6-2-2 Parameters
All parameters are specified in hexadecimal unless otherwise specified. Where
decimal is specified, it is indicated by BCD.
6-2-3 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 spe-
cific 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 individual
command) is stored as reception data, as shown in the following diagram. There
are four bytes available for the command code and response code, and 0 to
1,998 bytes for the text.

Note When multiple networks are connected, there are limits to the amount of data
that can be transmitted or received via the Controller Link Network and the host
link function.
