♦ CHK (check sum) description
Ascii mode use LRC (Longitudinal Redundancy Check)
check sum. The calculation method of LRC check sum
is that add up ADR to content of last data (only get
binary from result), and get 2’s complement result, then
it is LRC check sum.

♦Exception response
In normal situation, Remote I/O device receive
command message from Master Device, and send
back a normal response message (exclude broadcast
message). If because of communication error, Remote
I/O is unable to receive correct message, or receive
correct message but is unable to handle it, then it will
send back an exception response to Master Device. (In
the exception response, the most significant bit of the
original command code is set to 1).
Following is communication command 06H and
response of exception code 02H

Note : Calculation of CRC check sum
Rtu mode use CRC (Cyclical Redundancy Check)
check sum. Calculation method as follows,
(1) Input content is 16bit register of FFFFH(CRC
register)。
(2) Use first byte of command message and lower byte
of 16bit to do Exclusive OR operation, and store
result to CRC register.
(3) Move content of CRC register 1bit to the right.
Maximum bit is filled 0.
(4) Check value of CRC register’s lowest bit. If it is 0,
then repeat (3). If it is not 0, then use CRC register
and A001H to do Exclusive OR operation, and store
result to CRC register.
(5) Repeat (3) and (4) until content of CRC register is
moved 8 bit to the right. At this time, this byte is
finished.
(6) Repeat (2) to (5) to byte of next command message
until all bytes are finished. Content of CRC register
is check sum.
(7) When sending CRC value, send lower bit first and
then send high bit.
♦ Command code 06H write one word
