The Mark VIeS is the safety platform of the mark VIe, and it has been certified to be SIL3 (controllers and IO packs). It can be a TMR, DUAL, or SIMPLEX configuration. But what i want to understand deeply is: does this safety platform has to co-exist with a control platform (mark VIe) in the same time or it can be a stand-alone control and safety system (Turbine control) in the same time? (we have to the same IO packs regarding their role, but they are safety certified).
thanks in advance
