7.2.3.2 Calculation of the SPDU_ID_1, SPDU_ID_2, SPDU_ID_3

Presentation of the SPDU_ID SPDU_ID_1:= SafetyBaseID (octets 0…3) XOR SafetyProviderLevel_ID (octets 0…3) SPDU_ID_2:= SafetyBaseID (octets 4…7) XOR SafetyStructureSignature (octets ... differs, but SPDU_ID_2 and SPDU_ID_3 do not, the SafetyProviderLevel does not match. By these rules, there is a very low probability (<10-9) that
