The amount of data that can be transmitted at once time will depend on the type of data,
and data must be requested using a specific starting address and size. Refer to the
Address and Size listed in "Parameter address map" (p. 104).
*
Data larger than 128 bytes must be divided into packets of 128 bytes or less. If “Data Set
1” is transmitted successively, there must be an interval of at least 40 ms between
packets.
*
Regarding the checksum please refer to p. 109.
3. Parameter address map
(Model ID = 00H 2EH)
This map indicates address, size, range of data (value) and description of parameters which
can be transferred using "Data set 1 (DT1)".
All the numbers of address and size are indicated in 7-bit Hexadecimal-form. All the
numbers of data are indicated in Decimal-form.
Addresses marked at "#" cannot be used as starting addresses.
