January 2012 3.4 HSCI 169
The following table shows the maximum permissible number of individual
HSCI participants:
The order of the HSCI participants at X500 of the main computer can be freely
chosen. Each HSCI participant is assigned its HSCI address based on its posi-
tion in the HSCI chain:
• First device after the master (main computer): Bus address 1
• Second device after the master (main computer): Bus address 2 etc.
The main computer selects a master controller unit, based on the position of
the controller units in the HSCI network. The first controller unit in the system
(nearest the main computer) becomes the master controller unit.
