Assigning a Serial Bus Address to a New BIU

The first step in configuring a new Bus Interface Unit is to assign its Serial Bus Address (block
number) on the Program Block ID screen. There are 32 available addresses (from 0 to 31) on a
bus. One is needed for the Hand-held Monitor; typically, this is 0. Another is needed for the Bus
Controller. Typically, this is 31 (30 or 31 for redundancy systems). A Bus Interface Unit is
usually assigned a Serial Bus Address from 1 to 29 or 30. Duplicate Serial Bus Addresses disrupt
communications and are not permitted.

BLOCK NO. ?

1. Pr ess F2 (Block). Then, enter the Device Number (1-30). For example:
PROG BLOCK ID
I/O ?- ??
BLOCK NO. 14
blk nxt
If you make a mistake, press F2 again, then enter the correct number.
2. If you are configuring th e Bus Interface Unit on an operat ing bus, when you press the Ent er
key, an error message app ears if the number has been used for another device. If the Bus
Interface Unit is not online, be sure to assign a unique Serial Bus Address, or there will be a
conflict when the Bus Interface Unit is powered up on the bus.
