AADvance Safety ManualFunctional Requirements ChecklistDescriptionIs the definition of each of the required functions complete?Are the interfaces, signals, and data associated with each functionclearly identified?Where a 'tag referencing' scheme is used for these signals, has asummary description of the naming convention been provided tofacilitate an understanding of the role of the signal?Have the performance requirements for each function, orcollective functions, been defined?Have the operating modes of the EUC, process or plant beenclearly defined?Have the functions required to operate in each plantoperating-mode been identified?Have the transitions between each plant operating-mode beendefined? Have the functions necessary to effect these transitionsbeen established?Yes/NoSafety Requirements ChecklistDescriptionHave all of the functional requirements been allocated a requiredsafety requirements class?Has the safety-related timing for each safety-related function,including process safety time (PST) and fault tolerance period,been established?Have the safety requirements been approved?Are there clear definitions of the external interfaces involved ineach of the safety-related functions? (These may already bedefined in the functional requirements).Is there now sufficient information to understand how the plantshould be controlled safely in each of its intended operatingmodes?Yes/No6-2 Document number 553630 Issue 7: February 2010
