13.5.7 Drive specific blocks13.5.7.1 UDT 877 - VMC_ComSlavesRTU_REF - Modbus RTU data structure communication data all slavesThis is a user-defined data structure for the communication data of the connectedModbus RTU slaves. The UDT is specially adapted to the use of inverter drives, whichare connected via Modbus RTU.13.5.7.2 UDT 878 - VMC_ComObjectRTU_REF - Modbus RTU data structure communication data slaveThis is a user-defined data structure for the communication data of a connected ModbusRTU slave. The UDT is specially adapted to the use of inverter drives, which are con-nected via Modbus RTU.13.5.7.3 UDT 879 - VMC_AxisRTU_REF - Modbus RTU data structure axis dataThis is a user-defined data structure that contains status information about the inverterdrive. This structure serves as a reference to the general axis data of the inverter drive.13.5.7.4 UDT 881 - VMC_ConfigV1000RTU_REF - Modbus RTU data structure configurationThis is a user-defined data structure containing information about the configuration dataof an inverter drive, which is connected via Modbus RTU.13.5.7.5 FB 876 - VMC_ConfigMaster_RTU - Modbus RTU CPU interfaceThis block is used to parametrize the serial interface of the CPU for Modbus RTU com-munication.Please note that this block internally calls the SFC 216.In the SPEED7 Studio, this module is automatically inserted into yourproject.In Siemens SIMATIC Manager, you have to copy the SFC 216 from theMotion Control Library into your project.ParameterParameter Declaration Data type DescriptionBaudrate IN BYTE Speed of data transmission in bit/s (baud).n 04h: 1200baudn 05h: 1800baudn 06h: 2400baudn 07h: 4800baudn 08h: 7200baudn 09h: 9600baudn 0Ah: 14400baudn 0Bh: 19200baudn 0Ch: 38400baudn 0Dh: 57600baudn 0Eh: 115200baudDescriptionVIPA SPEED7Motion control - Simple Motion Control LibraryUsage inverter drive via Modbus RTU > Drive specific blocksHB00 | OPL_SP7 | Operation list | en | 18-30504
