Data Formats
Commands
The command code and text for the command are stored in memory as oper-
ands and the transmission is executed using the required parameters. The
specific method depends on the programming method being used. Prepare
the transmission data from the command code to the end of the text (with the
data determined by the individual command), and execute the library function
for message transmission. There are two bytes available for the command
code and 0 to 2,000 bytes for the text.
Responses
When the library function for message reception is executed, the data from
the command code to the end of the text (with the data determined by the indi-
vidual command) is stored as reception data, as shown in the following dia-
gram. There are four bytes available for the command code and response
code, and 0 to 1,998 bytes for the text.
