•
To one basic system element
CP-2017/PCCX25 one bus line with max.
16 peripheral elements can be connected
•
The slots for the redundant BSE-pairs are
predefined, in fact: 1+2, 4+5, 7+8, (10+11,
13+14 only in 17 slots mounting rack)
•
Depending on the slots of the basic system
elements the socket connectors for the
electrical Ax peripheral bus have to be
selected (for example: slots C1 and C2
socket connectors AXPE-C1 and AXPE-C2)
•
In configurations with optical remote
SICAM TM PEs 1000 µm-fibre cables cannot
be used!
•
Redundant BSEs have to have identical
configuration and identical functionality
•
Each bus interface module CM-0842 has to be
supplied separately (18 VDC...78 VDC)
