SICAM RTUs, SICAM AK Redundancy
Edition 10.2016, DC2-026-2.07
1.2.1.2 SICAM AK - SICAM TM PE, Electrically Connected
Base unit SICAM AK to peripheral elements SICAM TM, electrically connected.
•
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)
•
Redundant BSEs have to have identical
configuration and identical functionality
•
If peripheral elements are equipped in the
base unit SICAM AK then those can be driven
either by the singular BSE CP-2014 or by the
redundant BSEs CP-2017
•
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 C4 and C5
socket connectors AXPE-C4 and AXPE-C5)
•
The bus interface modules CM-0843 are
supplied by the power supplies PS-663x.
The power consumption of the CM-0843
(see technical data in data sheet) has to be
considered on the PS-663x
