ABB NDBU-95 NDBU - DDCS branching unit

Chapter 1 - Settings on NDBU-85/95 boards

NOTE: 

DC drives (e.g. DCS 600 products) use 10 MBd optical transmitters/receivers. · ACS 600 products use 5 MBd as well as 10 MBd optical transmitters/receivers. · Mechanically both types are identical i.e accept the same cable connectors. · Mixing 5 MBd and 10 MBd is not possible. · With 5 MBd optical components only plastic optical fibre cable (POF) can be used.

Chapter 2 - Address Hierarchy of Branching Units Type NDBU-85/95

Address hierarchy

When a system is built up, the branching units addresses must be set according to a certain hierarchy. Principal is that the closest branching unit to PC must always have biggest address number. (The addresses are set by dip switch S1 located on the branching units type NDBU-85/95; see chapter 1, section “Layout of branching units type NDBU-95”).
