With the exception of blocks DB 99 and FB 877, you must create the blocks listed below
for each connected inverter drive:
n FB 881 - VMC_InitV1000_RTU
Ä
507
– The FB 881 - VMC_InitV1000_RTU initializes the corresponding inverter drive
with the user data.
– Before an inverter drive can be controlled, it must be initialized.
– UDT 881 - VMC_ConfigV1000RTU_REF
Ä
504
– UDT 879 - VMC_AxisRTU_REF
Ä
504
n FB 879 - VMC_ReadParameter_RTU
Ä
506
– With this FB you have read access to the parameters of an inverter drive, which is
connected serially via Modbus RTU.
– The read data are recorded in a data block.
– UDT 879 - VMC_AxisRTU_REF
Ä
504
n FB 880 - VMC_WriteParameter_RTU
Ä
507
– With this FB you have read access to the parameters of an inverter drive, which is
connected serially via Modbus RTU.
– The data to be written must be stored in a data block.
– UDT 879 - VMC_AxisRTU_REF
Ä
504
n DB 100 - A1_V1000
– For each inverter drive, which is serially connected via Modbus RTU, a data block
must be created.
– UDT 879 - VMC_AxisRTU_REF
Ä
504
– UDT 881 - VMC_ConfigV1000RTU_REF
Ä
504
n FB 882 - VMC_AxisControlV1000_RTU
Ä
509
– With this block, you can control an inverter drive, which is serially connected via
Modbus RTU and check its status.
– UDT 881 - VMC_ConfigV1000RTU_REF
Ä
504
– UDT 879 - VMC_AxisRTU_REF
Ä
504
– UDT 878 - VMC_ComObjectRTU_REF
Ä
504
n DB 99 - ComDataSlaves
– For the communication data of all the inverter drives (max. 8), which are serially
connected via Modbus RTU, a common data block is to be created.
– UDT 877 - VMC_ComSlavesRTU_REF
Ä
504
– UDT 878 - VMC_ComObjectRTU_REF
Ä
504
n FB 877 - VMC_ComManager_RTU
Ä
505
– The device ensures that only 1 inverter drive (Modbus slave) can use the serial
interface. If several inverter drives are used, this block, as communication man-
ager, sends the jobs to the respective Modbus slaves and evaluates their
responses.
– UDT 877 - VMC_ComSlavesRTU_REF
