Calculation of FCS

(RS = 0 FMODBUS . RTU code) : FCS = CRC .16 (Cyclic redundancy check)
Procedure of CRC-16 calculation

To load FFH FFH to the 16 bit CRC register

1.
To exclusive OR (*) the first byte of the message format with the low order byte of the 16 bit CRC

2.
register, then put the result in the 16 bit CRC register.
To shift the CRC register one bit to right (toward the LSB) and fill the MSB with zero.

3.

o repeat the step 3 If the carry flag is 0 (LSB is 0), Exclusive OR the CRC register with A001H

T

4.
which is the v
register.
To repeat the step3 and 4 until the 16 bit CRC register is shifted 8 times

5.

o repeat from step 2 to step 5 for the next byte of the message format until final byte of message is

c
To get the CRC value by changing the high order and low order byte of the final CRC register.

3.

dure of LRC calculation

To add all bytes in the message format, excluding the start code F and ending code (0DH 0AH),
then put this value in an 8-bit field
To get a Two's complement from this 8-bit field. it is named Y (8-bit field also)
