8 Station variants8.6 CAN objects for station variants368 Gateway XN-312-GW-CAN 06/16 MN050003-DE www.eaton.eu8.6.4 Available Modules (internal) (Object 0x4008)Object 0x4008 is addressed exclusively from the IEC library. While the PLCuses object 0x4007 to tell the gateway what the full configuration is, thegateway uses this information in order to identify physically missing nodesand substitute them when dealing with the field bus. Object 0x4008 repre-sents a bitmask used to identify, by means of a double word, which of theindividual XN300 slice modules in object 0x4007 are present and which areabsent..Design of the data bytes:Feature Description / Value EDSType name INTERNAL_ML_MC [4007]Parameter name=INTERNAL_ML_MCObjectType=0x8SubNumber=1[4007sub0]Parameter name=INTERNAL_NM_MCObjectType=0x7DataType=0x0005AccessType=rw[4007sub1..32]Parameter name=INTERNAL_NM_MCObjectType=0x7DataType=0x0006AccessType=rwPDOMapping=0Description INTERNAL_ML_MCObject Code ARRAYMapping SDODefaultData type UNSIGNED16Sub index 00 count of modules for full configuration01 first module ID of full configuration02 …FE hex next module ID of full configurationAccess roDefault value 0000 hexFeature Description / Value EDSType name INTERNAL_BM_MC [4008]Parameter name=INTERNAL_BM_MCObjectType=0x7DataType=0x0007AccessType=rwPDOMapping=0DefaultValue=0Description INTERNAL_BM_MCObject Code ARRAYMapping SDODefaultData type UNSIGNED32Sub index 01 … FE hexAccess rwDefault value 0000 hexData bit Desig-nationDescription0… 31 0 = Module from full configuration not found in station variant1 = Module from full configuration found in station variant
