• Variable type and address to start writing
Refer to "Address map" for the different variable types and the start writing address.(

• Number of elements
Specifies the number of variables to be written.
• When the start writing address is an address within the variable area and the end writing address (the start
writing address plus the number of elements) exceeds the valid addresses of the variable area, then if the
number of data up to the end of the end address is within the range specified by the number of elements, writing
is done and the end is normal. In this case, the number of data written will be fewer than the number of elements
specified in the command. Further, if the start writing address is outside of the variable area, there will be a start
address out of range error.
• Response code
Refer to “List of response codes” for details about each response code. (
