Error Check Calculating:
CSUM = 0 – (Slave_Add + Function + … + Last_data)
(STX and CSUM are neglected while calculating CSUM)
Tool for counting:
0 1 2 3 4 5 6 7 8 9 A B C D E F
Example:
@|01|10|0008|0001|02||0006|DE|
To get the check sum (here FA) you have to sum following numbers first:
01+10+00+08+00+01+02+00+06 = 22
Now you have to subtracte 22 from 00:
00 - 22 = DE
(Calculation examples: 00 – 10 = F0 ; 00 – 11 = EF)
