FOUNDATION Fieldbus has always adhered to the international standard,
and the SIF is no exception. FF-SIF meets the IEC 61508 standard for functional
safety systems up to SIL 3, and allows users to build safety systems
that adhere to the IEC 61511 standard for functional safety in the process
industries. The protocol has already received TÜV approval, and suppliers
are going to start submitting their products for TÜV approval over the next
year. This means that we should see actual products that are certified by
TÜV available commercially some time in 2010.
