Example:
− writing request of logic window n. 10 with the
logic value '0' (OFF):
MASTER to SLAVE: <0x02> + <0x80> +
<'010'> + <0x31> + <0> + <0x03> +
<'82'>
SLAVE to MASTER: <0x02> + <0x80> +
<0x6> + <0x03> + <'B2'>
When the MESSAGE has a wrong <CRC>, the
SLAVE will respond with the following string:
<STX>+<ADDR>+<NACK>+<ETX>+<CRC>
where <STX>,
<ADDR>,
have the meaning previously discussed, while
<NACK> = 0x15.
When the MESSAGE requires an access to an un-
known window, the SLAVE will respond with the
following string:
<STX>+<ADDR>+<'2'>+<ETX>+<CRC>
where <STX>,
<ADDR>,
have the meaning previously discussed.
When the MESSAGE is a writing command to a
window, but the data is of a wrong type, the SLAVE
will respond with the following string:
<STX>+<ADDR>+<'3'>+<ETX>+<CRC>
where <STX>,
<ADDR>,
have the meaning previously discussed.
When the MESSAGE is a writing command to a
window, but the data has a value out of the admit-
ted range, the SLAVE will respond with the follow-
ing string:
<STX>+<ADDR>+<'4'>+<ETX>+<CRC>
where <STX>,
<ADDR>,
have the meaning previously discussed.
When the MESSAGE is a writing command to a
reading only window, or it is a reading command of
a writing only window, the SLAVE will respond with
the following string:
<STX>+<ADDR>+<'5'>+<ETX>+<CRC>
where <STX>,
<ADDR>,
have the meaning previously discussed.
