(4) function code 10H: write several data in the register
N ote: V5/VB5 inverters only support one pack of data write.
For example: write P0.06=50.00Hz in inverter address 01H.

RTU mode : Double bytes with hex
CRC field is the binary value has two bytes ( 16 bits ), it is added to the message after calculating ; when added, the first is
low byte and the seco nd is high byte, therefore, the last byte of the sended message is high byte. Then the receiving device
cauculate CRC which has received message again and compared it with the value in CRC field. If the two values are not the
same, the device will take this message as fault and abandond it without any responses , and then receive next frame data.
Please refer to MODBUS protocol instruction for calculate method of CRC verif ication.
