The significance of the indices can be taken from theSection “Parameter list” of the drive Instruction Manual.For a descriptive element, the number of the required element is transferred. The significance of the descriptiveelements can be taken from the PROFIBUS profile, variable-speed drives (VDI/VDE 3689).IND Example 1: Read value of parameter P101.4This example details the decoding of the task IND of example 1 in the Use of PKW object section 4.2.1 previously.(IND):P101 (=065 hex): Rated motor voltageRead parameter value with index 4.Parameter index (IND)Bit No.: 15 8 7 0Byte 3 Byte 2Binary 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0valueHEX value 0 0 0 4Bits 8..15:Bits 0....7:Value always 0Index of parameter or the number of the descriptive element26 Siemens AG 477 759 4070 76 J AA-74SIMOVERTMASTERDRIVES Betriebsanleitung/OperatingInstructions
