• Command code
Specifies the command for each command type. With parameter read/
write commands and program parameter read/write commands, this
becomes the parameter No.
• Data
Specifies the set value or setting content. With the parameter read
and program parameter read commands, set dummy data "0000". In
the response, this is inserted only when the end code is "00".
Currently, if a command is used for invalid parameters (parameters that do not
satisfy the conditions of use in Chapter 5), the "undefined" error (end code: IC)
response is returned.
