Master DrivesCBD05/20/994 Data transfer via DeviceNet4.3 Process data area (PZD)4.3.3 Instructions and rules regarding process data processingExample:Connecting-up the setpoints in the drive:P443.01 (Source main setpoint) = 3032P554.01 (Source ON/OFF1) = 3001 (using control word 1)P584.01 (Source Technology regulator enable) = 3004 (using control word 2)P526.01 (Source Technology regulator setpoint) = 3005Connecting-up the actual values in the drive:P694.01 = 968 (status word 1)P694.02 = 218 (main actual value as 32-bit value -->)P694.03 = 218 (same parameter No. in 2 consecutive indices)P694.04 = 553 (status word 2)P694.05 = 3 (output voltage)P694.06 = 4 (output current)P694.07 = 5 (output power)4.3.3 Instructions and rules regarding process data processing♦ The lowest significant byte (for words) is always sent first and the lowest significant word (for double words).♦ Control word 1 must always be contained in the 1st word of the received setpoints. If control word 2 is required,this must be located in the 4th word.♦ Bit 10 “control from the PLC” must always be set in control word 1, otherwise the drive will not accept the newsetpoints and control words.♦ The consistency of the process data is guaranteed within the data of a DeviceNet IO Message Connection.Even if more than 4 words are required, the data is not sent to the drive until all data has been transferred throughthe DeviceNet bus. Thus, all setpoints and control words are accepted by the drive at the same instant.Siemens AG 477 759 4070 76 J AA-74 35SIMOVERTMASTERDRIVES Betriebsanleitung/OperatingInstructions
