Safety integrity level


Safety principles and system architecture

A safety relevant hardware of K-2002 was designed according to an european standard EN 50129, a safety relevant software according to EN 50128. A technical safety of K-2002 is based mostly on a redundancy 2 out of 2. With this architecture are designed all safety relevant computer circuits. All electronic circuits are backed up due to an ultimate system availability, which is at least 99,99%. An architecture of the whole system is therefore 2 times 2 out of 2.

Operation mode

A hot or a cold standby.
