DC2-026-2.07, Edition 10.2016
1.3.1.2 Redundant AUs, Voting by SCA-RS, Distance up to 200 m
Implemented with the third party product MOXA Nport Server:
•
Redundancy synchronization of function
diagram and of the periphery is executed by a
high speed link
•
A high speed link is essential with singular
periphery
•
SCA-RS is connected to SICAM AK via the
socket connector SYS-IO on the SICAM AK
•
The electrical connection between Ethernet
and SICAM RTUs component or between
Ethernet and MOXA-Server can be up to
100 m
•
Depending on the slots of the basic system
elements the socket connector for the H.S.L.
connection has to be selected (e.g. slot C0
socket connector HSL-C0)
The following socket connectors are
available: HSL-C0 and C1, in the small rack
CM-2832 and additional C4, C7, C10, C13 in
the large rack CM-2836
•
The MOXA Server can be supplied by the
Power Supply HSA 50S24-P from MTM
Power (item number: MTM+HSA50S24-P)
