•
SCA-RS is connected to SICAM AK via the
socket connector SYS-IO on the SICAM AK
•
Redundancy synchronization of functional
diagrams and periphery is carried out via free
selectable communication (Ethernet preferred,
select transfer as fast as possible); a separate
interface is recommended
•
The electrical connection between Ethernet
and SICAM RTUs component or between
Ethernet and MOXA-Server can be up to
100 m

redundancy synchronization
preferred via Ethernet
•
The protocol element for redundancy
synchronization must not be placed on the
M-CPU but should be necessarily situated
on the synchronized C-CPUs
•
In this configuration only redundant
periphery is possible
•
ATTENTION: Time-critical applications are
not possible in the FUD; minimal cycle time:
1 ms
•
The MOXA Server can be supplied by the
