The amount of data that can be transmitted at one time depends on the type of
data, and data can be received only from the specified starting address and size.
Refer to the Address and Size given in
Individual Parameter Transmission

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.
