7.2.3.5 Signature over the SafetyData Structure (SafetyStructureSignature)

over SafetyStructureIdentifier (encoding: UTF-8), SafetyStructureSignatureVersion and the sequence of the DataTypeEncodingIDs . After each DataTypeEncodingID , a 16-bit zero-value (0x0000) shall be inserted. All integers shall be encoded using ... 0x6f 0x74 0xc3 0xb6 0x72 0x68 0x65 0x61 0x64 SafetyStructureSignatureVersion := 0x0001 1. DataType Int16 : ( DataTypeEncodingId = 0x0004), // see 6.2.5 2. DataType Boolean : ( DataTypeEncodingId = 0x0001), 3. DataType Float : ( DataTypeEncodingId =0x000a) SafetyStructureSignature = = CRC32
