Theoutput data to all SmartWire-DT modules is grouped in instance 100. Theinputs of all SmartWire-DT modules are grouped in instance 101. The objectlength varies and depends on the number of SmartWire-DT modules andtheir data volumes. The maximum object length is 496 bytes for eachinstance.Overview of functionsClass AttributesCommon ServicesTable 10: Common ServicesClasses/InstancesAttribute/Services &ValueClassesAttributes 0x01, 0x02, 0x03, 0x04, 0x06, 0x07Services 0x0EInstancesAttributes 0x03, 0x04Services 0x10 (for instance 100 only), 0x0EFor explanations regarding the services, see Tabelle 6Attribute number Attribute Name Get/Set Data type Description &Value1 (0x01) REVISION G UINT Class version 0x00 022 (0x02) MAX CLASS ID G UINT Highest supported class number 0x00 653 (0x03) NUMBER OF INSTANCES G UINT Number of instances 0x00 024 (0x04) OPTIONAL ATTRIBUTE LISTNUMBER OF AttributsOPTIONAL AttributsG STRUCT ofUNITARRAY of UNITNumber of attributesList of optional attributes0x00 010x00 046 (0x06) MAX CLASS IDENTIFIER G UINT Highest number of the implementedclass attribute0x00 077 (0x07) MAX INSTANCE ATTRIBUTE G UINT Highest number of the implementedinstance attribute0x00 04Service code Class Instance100Instance101Service name14 (0x0E) yes yes yes Get_Attribute_SingleReturns the specific attribute's content16 (0x10) No yes No Set_Attribute_SingleModifies a single attribute.
