For example: If the data classification value in the frame sent by main machine is 0,
the feedback information of slave machine is 400015,which means that 4 represents
voltage class – 380V; 0 is feature information value; 0015 represents power–1.5kw.
1.3.2 Command classification 1- Read running parameters of slave machine
Main machine sending frame size is 14 bytes, while slave machine response frame
size is 18 types.
