Formulates the appropriate requirements for safety instrumented systems (SIS) that must be met when an ISMS is set up, where SIS comprises the sensor, actuator, the safety programmable logic controller (logic system), the application programme and the associated engineering. In Edition 2023 the Baustein carries 12 requirement numbers, 12 of them live: 3 Basis requirements (B, MUSS, to be fulfilled first and without exception), 8 Standard requirements (S, SOLLTE) and 1 requirements for elevated protection needs (H). It is applied to an IT system in modelling order R2. The requirements property on this node lists every requirement by number, title, level and responsible role, so a requirement is cited as IND.2.7.A<n>.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
