SICAM RTUs, SICAM AK Redundancy
Edition 10.2016, DC2-026-2.07
1.2.1.4 SICAM AK - SICAM TM PE, Optical, Red. BSE + Red. Ax-PE-Bus
Base unit SICAM AK to peripheral elements SICAM TM, optically connected, redundant basic
system elements and redundant Ax-PE-Bus.
•
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)
•
Attention: Break of an FO-connection leads
to a failure of the peripheral elements
PE-6412 until the redundant basic system
element duly assumes the function
During this time connection to the peripheral
elements PE-6412 does not exist
•
