Redundant application
SINAUT ST7sc also allows the connection of a redundant client system. In this case, two
ST7sc systems would need to be used. They transfer data received from the stations to both
clients in parallel and independently of each other and accept data from them that needs to
be sent to the stations.
The redundancy intelligence is at the client end:
● It ensures correct evaluation and comparison of the parallel transferred data.
● It transfers data to be sent to the stations only once to one of the two ST7sc systems so
that there is no duplicate transfer.
Configuration
The configuration of ST7sc is performed using the ST7sc Config Tool that is supplied on the
ST7sc software CD.
The documentation for ST7sc and the Config Tool is also on this CD.
