13.5.7 Drive specific blocks
13.5.7.1 UDT 877 - VMC_ComSlavesRTU_REF - Modbus RTU data structure communication data all slaves
This is a user-defined data structure for the communication data of the connected
Modbus RTU slaves. The UDT is specially adapted to the use of inverter drives, which
are connected via Modbus RTU.
13.5.7.2 UDT 878 - VMC_ComObjectRTU_REF - Modbus RTU data structure communication data slave
This is a user-defined data structure for the communication data of a connected Modbus
RTU 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 data
This is a user-defined data structure that contains status information about the inverter
drive. 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 configuration
This is a user-defined data structure containing information about the configuration data
of an inverter drive, which is connected via Modbus RTU.
13.5.7.5 FB 876 - VMC_ConfigMaster_RTU - Modbus RTU CPU interface
This 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 your
project.
In Siemens SIMATIC Manager, you have to copy the SFC 216 from the
Motion Control Library into your project.
