in this case do you need to connect
neighboring power hubs using the ACC-MB-HDC diagnostic link cable.
The last Power Hub in a row has to be fitted with a final motherboard link
(see figure 3.1).
