6.4.3 Method ReadSafetyDiagnostics of the SafetyProvider

returns both the input and output parameters of the last call of the Method ReadSafetyData . Additionally, a 2-octet sequence number is added to the Diagnostic Interface , allowing ... missed calls due to polling. The sequence number counts the number of accesses to ReadSafetyData . A best practice recommendation is to store all input and output parameters if SComErr_diag
