 <WIN> (Window) = a string of 3 numeric character indicating the
window number (from ‘000’ to ‘999’); for the meaning of each
window see the relevant paragraph.
 <COM> (Command) = 0x30 to read the window, 0x31 to write into
the window
 <DATA> = an alphanumeric ASCII string with the data to be
written into the window. In case of a reading command this field
is not present.
The field length is variable according to the data type as per the
following table:
Data Type Field Length Valid Characters
Logic (L) 1 ‘0’ = OFF
‘1’ = ON
Numeric (N) 6 ‘-‘, ‘.’, ‘0’ . . . ‘9’ right justified with ‘0’
Alphanumeric (A) 10 from blank to ‘_’ (ASCII)
 <ETX> (End of transmission) = 0x03
 <CRC> = XOR of all characters subsequent to <STX> and
including the <ETX> terminator. The value is hexadecimal coded
and indicated by two ASCII character.
The addressed SLAVE will respond with an ANSWER whose
structure depends from the MESSAGE type. When the MESSAGE is a
reading command, the SLAVE will respond transmitting a string with
the same structure of the MESSAGE.
NOTE
Using the RS-485 interface, the message structure remains identical to the one
used for the RS-232 interface, the only difference being that the value assigned
to the ADDRESS <ADDR>.
The controller can answer with the following response types:
Type Length Value Description
Logic 1 byte - after a read instruction of a logic window
