(6) Status feedback
The basic running status of slave machine responded from slave machine to main
machine exists in all types of data frame (Slave machine responds the 4th and 5th
bit).

(7) Checksum
The sum of ASC II code value (ASC II code format)/hexadecimal value from slave
address to setting data/running data.
(8) Frame end
Hexadecimal “0DH” is ASC II code of “CR”.
When the slave machine is in fault status, namely status feedback
data is "20H", the 7th and 8th data (data address) of feedback data
frame represents fault code.
